Hmm, I think I know what the question is, however I don't really have an
answer right now if I'm right.

Picture two different scenarios:

1

Workstation A, B and C are connected to a switch that IS NOT running VLAN,
hence they are in the same broadcast domain. The IP addresses are as
follows:

 A   : 10.0.0.10 / 8
 B   : 10.0.0.11 / 8
 C   : 192.168.29.14 / 24

If A wants to send to C, it broadcasts an ARP request for 192.168.29.14
which the switch forwards to C, and C replies back with it's MAC address,
and A can now send to C.

This is however (I believe) a bad configuration.


Actually this won't happen.  Host A has no idea it is on a common broadcast 
domain with Host C.  It will just look at the address and see that it is on 
a different network and because of this it will forward the packet to the 
default gateway.  The only way it would issue an ARP request is if it was 
on the same IP network as Host A.  This is default IP behavior.

2

Workstation A, B and C are connected to a switch that IS running VLAN, and
with the same IP addresses as in example 1, A and B are in VLAN 11 and C is
in VLAN 12 - hence they are in two different broadcast domains.

If A wants to send to C, it broadcasts an ARP request for 192.168.29.14,
but
the switch does not forward it since C is on a different broadcast domain.

A now has to send the data to it's Default Gateway.


I think that the question is : If you take example 2, why doesn't the
switch
just reply to station A's ARP request with C's MAC address, so A can send
directly to C anyway.

Once again it is because Host A will never broadcast an ARP request.  Hosts 
only broadcast ARP requests when it is on the same network.  The exception 
to this would be if you did not configure Host A with a default gateway in 
which case I believe it would just throw out an ARP request, but I don't 
think this would be the best practice.

Well if I were you, the first thing I'd be looking at is getting a boot rom

similar to what you've posted with a 2509 that some clever buggar tried to
do with 9.1 boot roms , AMD flash , and an IOS upgrade.
(Need I say more?) Cisco are quite happy to provide you with as many as six
sets of boot roms per customer , all you have to do is quote the serial no#

There is a slight anomoly however ,  whenever I contact my case manager
here, for some strange reason he always sends six of everything even if I
only need one. (Maybe they fit into the boxes that way?)

RE: why is routing needed with VLANs - ARP? - follow-up


I think that Peter Van Oene hit the nail on the head (and confirmed my

   " ...  More specifically, which applications can work in a unicast
only
world?  Do you intend on statically mapping all your IP to MAC
relationships on node by node basis since ARP no longer works as a
discovery mechanism?

Thinking about this stuff leads to the understanding that

is a fundamental communication tool in today's networks and one
cannot
eliminate its use without creating a major disturbance.

Your understanding of VLAN'ing as a very simple technology is on the
money however.  Its simply a way to create two broadcast domains

OK.
I must be brain dead, today.
   (and, yes, Chuck, I *have* had my morning dose of Diet Coke :)
and, yes, I know, "What's so special about 'today' "?
   )
As far I can understand it so far, about the only benefit that I see
from VLANs is reducing the size of broadcast domains.

Suppose that I have a switch in the closet with one big flat address
space (well, it couldn't be that big with only one switch, now, could
it ?).  Then someone says,
  "You know, we're getting a lot of blah-blah broadcast traffic.
   Let's VLAN.
  "
OK, fine.  We VLAN and put whatever services in each VLAN that are
required to handle the broadcasts (e.g., DHCP service).  So, now the
switch doesn't send broadcasts outside a particular VLAN.

But, what's so magic about a VLAN that the switch also decides not to
send unicasts outside a VLAN.   Before the VLANs, the switch maintained
a MAC table and knew which port to go out to get to any unicast address
in the entire space.  So, why can't it continue to do that after we
arbitrarily implement some constraint on broadcast addresses?
It seems to me that the same, exact MAC table, with an additional VLAN
field would not require that restriction.  If it's a broadcast, send the
packet only out ports with a VLAN-id that matches the source port's
VLAN-id.  If it's a unicast, handle it just like we used to.


Similarly, even if we have 5 switches, I just don't see the requirement
that we (as switch-code designers) must block unicasts and resort to a
routing requirement.

Even with 500 switches ... well, let's not get ridiculous :)


I feel that there is a simple point that I've overlooked, so I will
continue to RTFM while I await your responses.)

