BLIMEY !!!

this is getting a little heated L+G`s .

i personally believe that when i got my CCNA if i had been asked to 
configure BGP (even Basic) on an internet connecting router for a 
small-medium sized company...i would have run away screaming...

Ask yourselfs this there are three grade`s of Certifications at cisco

Associate
Profesisional
Expert

from a company manager`s point-of-view (no offence fred)

Whom would you prefer be touching your internet facing router ...

yes i am aware that to most of us they don`t mean tuppence (i.e howard/pris)
but the plan truth is people NOT in the know rely on the badges

RE: FW: Opinions on running Hybrid vs Native mode [7:73342]

[Neal, Stephen (Stephen)]

Here is the question/answer note from Cisco:

What is the difference in failover behavior or performance in the Catalyst
6500 between IOS (native) and Catalyst OS + MSFC IOS (hybrid)?  
Answer: The CatOS (hybrid) High Availability feature synchronizes the
protocol states between the active and standby supervisor engines, allowing
for supervisor failover to take place in 1~3 seconds. IOS Software (native)
Enhanced High System Availability (EHSA or RPR) and Route Processor
Redundancy Plus (RPR+) do not synchronize protocol state between the active
and standby supervisor engines, allowing for supervisor failover to take
place in 30~90 seconds. They key here is that IOS Software (native) links
the Supervisor and MSFC together as a unit. Therefore, the failover is a
more complex process than with simpler distributed components. The CatOS
(hybrid) treats the Supervisor and MSFC separately. White Paper Comparison
of the Cisco Catalyst and Cisco IOS Operating Systems for the Cisco Catalyst
6500 Series Switch -Version 2

When you say failover at 2-5 seconds...are you talking about from one Sup

seconds makes me think of the sup mods and 90 seconds makes me think of
spanning tree.

EIGRP Load Balancing ??'s [7:71607]

[Stephen Manuel]

Group, 

 

I have a customer that has two locations connected via 2-Full
point-to-point T1's. 

 

The customer has a 1720 at each location. 

 

The customer is using EIGRP to load balance the two locations. 

 

The networks at each location show in the routing tables with the same
administrative distance. 

 

Everything is fine up to this point. 

 

However, when I look at the traffic statistics for each of the T1's, the
first T1 has significantly higher utilization. 

 

My research has led me to believe the reason that traffic isn't spread
more evenly over the T1's is due to the way the 1720's switch the
traffic. 

 

It's my understanding that by default the 1720's use per-destination
load balancing in the type of scenario my customer has. 

 

Since only one network is at each location this would explain the
utilization issues. 

 

The solution appears to be for the customer to implement per packet load
balancing. 

 

Am I correct on my points so far ??

 

If I implement per packet load-balancing for the customer, is the
command to do this no ip route-cache ??

 

If yes, on what interface do I place the command, if not what are the
command or commands and how are they implemented ??

 

One of the warnings I've read about concerning per packet load-balancing
is that low end routers like the 1720 may not be able to handle, should
I be concerned about the 1720's ??  

The customer has a pair of 2621's we could use in place of the 1720's.

 

Bottomline, the customer would like to load balance the two locations
via the two T1's move evenly, am I proceeding the right direction ?? 

 

If not, what recommendations would others offer. 

 

Thanks in advance. 

 

Stephen Manuel

RE: DS3 slow connection problem. [7:65491]

[Stephen Bailey]

Hello all,

I am a collegue of Mark's who has been working on this fault over the
weekend with Mark.

We have done some further tests today and we are still experiencing errors
on the line, here are some of the results we have seen:

1.) Each time we have changed the clocking on the line, we have bounced the
link either side.  (We used the shut & no shut commands)

2.) With the 7507 set to Internal & the 7204 set to Line, we see that the
errors build up alot slower on the 7204 end.  However any other
configuration with the clocking seems to generate more errors on the 7204 end.

3.) We have replaced the coax cable from the 7204 to the Carrier equipment,
but it seems that the new cable is not correct, as things get worse.

We are currently in the process of bringing up a 2nd link so that we can
take this 45mbps circuit down for testing hopefully today.  I'll post an
update when we get something back from the carrier.

Thanks again

Catalyst 2924 XL - ip routing??? [7:63553]

[Stephen Hoover]

A friend of mine recently purchased a Catalyst 2924 XL switch - 24 port
10/100 Ethernet switch - 1U no expansion ports.

We were looking at the IOS configuration and I noticed a line that said "no
ip routing." I went into the global config mode and sure enough I could
enter the command "ip routing."

It didn't appear to do anything, and I know this is only a layer 2 switch -
so my question is - why is it an available option? Just curious, don't
really need to know - hoping someone familiar with this particular switch
could answer it though.

Thanks!

Layer 3 switching and VLANs - an epiphany [7:63240]

[Stephen Hoover]

Ok, its 1:29AM CST - and I am setting here chewing on this switching study
guide information about VLANs. I think I see where my confusion has come
from and what the answer is now.

Layer 3 switching does not require VLANs, but what is DOES require is a
physical port connection on the common L3 switch for every IP network that
is connected to the L2 switches. (Hosts on the same L2 switch that are
configured to be in 2 different IP networks.) This is not always possible
nor administratively friendly.

With VLANs, you can create the equivalent of sub interfaces on a single port
on the L3 switch - hence trunking. You cannot trunk multiple IP networks
(without VLANs) on a single port connection the L3 switch, because you
cannot create Ethernet sub-interfaces...

That's where I was missing it.

I think it both Vicki and Jens mentioned something about this.

Of course if I am off-kilter here, someone please slap me about :) Otherwise
I am confident this is where my misunderstanding really occurred.

Thanks to EVERYONE who responded - you are all a great group of people to
stick it out until this was beat into my thick skull!!!

Re: Does MLS (Layer 3 switching) require VLANs? [7:63147]

[Stephen Hoover]

Ken,

Thanks for the input on this discussion. I follow and understand your
example without any problems.

Now if taking it back to the original original question - Does L3
switching require VLANs - produces this question for your example:

You state 1 fiber feed for both Science and Engineering in the Labs
building. I am then assuming that they are all connected to the same set of
switches (Layer 2) in that building.
Could you have not just simply assigned the hosts for Science to 1 IP
network and the hosts for Engineering to another IP network - then created
respective gateway interfaces for each network back on the common Layer 3
switch and accomplished the same thing??

If the answer is yes, I will followup with another question. If the
answer is no, then please explain.

Thanks!!

My posts on Layer 3 switching and VLAN [7:63224]

[Stephen Hoover]

For some reason my responses are taking a REALLY long time to get to the
list in relation to other people's responses, so the conversation is losing
continuity.

I sent an email at 8:55PM CST and I am writing this at 10:19PM CST and my
8:55 post still has not made it to the list.

This is adding to the confusion. I think I had it all straight at
Priscilla's posting with this history of LANs.

Thanks!

I caused the confusion in this situation - I asked what would happen if your
gateway was 3 or 4 L3 switches away. What I should have asked was what would
happen if your gateway was 3 or 4 distribution layer switches away. I was
referring to the L3 switches as devices instead of function. In my example I
was trying to illustrate how extending a VLAN across the core created a poor
path for the client on the far side. When I said that the client on the far
side is a L3 switch away from it's own gateway, what I meant was that the
client's network path would have to cross the L3 switch (but at the L2
level) in building B to get to it's gateway on the L3 switch in building A.
In other words the host is crossing the core through the L3 switch in
building, but it is crossing that L2 level. Sorry for that.

Re: Does MLS (Layer 3 switching) require VLANs? [7:63147]

[Stephen Hoover]

I appreciate everyone's input on this subject to help me understand this
concept.

As far as the newbies comment goes - I most definitely am. I'm about as
green as they come. I have both my CCNA and my CCDA, but my only real
experience is installing 2 T1s (at different locations) and configuring NAT
for them. I have large amount of knowledge, just no experience. It has been
my goal and my dream to become a serious network engineer for the last 6
years, but I just cannot seem to get a job that offers any experience.
Everytime I get a "network" position, I just seemed to end up doing desktop
support.

When I first heard the term Layer 3 switching (some 4 years ago now) the
first thing that popped into my mind was a switch that can route. I never
even heard of a VLAN until a couple of years ago.

The Cisco Study guide starts off talking about VLANs, and moves right into
Inter-VLAN routing without ever really discussing Layer 3 switching as a
seperate process. This is really where my confusion started. The book makes
it sound like L3 switching is directly dependent on VLANs, and I just didn't
see it - it wasn't something I was just willing to accept.

Further more, the book states that VLANs allow for physical location
independence, but is also says that VLANs should not cross the core - those
2 statements seem partly contradictory to me.

Here is a summary of how I see VLANs now.

  Layer 3 switching is possible without VLANs (however the opposite is not
true. Well at least not without some form of Layer 3 intervention.)

 VLANs simply the administration behind Layer 3 switching design.

 Physical location (port location) independence is ok in front of the
layer 3 switch that is the the hosts gateway. Up to the hosts distribution
switch.

VLANs extending beyond the distribution layer switch across the core is
generally not a good idea - possible, but not recommended. This is the "flat
earth" design that Priscilla mentioned - VLANs that extend across the entire
internetwork.

Thanks!

HTH,

Thank you for these comments - this clears up a lot of confusion for me.

To sum, just to make sure I really have this:

Layer 3 switching is possible without VLANs (however the opposite is not
true. Well at least not without some form of Layer 3 intervention.)
VLANs simply the administration behind Layer 3 switching design.
Physical location (port location) independence is ok in front of the

Re: Understanding VLANs - how they remove the physical [7:63194]

[Stephen Hoover]

Ok, let me see if I can simply this:

A post that Jens Neelsen made says "a layer3 switch (e.g.3550-EMI) does not
have layer3 interfaces. All interfaces (Fastethernet and GigabitEthernet)
are layer2
interfaces. They can not have IP addresses." Further he adds "The VLANs are
the (virtual) interfaces to the routing engine (=layer3 switch). Layer2
interfaces are grouped into different VLANs and the Layer3 switch (=Router)
enables the communications between these VLANs. "

Ok then the question is - if you have a LAN with ALL switches and NO
routers - how do you define a gateway on the client?