Re: Catalyst traceroute problem

2001-01-17 Thread Luis Ignacio Zas


Obviously your problem is not that the printer doesn't understand pings, 
since you said it replies to them. Since traceroute is not working, it 
means pings are getting blocked along the way.

My hypotheticals:
1 - The Mainframes and the printer are on the same VLAN on the switch and 
other traffic   is not getting routed that specific VLAN.
2 - The switch has some kind of port blocking or security activated on 
certain ports.
3 - One of your routers has an access list configured that is blocking 
traffic or maybe a firewall is blocking the ping.

Hope it Helps

Re: eigrp study question

2001-01-17 Thread Edward Solomon


  3.  what is the igrp algorithm (is it the one on page 257)?  it says
here
  tha tigrp * 256 = eigrp's algorithm, but was wondering, why multiply by
 256,
  and not a different number?

IGRP uses a message format with a 24-bit metric field.

E-IGRP uses a message format with a 32-bit metric field.

That's why you multiply by a factor of 256 to get the E-IGRP value. Same
algorithm, essentially.

RE: crossover or straight cable?


The rule to follow about cross-over or straight
cabling confusion is this :

If you are connecting same layer devices, use a
cross-over cable (as in switch to a switch-layer 2 to
layer 2 or a router to a router -layer 3 to layer 3).

If you are connecting devices from different layers,
use a straight cable ( as in connecting a switch to a
router - layer 2 to layer 3 connectivity).

 A trunk port is simply a port that has traffic from
 more than one VLAN running over it. It is a function
 of the software to combine and split the data. That
 has nothing to do with how the cabling is done.
 If you have a trunk running from switch to switch,
 it
 will be crossover. If you have a trunk running from

I suggest you look for a book entitled "LAN Wiring".  I believe that it's 
now in its second edition.

Thanks for the advice.
The book is indeed in its second edition, not available yet, seems it will be soon and 
will be completely up to date; gigabit ethernet, fiber optics, etc.

RIP--Network command

I was just doing some RIP configs and realized that I knew how to use the
"network" command but was not really sure how it worked. For instance if
there are three routers a,b,c with major nets 10.1.10.x, 10.1.20.x and
10.1.30.x  Each router would need the network 10.1.0.0 correct? Now
supposing router c knew of another major net say the 172.68.x.x through rip
updates Do I need to have the network 172.68.0.0 command on router c or not?
Why? Any clarification on the command would be helpful

funny,, I said the same thing over two months ago.  Good rule to follow.

 Sampy Ren [EMAIL PROTECTED] 01/17/01 10:34AM 
The rule to follow about cross-over or straight
cabling confusion is this :

If you are connecting same layer devices, use a
cross-over cable (as in switch to a switch-layer 2 to
layer 2 or a router to a router -layer 3 to layer 3).

If you are connecting devices from different layers,
use a straight cable ( as in connecting a switch to a
router - layer 2 to layer 3 connectivity).

Hopefully this gives you the concept of the cabling
schema.

Re: RIP--Network command

2001-01-17 Thread Phil Barker


Stu,
   It may be worthwhile to consider that you are the
router. A friend or neighbor has told you that you can
reach another network if you go via a certain
destination point i.e interface address. So this route
you now understand that to get to this network go that
way.

Your job now is to tell your neighbors that you have
this new information so you inform them in your next
network update that this route exists. 

Their is no point in telling the router from which you
learned the new route from, since it told you first,
this is called split horizon.

The answer to your question is that RIP will advertise
the new network for you.

HTH,

Phil.

Debugging a connection

2001-01-17 Thread Andrew Lawrence


I have a Cisco 3600 with a Primary rate card, x21 leased line connection as
well as an ethernet port.

The x21 serves our Internet connection whilst the Primary ISDN is for
dialling in to customers.

I've setup dialer interfaces and IP routes and when I ping the remote router
the correct number is dialled, CHAP takes place and is successful and the
connection is made. But I don't get any response from the remote router. I
know the remote router is working as I've dialled into it using another
router and the pings work.

What things do I need to check to see where the problem lies? There seems to
be a sprinkling of access-list permit commands and 1 dialer-list permit
command. What are these for? If I remove them all will the default mean that
nothing will get through ? 

What sort of debugging commands can I turn on to aid the process?

Any help gratefully received.