Example:

2 L2 switches. All hosts on switch 1 are in IP subnet 192.168.1.0/24 and all
hosts on switch 2 are in IP subnet 192.168.2.0/24. Both L2 switches are
connected to a single L3 switch with a router engine in it.

Where do you define the gateways at? In order for hosts on L2 switch 1 to
communicate with hosts L2 switch 2, the client has to have a gateway to
forward to correct??

Oo ok, now THAT statement leads me to believe the L3 switching IS
possible without VLANs.

Understanding VLANs - how they remove the physical boundaries [7:63173]

[Stephen Hoover]

Ok, I am really struggling to understand the usefulness of VLANs here. In
the Switching exam book, it states that VLANs remove the physical boundaries
of the network and a user anywhere on the network can be a member of any
VLAN (IP subnet). Now I do understand this concept, but consider the
following scenario..


Building ABuilding B


VLAN1-Switch1   Switch 1 VLAN3
 ||
 VLAN2Switch 2  Switch 2 VLAN 1
 ||
 ||
 L3 switch A--COREL3 switch B
  (has router engine)   (has router engine)
 \ /
   \ /
 \ /
   \ /
 \ /
\/
 Servers
VLAN 4


Now lets say that VLAN1 is defined in building A, but some people in
building B need to be part of VLAN1. Doesn't that make L3 Switch A the
default gateway for the VLAN1 user in building B? In which case that user
has to cross the core back to switch A to get his routing to the servers?
Why would you EVER want a network configured this way?? Or even worse, what
if your respective gateway was 3 or 4 L3 switches away? That just doesn't
seem practical to me.


Thanks!

Vicki,

You mention the use of secondary IP's. On a L3 switch (a switch with the
router engine in it) is it not possible to define Ethernet sub interfaces
instead of using secondary IPs - without VLANs defined?


I'm sorry to be so thick, I'm just not getting it. If a L3 switch (with
a routing module/engine in it) is essentially a wire speed router, then the
VLAN just seems like an additional identifier on top of the L3 address - and
doesn't really serve any purpose. In my previous example, 2 hosts on the
same L3 switch, but on 2 different IP subnets - wouldn't a defined Ethernet
subinterface be each clients respective gateway, and thus normal L3 routing
would occur, just at switch speeds


Thanks again!

Stephen Hoover

Right, I understand that inter-VLAN routing requires L3 switching - but is
the opposite also true? Does L3 switching require VLANs to be defined? If
that is the case, then it would lead me to believe that L3 switching is
based on VLAN info and not on the IP address, but I don't think that is
correct.

Thanks for the help!

Does MLS (Layer 3 switching) require VLANs? [7:63147]

[Stephen Hoover]

I am studying for the CCNP Switching exam and it covers VLANs and layer 3
switching moderately. It states that Cisco recommends a 1 to 1 mapping of
VLANs to subnets. It also states that VLANs can be used to break up
broadcast domains.

When you create different subnets, you are already breaking up broadcast
domains, so does layer 3 switching require the use of VLANs to actually do
the switching?

Say for instance I have 2 hosts on the same layer 3 switch, but the two
hosts are on 2 different IP subnets (No VLANs are defined). Host A wants to
talk to host B. Can the switch not look up the routing info and then know to
switch to that port? I am not seeing where the requirement for the VLAN
comes into play.

If VLANs are required for layer 3 switching, is that pretty much standard
across the industry, or that a Cisco only thing?

Thanks!

VoIP QoS [7:55597]

[lamb stephen]

Group,
   Hoping that someone can help me out with a VoIP QoS issue that I am
currently dealing with. I work for a service provider, and I am currently
troubleshooting a VoIP over frame relay quality complaint. My end user has a
768K host with four 256K drops dedicated solely to VoIP traffic. My customer
states that he experiences intermittent jitter on his calls, but they follow
no real pattern. We have had his vendor place test calls, and sometimes 7
simultaneous calls can
go through fine while 3 simultaneous calls will experience poor call quality
and excessive jitter. The end user's vendor is of no real help with this
issue stating that his configurations are fine and the trouble must be with
the WAN link.
   I have verified that the entire network is clean, no T1 performance
monitor errors , no input errors on the customer's serial interfaces, and no
input errors to my frame switch. No apparent utilization issues, the host
averaged 50% port utilization during a 24 hour sniff. We have also verified
the drops are not receiving any FECNs or BECNs. I have a copy of the
customer's router
configurations and his map-class statements appear to be correct as well.
His CIR and MINCIR are set to match the frame relay PVC CIR in my network
(which I believe means that he has configured the statements to prevent any
bursting, please correct me if I am wrong).
   On to my question. The only discrepancy I find with this customer's
configuration is his queuing. On all four of his drop routers he has
configured WFQ, on his host he has no queuing specified. Could this be the
cause of all of his problems? Would WFQ be the most desirable method? What I
have read in the past led me to believe that a fragment statement in the
map-class was the most
desirable because it activated the dual-FIFO feature on the physical
interface. I do not have a great deal of experience with VoIP so all I have
to go on right now are theories. Any direction is greatly appreciated.

Thanks,
Steve Lamb

Re: e-mail server for Mac OS [7:54586]

[Stephen Hoover]

I personally think upgrading to MAC OS X would most definitely offer more
choices.

I use a combination of Postfix and Qpopper (on FreeBSD) both of which I know
will run on MAC OS X.

Communicate PRO is supposed to be an EXCELLENT commercial email server with
SMTP/POP/IMAP capabilities all built in. I have not used it myself, but it
comes highly recommended on my lists. There is an online demo on Stalker's
website. http://www.stalker.com/CommuniGatePro/

If you want to go all open source I would use Postfix - as of yet it doesn't
have all the bells and whistles of Sendmail and Qmail, but it is ROCK SOLID,
and has had no significant security problems. Postfix supports virtual
domains, virtual users (non system account users) in LDAP and MySQL. It has
various built in anti UCE controls as well. It is also consistently shown to
be one of the fastest MTA's out there.

Here is a good article on MAC OS X and Postfix..

Re: 802.11a [7:47594]

[Stephen Manuel]

Dennis,

The 802.11a standard operates in a different part of the broadcast spectrum,
5ghz versus 2.4ghz in the 802.11b standard.

It also operates with a high throughput, some vendors are touting a 72mb
"turbo rate"versus 11mb for 802.11b.

The issus is that the 802.11a and 802.11b standards are not compatible with
each other, meaning if you have an AP or wireless card you can't use it to
access or accessed with equipment from the other standard.

I've seen some vendors announcing equipment that supports both standards but
so far this isn't the norm.

The IEEE 802.11 committee is supposedly working on a 802.11g standard that
makes the A and B standards compatible.

Recently when I purchased my Linksys AP and Orinoco Gold cards, I almost
went with the A standard simply because of the added speed, but I realized
the B standard was installed in far more places. For instance, alot of
coffee shops, airports and other businesses are installed AP's as added
service, if you plan on using one of these public AP's more than likely it
will be of the 802.11b standard.

Bottomline, I decided to wait for a more compatible standard before moving
away from the 802.11b standard.

Re: Rogue Wireless LANs [7:47287]

[Stephen Manuel]

Tom,

I'm not speaking jest, I have used netstumbler to find wireless networks
that are wide open, some
are in major companies.

However, I turn off my client manager before I go wardriving, that way I
don't accidentially connect
to someone's network without authorization. I can't see how this is
considered hacking.

When I initially approached the 3 companies I mentioned earlier, I had a
developed a 3-page document
on the ease of implementation of wireless networks and the inherit security
risks associated with wireless networks. I
didn't mention to any of the 3 that I had already detected their networks
and how wide open they really were.

I am toying with the idea of sending specific information to them about
their wireless networks, like the MAC address of the AP, the SSID, the
network name, the exact location on a map of the AP, the manufacturer of the
AP,  if WEP is turned on, plus if I really want to get serious I could tell
them if the AP is issuing IP addresses via DHCP and their network settings
if it is.

The question I have is, would the company be happy to know that they have
security holes and were alerted to it, would they threaten me by calling law
enforcement, or would they ignore me as a nut or go and fix the problem
without hiring me to do it for them.

I was simply amazed at the shear number of AP's out there and how many were
in businesses wide open.

Re: Rogue Wireless LANs [7:47287]

[Stephen Manuel]

Neil and others,

Recently I installed in my home a linksys wireless router/switch/ap, it
works great, yes I have wep enabled.

After installing the equipment, I became really interested in wireless
networking, reading some books, looking for a certification track, scouring
websites, etc...

I downloaded netstumbler and acquired all the necessary equipment to do some
serious wardriving. I've logged over 300 AP's, mapped them using Stumverter
and MS Mappoint 2002, it gets down to what side of the street the AP was on,
just to add a little spice to the situation, I've got netstumbler to play a
.wav file when it finds an AP.

Amazingly, 75% of the AP's I've found don't have web enabled. A rather large
number of the AP's use the company name as the SSID or use the vendor
default SSID, ie. tsunami for Cisco.

I'm convinced this whole area of wireless networking is wide open to be
farmed for business. I've been trying formulate a business plan to approach
businesses to help them install a wireless infrastructure properly and setup
security measures for those companies already in the wireless business
without implementing security.

What my research has shown me so far is that without upper managements
support for strict policies with regards to the installation of AP's the
company is playing a game of russian roulette because the current Wireless
Implementation is FULL of security holes.