Andy

RE: why is routing needed with VLANs

2001-01-17 Thread Peter Van Oene


Just for clarity, VLAN's are a layer 2 concept and IP is of course a layer 3 (please 
do not start with the "but what layer is arp again" :)  

Despite subnets and VLAN's generally happening on a 1:1 basis in a lot of theoretical 
and practical discussions, the two concepts are totally unrelated and altogether 
unaware of each others presence.  An IP host will not detect a node is on another VLAN 
and hence send to the gateway, it will detect a node is on another subnet.  It doesn' 
t really care if the node is in the same broadcast domain or halfway around the world, 
if its not on the network, its sent via the gateway.  This is very strict behavior.  
Nodes on different IP subnets do not communicate directly in any case without the use 
of an intermediary, layer 3 device.  

VLANs as a concept are of trivial complexity.  VLAN membership, particularly dynamic 
membership along with protocols like 802.1q, ISL, PVST etc that leverage and support 
VLANs do offer some element of challenge and opportunity for best practise designs.  

I just felt that the line between VLANs (broadcast domains) and IP subnets was getting 
somewhat blurry when it really shouldn't be.



*** REPLY SEPARATOR  ***

On 1/16/2001 at 10:19 AM Curtis Call wrote:

Keep in mind that seperate VLANs will be seperate subnets.  Which means 
that by default a host will encapsulate any IP packet destined for a 
different VLAN within an ethernet packet with a destination MAC address of 
the default gateway.  So a layer 2 switch will never get the chance to try 
and "switch" between VLANs since everytime a host needs to get to a 
different VLAN (subnet) it will just send a packet to the router which is 
on the same VLAN in order for it to be routed.

Subject: why is routing needed with VLANs


OK.
I must be brain dead, today.
(and, yes, Chuck, I *have* had my morning dose of Diet Coke :)
 and, yes, I know, "What's so special about 'today' "?
)
As far I can understand it so far, about the only benefit that I see
from VLANs is reducing the size of broadcast domains.

Suppose that I have a switch in the closet with one big flat address
space (well, it couldn't be that big with only one switch, now, could
it ?).  Then someone says,
   "You know, we're getting a lot of blah-blah broadcast traffic.
Let's VLAN.
   "
OK, fine.  We VLAN and put whatever services in each VLAN that are
required to handle the broadcasts (e.g., DHCP service).  So, now the
switch doesn't send broadcasts outside a particular VLAN.

But, what's so magic about a VLAN that the switch also decides not to
send unicasts outside a VLAN.   Before the VLANs, the switch maintained
a MAC table and knew which port to go out to get to any unicast address
in the entire space.  So, why can't it continue to do that after we
arbitrarily implement some constraint on broadcast addresses?
It seems to me that the same, exact MAC table, with an additional VLAN
field would not require that restriction.  If it's a broadcast, send =
the
packet only out ports with a VLAN-id that matches the source port's
VLAN-id.  If it's a unicast, handle it just like we used to.


Similarly, even if we have 5 switches, I just don't see the requirement
that we (as switch-code designers) must block unicasts and resort to a
routing requirement.

Even with 500 switches ... well, let's not get ridiculous :)


I feel that there is a simple point that I've overlooked, so I will
continue to RTFM while I await your responses.)

How good are 4000s for the lab?

2001-01-17 Thread Francisco Muniz


I see many on ebay, some cheaper than 2500s. And you can mix and match
interfaces. I'm trying to make a good lab for around $6000 (about the
max I can get my hands on without doing anything illegal). OTOH, maybe I
should rent lab time. The money would get me about a full month at a
minimum of a very good (and expensive) lab. What do you think? I'm
trying to get the # by june.

2001-01-17 Thread Eric Fairfield


I used four 4000's each with enet, tr, and wan.  Worked fine for me.  Of
course I had quite a few 2500's also.  The biggest thing is that the 4000
only supports 16MB of RAM.  This will prevent you from loading 12.1 type
code at times.  12.1 with 56bit encryption would not load.  12.0.7 worked
fine though.

RE: why is routing needed with VLANs


And, I suppose (more idle speculation, Bob??) ...

If you had two sets of devices and no need for communication between
those sets, you could theoretically create 2 VLANs with addresses all
within the same subnet (ignoring any possible restrictions in a
particular piece of switch code).

Even then, you *would* be able even to talk TCP/IP between those VLANs,
if unicasts were forwarded by the switch outside the VLAN (and you were
willing to create manual, permanent ARP entries where needed) --
but, they're not.  BTW, is this a CISCO-specific implementation
or are there VLAN RFCs that prescribe necessary behavior.