Depending on how much security you want to implement here's what I would
recommend.

Enable WEP - however airsnort a linux utility can crack wep in a relatively
short time

Disable the SSID Broadcast - most AP's have this option, this will prevent
netstumbler from picking up the presence of the AP which makes it a little
more difficult to associate with the AP. Kismet is a linux utility that will
still detect the presence of the AP by passively sniffing for the wireless
packets.

MAC Filtering - enable it but most AP and Wireless cards allow you to spoof
the MAC address, meaning a wireless sniffer like ethereal can sniff out a
few MAC addresses and a hacker can use one to gain access.

Place the AP outside of the firewall

Create VPN access for those wireless clients needing access to internal
servers.

I'm sure others have done work in this area and can add to the discussion.

BTW, interesting enough the first 3 companies I approached about the
unsecure AP's, 1 denies having wireless networking installed, 2 ignored me.

HTH,

Stephen Manuel

Native Vlan [7:45146]

[Chan Stephen]

Hi all

Can someone tell me what is the purpose of the native vlan in Csico Switch?
What is the feature & main usage on that?

I am wondering if it is a proprietary feature, it will only work through
Cisco Switches only?

Thanks.

Cheers

BGP addressing..i think i iunderstadn but i am not sure [7:45127]

[stephen skinner1]

Chaps..

can i try to explain something about BGP addressing and you chaps point out
were i am or am not going wrong ??..

EG..

i have two bgp routers going to the net ...

i am multihomed to 2 service providers...(and accepting FULL routes)

i have been issued 2 "sets" of ip address to my service providers..

i am using Private AS`s (internally)



ok ..
outgoing traffic...

i take it ...as i have full routes then outgoing traffic has no issue`s as to
how to get anywhere...(i am using gateway of last resort and a DMZ for all my
internal stuff)

incoming traffic ...routes i advertise out to the net...

if i am multihomed... i have two different ip address`s advertising a route
to
my network ..this would cause no problems as there are simply 2 routes on the
net to get to me..

my service providers will use the same private AS number to get to mee
( will it matter if they give me two different private as ...as i
want
to load balance...)..

How would load balancing work.(inbound..)(outbound i understand)...
...the
BGP routers are in the same location so it makes no difference localy..

i get the rest it is just this i am bit shakey on...i dont really understand
how to different SP can give me load balcning...prehpsa it cant...

many thanks


steve

NBMA SVC problem [7:44529]

[Stephen Chan]

Hi all

In the book of Cisco Routing TCP/IP Voulme 1, it mentions that the OSPF
point-to-multipoint network type treats the underlying network as a
collection of point-to-point links rather than a multi-access network,
and OSPF packets are multicast to the neighbors. This situation can be
problematic for networks whose connections are dynamic, such as frame
relay SVCs or ATM SVCs.

But it has not mentioned what is the problematic situation.  Does anyone

know that?

I think that it should not be problematic because InverseARP can cater
for the mapping of the DLCI to the remote IP address even the underlying

network built on SVCs. Is that right?

Thanks.

Cheers
Stephen

NAT & Access List question [7:44357]

[Stephen Hoover]

All,

   I need to setup my first real NAT statement (as opposed to just a PAT
statement) and I need some
help with the Access List config.

   I have a T1 with 6 public IP's, with all my users nat'ing through the
last 2 IP's with an ip nat
pool/source list statement. The list basically blocks outgoing kazaa,
netbios, and morpheus. I have
my email server pat'd to another IP higher in the list and the problem I am
running in to is that
the mail server uses the same IP's in the nat pool statement when it sends
mail out - which is
causing me reverse lookup headaches. So I want to do a true nat statement
for the mail server so
it's sending and receiving IP's are the same and I can get a reverse lookup
setup for it.

   If I understand IP/TCP/UDP correctly, the client establishes a connection
to the service port on
the remote computer and the remote computer in turn establishes a connection
to some random port >
1024 on the client. Is that correct?

   So the issue for now becomes, how to restrict access to the mail server
for just 22, (for remote
management) 25, 110, and 6169 (a webmail server) and still allow the
returning nat connections to
the clients? This is what I picture so far.

access-list 101 permit tcp any (external ip) eq 22
access-list 101 permit tcp any (external ip) eq 25
access-list 101 permit tcp any (external ip) eq 110
access-list 101 permit tcp any (external ip) eq 6169
access-list 101 deny tcp any any lt 1024
access-list 101 deny udp any any lt 1024

then I start to get a bit hazy as to the returning nat connections for the
clients..perhaps
access-list 101 permit tcp/upd any any range 1025-65535?

I'm assuming also that this will be applied in on the Serial interface.

Any help greatly appreciated!!!

RE: TAC [7:42141]

[Stephen Manuel]

Group,

Sorry to be a little late to the topic, but I've not kept up lately :-)

About 1 year ago I left a company that provided a TAC for Cisco, I don't
know if alot of people
know it or not, but Cisco outsources alot of the TAC support. When I worked
at the TAC we were rated
on two things, the number of cases closed and our Bingo Score. The Bingo
score is you average rating from
the surveys each of you have gotten when a case is closed. They're were
small monetary rewards for having
the highest number of closed cases accompanied by the number of High 5 Bingo
scores you had received. BTW, a HIGH 5
Bingo is when a customer gave you all 5's on the survey.

What happens alot is the lesser quality engineers who have been lazy all
month, all of a sudden get serious
at the end of the month realizing they don't have the cases closed numbers
and start taking and immediately closing
the cases, only to have them reopened later by another engineer, eventually
this catches up to the person but it went
on alot more frequently that it should have.

Another thing that happens for instance, the team I worked on initially
supported the 1600-3600 Routers for ISDN,
Frame-Relay, NAT, Access-lists, and other general purpose IOS issues. In the
span of a week, management said you
will start getting 700 router cases, my team got about 1 hour's worth of
training and then were charged with solving 700
cases, of course the 700 router is a completely different IOS which took a
little while to get use to.

I suspect that's what happened, a team was given a new techonology to
support, received little training and then were
asked to start solving cases and maintain the same Bingo Scores, etc

The reason I left the TAC I worked for was monetary, the pay was low, but
the experience was invaluable.

Hope this helps.

Stephen Manuel

ISDN Simulator [7:41896]

[Stephen C]

Ok, I give up.  I am tired of being unable to simulate ISDN on my rack.
Been having to go over to the school to do labs and that is hit or miss on a
person with keys.  I would love to buy an Adtran Atlas 550 as configured by
Cisco for the Academies, who wouldn't.  But the money tree just can't grow
it that fast and even thirteen bills (SlimLine 2) is a bit steep for the ol
wallet.  What is the "shoe string" option or is there?

Stephen

IPX EIGRP Metrics [7:41585]

[Stephen Barlow]

Is there any way to alter the metrics of IPX EIGRP other than changing the
bandwidth on an interface?  Specifically, I want to route IPX traffic over a
40Mbs link instead of a 100Mbs temporarily, and I don't want to alter the
bandwidth on the interface as it will affect the IP routing.
Thank you in advance.

Steve

RE: PAT port range on a Cisco 1604? [7:41001]

[Stephen Hoover]

Well I was looking for a way to specify a port range in a nat statement.

For example:

standart nat/pat statement.
ip nat inside source static tcp 10.0.0.1 21 208.192.100.100 21

I need something like this:
ip nat inside source static tcp 10.0.0.1 64300-64400 208.192.100.100
64300-64400

What I am trying to do is open up a PASV FTP data port range for use on a
FTP
server with non standard ports. As long as I have the server on 20/21 PASV
and PORT
seem to work fine, but when I move the ports to something non standard, I
cannot
connect on the PASV command without having the ports specified and nat'd. I
tried
using cisco's ip nat service command as referenced:

http://www.cisco.com/warp/public/556/6.html

but apparently I am a gump and can't make it work :)

Hi Stephen,

are you looking for a command to limit the ports used by PAT ? AFAIK, this
is not possible through the 'overload' command. If you know exactly which
ports your hosts use, you could set up an extended access list specifying
the ports that you want to allow.

Regards,

Georg

Console Cable [7:39585]

[Stephen Neville]

Hi group

Iam having trouble with using a console cable into any of my routers.  The
problem is when I power on the router, I can see it loading on the screen but
when it comes up press return to get started nothing happens when I do press
return.  I have tried this on all my routers, using hyper terminal and tera
term.  I have made sure the cable is fitted right. The keyboards return key
works on other applications.  This has only just started to happen.  Any
ideas?

2nd Question

Iam trying to connect 2 2501 by the aux port and use them as a frame relay
switch does any one know the configuration for this?

Thanks

Steve

516-CS Terminal Server Configuration ??'s [7:35225]

[Manuel Stephen]

I have recent come into posession of a Cisco 516-CS Terminal Server.

I want to use this device to control a rack of 8-9 routers, switches, etc

I am using a standard Cisco Console Roll-Over cable to connect a port of the
516-CS to the Console Port the Router. In my setup I'm using port 5 of the
516-CS. The loopback address is 192.168.1.1

I have setup a loopback interface on the 516-CS. 

I then issue the following command

telnet 192.168.1.1 2005, I get an immediate respone that the connection is
open and nothing else happpens, I then hit enter a couple of times on the
516-CS which eventually hangs the device and it has to be rebooted.

Here are the config's for the 516-CS and one router. 

Any help, ideas and suggestions are greatly welcome.

You have to have IP connectivity to your neighbor before BGP will work.
Static routes will get you the same thing as RIP.

by entering these commands di I inject a static route?  I can't figure out
where
they came from.  Are they a normal consequence of BGP or ???

Re: T1 install; issue resolved. [7:22162]

[Stephen Hoover]

Thanks again to all of you who responded. Someone had mentioned the number
of timeslots as being a probable cause. I apologize for forgetting the name
of the person who posted that.