Subject: RE: why is routing needed with VLANs


Just for clarity, VLAN's are a layer 2 concept and IP is of course a
layer 3 (please do not start with the "but what layer is arp again" :)

Despite subnets and VLAN's generally happening on a 1:1 basis in a lot
of theoretical and practical discussions, the two concepts are totally
unrelated and altogether unaware of each others presence.  An IP host
will not detect a node is on another VLAN and hence send to the gateway,
it will detect a node is on another subnet.  It doesn' t really care if
the node is in the same broadcast domain or halfway around the world, if
its not on the network, its sent via the gateway.  This is very strict
behavior.  Nodes on different IP subnets do not communicate directly in
any case without the use of an intermediary, layer 3 device.

VLANs as a concept are of trivial complexity.  VLAN membership,
particularly dynamic membership along with protocols like 802.1q, ISL,
PVST etc that leverage and support VLANs do offer some element of
challenge and opportunity for best practise designs.

I just felt that the line between VLANs (broadcast domains) and IP
subnets was getting somewhat blurry when it really shouldn't be.

Processor Parity Memory Error.

2001-01-17 Thread James Haynes


Hi all,

We recently (yesterday) had a Cisco 7507 start acting funny in the middle of
the night (when else) and a few hours later rebooted itself. As this router
has never given us any problems before we were a bit concerned. Looking at
the log files and some show commands located what appeared to be a processor
parity memory error. Not knowing what to make of this I opened a case with
TACS and eventually received the reply shown below after sending the show
tech-support file and log file to them.

My question is:

If the event represents a faulty memory module is there any way to monitor
for such a problem beginning to occur again? Something perhaps in CiscoWorks
or some process that can be monitored. As this problem appeared to occur
over an entire night I was thinking you may be able to see it coming. If it
truly was a random event then we shouldn't have to worry about it. Thx for
any suggestions.


***
Reply from TACS:

"The router crashed due to a processore parity memory
error (PMPE).  In a router that uses parity checking, each byte of data
stored in memory has an associated parity bit.
If the sum of the bits violates the even (or odd)  arity rule, the basic
input-output system halts the router with a message
like "processor memory parity error". While having the router halted is
certainly undesirable and is at the very least
inconvenient, it is good news relative to some of the imaginable
alternatives if the error were to have
gone undetected.

This could be due to several things:

* Faulty Memory
* Transient Memory Error.

Faulty memory would cause more than one crash, so if the router has crashed
several times for this error
it is most likely the cause of your problem. Howeve, if the parity crash
happens no more than 1 time per month
than the problem is most likely caused by an electrical transient error
(Alpha particles) which are
naturally occuring high energy particles that can strike parts of the
silicon in DRAM transferring energy to them.
This can cause a bit to change - hence a parity error. This is is not a
hardware failure.

Due to the fact that this is very hard to define, my recommendation is to
monitor the router for further
issues. If the crash occurs again or has happened several times in the past,
then the memory in the router
needs to be replaced (on RSP)."

Multicast: Router and Switch locations


Currently reading about Multicast, which I have not any experience with yet.

If you have a small simple LAN with 1 fileserver, 10 workstations and 1
router to the Internet:


INTERNET---[router]---[switch]---[fileserver  10 workstations]


In order for that fileserver to send multicast data to participating
workstations without changing the topology, I would have to setup the router
with IGMP and CGMP, so the workstation could tell the router that it joined
a group, and the router could then inform the switch with CGMP about that
workstation. The fileserver would now send multicast data and the switch
would know which interface(s) to forward it out to.

Since the server and every workstation has their own connection to the
switch (and hence has their own individual collision domain), would I be
right in assuming that it would not improve the situation to add an
additional router to act like a filter between the switch and the server?


INTERNET---[router]---[switch]---[10 workstations]
 |
  [router2]
 |
 [fileserver]


Also, will we see multicasting work without a router or an rsm but only with
a switch in the future (I know that switches don't understand IGMP)?

Ole

Access Lists on a Cisco 7200

2001-01-17 Thread Scott S.


Our WatchGuard FireBox seems to be getting overloaded by the number of
NetBios packets it is denying.  We are thinking that it might be a good idea
of blocking these at our router instead.  It is a Cisco 7200 with a pretty
light load.  Does this sound like a sensible idea?  If so I was thinking the
following rule would be appropriate:

access-list 101 deny any 195.50.79.0 eq 137


Is this correct, or am I way off?


Thanks in advance for any replies.

RE: Multicast: Router and Switch locations

2001-01-17 Thread Bob Johnson


In a simple setup like (where you are not actually routing multicast traffic
but would like CGMP to control multicast traffic at the switch check out:

http://www.cisco.com/warp/customer/473/38.html

It can be done as long as you have 1 router interface in the VLAN. The
secret is to not enable multicast routing at a global level but enable PIM
on the interface. This will then allow CGMP packets to be sent from the
router to the switches. The switches will then not pass multicast groups to
any port that has not received IGMP packets requesting such groups

Another choice would be to use IGMP snooping if your switch supports it...

You don't need a router for multicasting if everything is in a single
broadcast domain The multicast server will  just spit out data, the
clients will receive it... The clients will send IGMP requests but since
everything is in a single VLAN they are not needed

Re: CCNP-BCMSN

2001-01-17 Thread Seth Wilson


Chan,

It's been quite a while since I've taken BCMSN, but I don't believe there
were any fill-in-the-blank CLI questions, though I believe there were a few
multiple-choice ones.  VLANs and VTP operations, spanning-tree and MLS were
covered pretty thoroughly on the exam.  I recall few to zero questions about
HSRP, and very little on multicasting, though you should be familiar with
the basic operations and commands associated with each.  There is the usual
product selection associated with all the CCNP exams.  In addition, there
are quite a few management and troubleshooting questions about LEDs,
configuring the switch, etc.  Overall not too difficult an exam if you read
through it carefully.  Good luck.

~Seth~

Problems dialing into cisco 801

2001-01-17 Thread Neil Bennett


Hi,

Im stumped with this problem. Got a 801 configured with dialer profiles,
there are 2 dialers set up, they both work fine dialing out. The problem is
when the other routers (a shiva and a 3620) try to dial in. I can see a
connection coming in, but the 801 just seems to drop the call. With debug
ppp authentication turned on i get nothing, so it doesnt even get to that
stage. I have also debugged ppp negotition but all i get very little
information from that. LCP comes up.then comes down again. It almost
seems like the 801 is rejecting the calls, but i cannot see why.

This is part the config from the 3620:

interface BRI1/0
 no ip address
 encapsulation ppp
 dialer pool-member 1
 isdn switch-type basic-net3
 isdn send-alerting
 ppp authentication chap callin

interface Dialer1
 ip address xxx.xxx.xxx.xxx 255.255.255.252
 encapsulation ppp
 dialer remote-name cisco801
 dialer pool 1
 dialer string xx
 dialer-group 1
 ppp authentication chap callin

From the 801:

interface BRI0
 no ip address
 no ip directed-broadcast
 encapsulation ppp
 dialer pool-member 1
 isdn switch-type basic-net3
 ppp authentication chap callin
!
interface Dialer0
 ip address xxx.xxx.xxx.xxx 255.255.255.252
 no ip directed-broadcast
 encapsulation ppp
 dialer remote-name cisco3620
 dialer string xxx
 dialer pool 1
 dialer-group 1

I don't know where my brain is today, for some reason I was thinking that
the CLI was the command set associated with the low-end switches.  You WILL
need a pretty extensive knowledge of CLI commands for fill-in-the-blanks, as
well as some router config commands.  The IOS switch commands are the ones
that are covered less thoroughly.  If you don't have access to a 5xxx
switch, like I didn't, do a lot of lookup on CCO about the commands, and

That's what I did anyway, and it paid off.  I actually prefer

Woah!  Make sure you do a permit any any first.  Remember that there is an
implicit deny any at the end of your access list!  There shouldn't be a
problem stopping NetBIOS at the router, a better example might look like
below.

Ex.:

access-list 101 deny udp any any eq 137
access-list 101 permit any any

RE: Multicast: Router and Switch locations

2001-01-17 Thread Evan Francen


You would not have to setup the router with ip multicast-routing (IGMP),
unless the multicast server and clients are in seperate VLANs.  The
workstation doesn't need to tell the router that it joined the group when
the server and clients are in the same VLAN.  The server will just send the
multicast data to a specific multicast group (224.0.0.1 - 239.255.255.255),
then the clients listening for that group address will respond.  Switches
forward mulicast data out all ports except the one that the data was
received on.  