You were close - we had the number of timeslots configured correctly, but
the person on the remote end of the link had the wrong speed set - 56
instead of 64.

I did not have access to his configuration and I have not worked with this
person enough to be brass enough to ask for it. Being an individual and far
from being an "expert" I was not prepared to ask a Cisco "guru" in a larger
IT dept to allow me to review his configuration. Obviously if I had had it,
I probably would have caught it.

Thanks again everyone!
Stephen

Re: T1 install; line protocol going down and up every 30 [7:22068]

[Stephen Hoover]

Thanks to all of you who have responded. Here's where I'm at:

The Telco's (two telcos involved) have both said the circuit is sound and
correct. We can loopback both ways down the length of the circuit and it
works ok. To eliminate hardware problems on my end, I have tested this
router and DSU on the T1 in my office. It is a point to point to our ISP.
The router came up, I plugged in our IP's, NAT, ACL info and we were
surfing. My hardware/configuration seems to be working ok. The only thing
left is their hardware/configuration, so I feel that's where the problem
lies. The company I am trying to connect to has over 50 T1's going into
their facility - this is not exactly a new configuration for them.

Admittedly I am not the most seasoned field person. I have installed some
T1's, but not 100's. I feel I must be missing something simple, but I don't
what it is. The default configuration for this DSU is:

clock source - line
encoding - b8za
framing - esf
timeslots/channels - all 24
speed - 64k

I have not modified any of these settings execpt changing the clock source,
trying it both ways. In our office I know the ISP is providing the timing,
so I just left everyting on the DSU to default and it worked beautifully.

Any other ideas?

Thanks,
Stephen

Re: T1 install; line protocol going down and up every 30 [7:21872]

[Stephen Hoover]

I am using an internal DSU on my end. I am not sure what they are using on
their end. I have checked and double checked the linecoding and framing.
This is a SouthWestern Bell circuit, but it passes through a different long
distance carrier. It should be B8ZS, ESF, and HDLC on the layer 2. Again,
when the remote end is set to line, they seem to be fine. When they go to
internal they cause framing errors. This leads me to believe that there
already is a clock signal on their end of the link. Regardless of whether I
go to line or internal my line protocol bounces.

T1 install; line protocol going down and up every 30 seconds [7:21848]

[Stephen Hoover]

I am working on point to point T1 install at a small office. The line
protocol keeps going up and down every 30 seconds and I cannot ping myself.
My keepalive timers are not incrementing. The telco provider says that they
are not providing the clock on this line and that we need to do so
ourselves. My condition remains the same whether I set my clock to line or
internal. The router on the remote end however seems to be ready to go when
they set their clock source to line. When they set to internal, the telco
provider sees framing errors on the line.

Does it seem feasible that there is a clock source somewhere back towards
there end of the line that their router can receive and mine cannot? I am
working with the IT staff on the remote end of the link, but none of us seem
to have any idea where else to go with this problem.

My system works fine when I put my DSU in local loopback and it works when I
put their DSU in remote loopback - so I *think* the hardware is sound.

Any help is appreciated!

Thanks,
Stephen Hoover

Hi ,

i still think it`s the link..i have been told loads of times links are

Re: Help with huge amount of Input/Frame and some CRC errors [7:21657]

[Stephen Skinner]

symon...

sorryi am  asleep


i don`t like the amount of interface resets you are getting...


can you clear counters and watch the amount you are gettingon both 
sides..

int resets cum from the line bieng dropped (g703/line)

i have smds/leased lines and you should not get ANY int resets on a good 
line.

the last time i had this problem it was the BT CSU/DSU that was at fault

that FUNNY you know ...al the BT CSU/DSU (for there 2 meg leased) have an 
X21 port built in

you could also try swapping  the ints (S0-S1)on both sides to see if that 
makes a difference...

Is this a new install??

it IS possible that the G703 converter is stuffedwe use BlackBox 
ones...and they SHOULD work straight out of the box...

Re: Help with huge amount of Input/Frame and some CRC errors [7:21649]

[Stephen Skinner]

in your config 

what is your LMI.(autosence)

have you set the encapsulation command on the int`s

see this link

http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/wan_c/wcdfrely.htm#xtocid221854



input errors usually mean that there is some kind of encap error...(int 
doesn`t understand the packet/frame it`s recieving)

Re: Fastethernet failover [7:21177]

[Stephen Skinner]

hi,

with my new found knowledge on this subject...

why don`t you load share your HSRP by using the
standby preempt and standby track commands..then simply connect the other 
ethernet interface to the other switch running HSRP ...job done...