I would think that with 10 clients on the switch, it would be overkill to
add another router.  Multicasting will work fine with only a switch, the
traffic will just be forwarded through all ports.  If you have separate
VLANs, then turn on multicast routing on the switch, choose your PIM mode,
and enable CGMP.  The router uses CGMP to aid the switch in building the CAM
table for multicast traffic.

HTH,
Evan

Subject: Multicast: Router and Switch locations


Currently reading about Multicast, which I have not any experience with yet.

If you have a small simple LAN with 1 fileserver, 10 workstations and 1
router to the Internet:


INTERNET---[router]---[switch]---[fileserver  10 workstations]


In order for that fileserver to send multicast data to participating
workstations without changing the topology, I would have to setup the router
with IGMP and CGMP, so the workstation could tell the router that it joined
a group, and the router could then inform the switch with CGMP about that
workstation. The fileserver would now send multicast data and the switch
would know which interface(s) to forward it out to.

Since the server and every workstation has their own connection to the
switch (and hence has their own individual collision domain), would I be
right in assuming that it would not improve the situation to add an
additional router to act like a filter between the switch and the server?


INTERNET---[router]---[switch]---[10 workstations]
 |
  [router2]
 |
 [fileserver]


Also, will we see multicasting work without a router or an rsm but only with
a switch in the future (I know that switches don't understand IGMP)?

Thanks,

I still have some token ring cards.  If anybody is still interested shipping
averaged 5.75 for a pair.  If not they are hitting the trash can at the end

P.S. International orders were running about 50.00.  (A little rich for my

Re: Patch Panels


Hi,

Patch panels are the panels that exist in wiring closets.  I a number of places (most 
of where I work.) the term wiring closet is used for the place where the patch panels 
are housed if at all.

Basically a ptch panel is a panel that allows you to put cables from one socket to 
another.  For example you might have 3 outlets to a workstation area,  these would 
come back to a patch panel in a wiring closet from there one socket might be plugged 
into a switch or hub another might go into another patch panel connecting two wiring 
closets then onto a phone system, a different switch (for redundancy purposes) or what 
ever.

Hope this helps

 Could someone please elaborate on patch panels, or point to some

 I understand the use of panels when you have your switch/router in,
 say, rack1 and your devices in rack5, you then have patch panels in
 rack5 hardwired over to rack1.
 I'm missing the practicality in other cases:
 Your router/switches are in rack1 and you have them hooked up to patch
 panels also in rack1. Why not bypass the patch panels in this case?
 Wiring closets; you have hubs in the closet, wired to patch panels in
 the same closet. Again, why not bypass the panels?
 When a workstation needs to be "punched down", does that mean you need
 to hardwire a port on the patch panel to the hub, then run a line from
 workstation to the patch panel? Any info available on the "punch down"
 methodology?
 
 Any clarifications greatly appreciated.

Re: Catalyst traceroute problem

2001-01-17 Thread Priscilla Oppenheimer


Cisco and Unix don't use ping for traceroute.

Like Microsoft, Cisco and Unix depend on intermediate routers to decrement 
the TTL and send ICMP TTL Exceeded. But unlike Microsoft, Cisco and Unix 
send a UDP frame to a high UDP port, starting with 33434. They rely on the 
end station sending an ICMP Destination Unreachable/Port Unreachable, which 
doesn't always work because some end stations don't send it.

RE: crossover or straight cable?


Hi,

NO

For a start the cable is a layer 1 device as are the electrical properties of the 
ports so the theory of different layered devices does not hold up.

Secondly a layer 2 device cannot talk directly to a layer 3 in another machine.  Layer 
2 can only talk to layers 1  3 in the device it is in.  Then layer 1 passes the data 
(electrical pulses) to the layer 1 on the next device.  If the layer 2 passes the data 
(a frame) to layer 3 then layer 3 decides on where to pass it up the protocol stack 
only if the layer 3 sees it as valid.

BASIC COMMS (similar to a normal conversation between 2 people)

A talker speaks to a listener via some medium (air, telephone wire, sign language) a 
protocol must be agreed to.  Maybe English, Chinese or sign language.  If someone 
spoke to me in sign language thay may as well speak to me in Chinese as I don't 
understand either nor would sign language be appropriate over a phone.

Each talker must have a listener if you have two devices that are the same thier 
electrical paths will be the same therefore you need a crossover.  Switch to switch 
(both layer 2 SO WHAT), Switch to Hub (Layer 2 to Layer 1) both are similar 
electrically in there port design (this was deliberate to make connections to PC NIC's 
and routers etc simple else would would need a NIC for a Hub and a different one for a 
Switch) A switch to a hub requires a crossover.  

A router or PC to a switch or hub.  The ports are different electrically a straight 
cable will work.  A router to a PC are similar electrically these need a crossover.

X cross over simply puts the send signal to a receive on similar port types nothing 
more flash than that.  The secrete is cables are a part of layer 1 and have nothing to 
do with the upper layers.

I put a spread on this and the pinouts a couple of weeks ago.

Hope this makes it easier.

 The rule to follow about cross-over or straight

 If you are connecting same layer devices, use a
 cross-over cable (as in switch to a switch-layer 2 to
 layer 2 or a router to a router -layer 3 to layer 3).
 
 If you are connecting devices from different layers,
 use a straight cable ( as in connecting a switch to a

 Hopefully this gives you the concept of the cabling

  A trunk port is simply a port that has traffic from

  If you have a trunk running from switch to switch,

RE: why is routing needed with VLANs


Right.  It all depends on how the tables are managed and the particular
code implementing VLAN.  The ICND book specifically says unicasts are
*not* forwarded outside of the VLAN, so I conclude that my little
scenario obviously wouldn't work on a CISCO.

But, if the MAC tables *were* VLAN-commingled and forwarding outside
VLAN were permitted, it seems that it *could* work on a single switch.

E.g., if I, in VLAN2, send a packet with a destination MAC in VLAN3,
the switch *could* see which port the target MAC is on and forward it.
Now, if the target MAC weren't in the table at all, then it might
forward only out VLAN2 ports, so I couldn't initiate a conversation
until the switch actually learned which port this particular target is
on.  But if the switch *did* forward unknown-destination-MAC packets to
*all* unknown ports, even VLAN3, then 

Now, let's think about the above scenario with multiple switches and
trunking.

No.  Let's not ;)

Subject: RE: why is routing needed with VLANs


In my experience, there exist some bridge table variations from vendor
to vendor that might impact on your unicast forwarding idea.  I'm not
positive what Cisco does and maybe someone can comment, but I have seen
many implementations that build separate MAC - Interface tables per
VLAN, thus fully isolation traffic from one VLAN to the other(s).

In theory, VLAN technology should involve complete separation of traffic
from VLAN to VLAN and not simply isolation of all 1's broadcasts.  I
expect this is exactly the case in most vendors implementations but
never really tried to verify it.  Keep in mind that again, VLAN
technology was not solely designed for IP networks.

To you point below, the 802.1d compliant switch is a layer 2 device and
does not decode layer 3 headers and thus it doesn't matter what
addresses (be they IP or otherwise) you assign to whatever devices you
chose to attach to it.  As far as documentation goes, I haven't seen
much outside of 802.1q document ion which exists I believe as a subset
of a revised 802.1d spec out of the IEEE.  The basic functionality to me
isn't reflective of something one would need a document for, given RFC's
and such are designed to enable multi vendor inter operability among
other things.

If you had two sets of devices and no need for communication between
those sets, you could theoretically create 2 VLANs with addresses all
within the same subnet (ignoring any possible restrictions in a
particular piece of switch code).

Even then, you *would* be able even to talk TCP/IP between those VLANs,
if unicasts were forwarded by the switch outside the VLAN (and you were
willing to create manual, permanent ARP entries where needed) --
but, they're not.  BTW, is this a CISCO-specific implementation
or are there VLAN RFCs that prescribe necessary behavior.

Subject: RE: why is routing needed with VLANs


Just for clarity, VLAN's are a layer 2 concept and IP is of course a
layer 3 (please do not start with the "but what layer is arp again" :)

Despite subnets and VLAN's generally happening on a 1:1 basis in a lot
of theoretical and practical discussions, the two concepts are totally
unrelated and altogether unaware of each others presence.  An IP host
will not detect a node is on another VLAN and hence send to the
gateway,
it will detect a node is on another subnet.  It doesn' t really care if
the node is in the same broadcast domain or halfway around the world,
if
its not on the network, its sent via the gateway.  This is very strict
behavior.  Nodes on different IP subnets do not communicate directly in
any case without the use of an intermediary, layer 3 device.