~BTW I THINK.i`m not sure

List???

i have to diasgreeevery 3 secs a pulse is sent from the active to 
standby.even if you have a route connected to your standbywhen 
thestandby gets any routed packets HSRP (which is layer 1/2) will send 
it to the active master..this wil then route the packets accordingly...

i`m told ther is a way around this but you will have to search the

Re: CCNP Support 640-506 exam difficulty [7:21060]

[Stephen Skinner]

the support exam is as hard as your support knowledge is week...( a crsap 
answer i know)..

i spent most of my time supporting networks and i found it quite easy..

you will get lots of question about reading sniffer`s ,,basic fault 
finding..and so  on

the lamme series is OK...but i like the support exam cram(it`s all i used to

Re: Can I configure 2 leased line for single channel ? [7:21147]

[Stephen Skinner]

not as far as i am aware

What you COULD do ..is set them up as seperate lines ...and then run 
eigrp/ospf betweeen them ...this will load balance the lines..

you could just upgrade your one line to 256k...also

but there is no serial "etherchannel" varient..

you can do it with isdn using dialer channel`s

Re: 6509 L 3 module [7:20997]

[Stephen Skinner]

i9f i get what you ask correctly ...

the L3 module is a MSFC/RSM this is either a daughterboard on the supervisor 
cards or a seperate card..

basically they are a 2600 router on a card

here are some links to cisco configs

Re: I want some help about this 504 questions [7:20767]

[Stephen Skinner]

i see where you are cominbg from my friend

i believe you are correct on Q2 but incorrect on Q1

if the packets are perfectly formed they will be transported through the 
internetwork..

but as Q1 says

"would cause broadcast
>traffic to be contained within the physical segment?"

from a physical standpoint it is correct..if the gateway you  are sending 
frames to dosent understand those frame it will drop them

"Host interface is constantly sending frame fragments
Host interface is constantly sending frames with CRC errors"

these hosts are basically sending garbage to the gateway and as such the 
gateway won`t know what to do with them ..so it will drop them ..

all brodcast igmp and icmp request`s aslong as properly formatted will 
traverse the internet ok 

yes there are ways and means around this but from the point of view of the 
questionQ1 is correct

Anyone Else ?.

[Stephen Skinner]

ermmm

255.255.255.252...the binary states

1100  last two will give you 4 ip`s and 2 useable ones..

Re: SNMP index numbering [7:19866]

[Stephen Skinner]

hi,

according to our NNM ...it Does do that with Sub-int ,port-channels and 
loopback...it just treats them as ordinary interfaces...

on one of our msm it says port channel1.5 is if index 9...we have other 
int`s

this will try and cheer everyone up...or i will never be spoken [7:19920]

[Stephen Skinner]

thingsd are getting a bit heavy on the list ...and i am trying to releave 
some of the tension felt by our list brothers...

PLEASE i am not making light of the situation..

just trying to help...in my own way

===
i was recently selling someone some equipment ...and the guy is NOt very 
computer litarate..(atleast he can spell)...

and he asked about a warranty...


i said 1 week return to Base

he said "Ohhh.." and sounded quite dissapointed

and i said "if that no goodwe could go for 2 day RTB.."

he again said

Ohhh sounding really very dissapointed ...

so i gave in and asked what wrong

he said" i was hopeing for atleast a year warrenty on the equipment"..

i looked at him funny then realised what he said ...and had to explain 
to him that the warranty was for a year ..this is just the turn around for 
repair`s...

the guy looked very happy ...and i continued talking for 10 mins before i 
realised what he said and spent the next two hours trying not to cry with 
laughter( i know it`s not his fault it`s just no-one has ever said  
that to me before...i suppose it makes sence ,,)



later (this was last week)  i told a collugue this and he didn`t understand 
why i found it funny..

2 hrs later ...he rang me up laughing...because he could see the logic in 
what he saidand agin found it funny...

Ahh Well

and yes we will be observing a 3 minute silence at 11:00 am today...


Thanks and my prayers go with you

Re: Dual FIFO? [7:19691]

[Stephen Skinner]

the only thing i could find was this

http://www.cisco.com/warp/public/788/voice-qos/voip-ov-fr-qos.pdf

which says

"Turn on fragmentation for low speed links (less than 1.5Mbps).
Set the fragment size so voice packets are not fragmented and do not 
experience a serialization delay greater than 20 ms.

Lowest Link Speed in Path Recommended Fragmentation Size

56Kbps 70 bytes
64Kbps 80 bytes
128Kbps 160 bytes
256Kbps 320 bytes
512Kbps 640 bytes
768Kbps 1000 bytes
1536Kbps 1600 bytes

Note: For 1536 Kbps, no fragmentation is technically needed, but 
fragmentation is needed to enable the dual first-in, first-out
(FIFO) queueing system to ensure voice quality. A fragment size of 1600 
bytes enables the dual FIFO, but since 1600 bytes is
higher than the typical serial interface maximum transmission unit (MTU), 
large data packets are not fragmented.

from what it says it`s just multple "stack" queue

sorry i can`t be of more help..

Cheers

steve

Re: quetion of catalyst 5505 [7:19519]

[Stephen Skinner]

you have a hardware error

either the backplane slot is damaged (not likely) ...or the card is faulty..

try moving the card to a different slot and see ..if not order spare card ..

i think(am trying my best to understandit`s been a long day 
(already!!!) and i have a hangover)