VLANs as a concept are of trivial complexity.  VLAN membership,
particularly dynamic membership along with protocols like 802.1q, ISL,
PVST etc that leverage and support VLANs do offer some element of

Re: wrong subnet

2001-01-17 Thread Gareth Hinton


How does this seem as a reason for making router/network equipment addresses
the lower addresses.

Subnet is 192.168.16.0/24 with router 192.168.16.1
Subnet needs to expand to 192.168.16.0/23 (So router remains in a sensible
location at lower end as opposed to stuck in the middle of subnet as it
would be at 192.168.16.254)

Similarly:
Subnet is 192.168.16.0/24 with router 192.168.16.1
Subnet needs to shrink to 192.168.16.0/25  or /26 or /27 etc
No matter how far you shrink the subnet, the router remains in the subnet.
If it had been 192.168.16.254 it would have had to change to .126, .62, .30
respectively.

 One place I worked placed all their routers at the dot 100 address.
Printers
 were all dot 1 through 10. All other clients were DHCP. Kind of a pain to
 set up DHCP scopes initially, I suppose.

  Their security folks did this deliberately, the idea being that since
 everyone numbers their routers as either dot 1 or dot 254, that's where
 hackers ( internal, in this case, because it was al private addressing )
 would be looking. It would be easier for the snoop software to discover
 someone trying to telnet to a couple hundred addresses than it would be to
 discover someone attempting to break into just a couple of addresses.

 Well, that's what they said, anyway.

why pri call failed

2001-01-17 Thread jenny . mcleod


It looks like your service may not be properly active.
Usually, if you have a PRI service that is active but has no calls, debug
isdn q921 will give you something like
ISDN Se1:15: RX -  RRp sapi = 0  tei = 0 nr = 0
ISDN Se1:15: TX -  RRf sapi = 0  tei = 0  nr = 0
ISDN Se1:15: TX -  RRp sapi = 0  tei = 0 nr = 0
ISDN Se1:15: RX -  RRf sapi = 0  tei = 0  nr = 0

You're exchanging SABMEs and UAs between your router and your switch
instead, which doesn't look healthy.
I came across one of our links recently that showed as happy with 'show
isdn status', but debug isdn q921 showed a similar output to yours - it was
exchanging SABMEs and UAs instead of RRs (and it wouldn't accept or make
calls, either).
When I shut and no shut the controller and D channel, it didn't fix the
problem, but at least the router worked out it was broken and reported it
as such with 'show isdn status' :-)

RE: RIP--Network command

2001-01-17 Thread Chuck Larrieu


The network statement is used on the originating router.

For the classful routing protocols, the network statement should use the
classful address. In the case you mention, 10.0.0.0.
This means RIP, RIPv2, and IGRP.  EIGRP used to be that way. Not sure if
that changed in the 12.x IOS releases.

For incoming route notifications, routes are compared to what is already in
the routing table. If it's not there, then the incoming route is installed.
No need to have network statements to cover al possibilities.

Another way to put it is that the network statement has local significance
only.

2001-01-17 Thread Craig Columbus


Do a "debug isdn events" and "debug isdn q931" on the 801.  Look for a 
cause code...it'll look something like "Cause i = 0x8090 - Normal call 
clearing", though your message is likely different.  Check Cisco's web 
site, http://www.cisco.com/warp/public/112/chapter17.htm, for cause code 
definitions and more information.  Shoot me an e-mail if you need more 
assistance.

Hi,

Im stumped with this problem. Got a 801 configured with dialer profiles,
there are 2 dialers set up, they both work fine dialing out. The problem is
when the other routers (a shiva and a 3620) try to dial in. I can see a
connection coming in, but the 801 just seems to drop the call. With debug
ppp authentication turned on i get nothing, so it doesnt even get to that
stage. I have also debugged ppp negotition but all i get very little
information from that. LCP comes up.then comes down again. It almost
seems like the 801 is rejecting the calls, but i cannot see why.

This is part the config from the 3620:

interface BRI1/0
  no ip address
  encapsulation ppp
  dialer pool-member 1
  isdn switch-type basic-net3
  isdn send-alerting
  ppp authentication chap callin

interface Dialer1

  encapsulation ppp
  dialer remote-name cisco801
  dialer pool 1
  dialer string xx
  dialer-group 1
  ppp authentication chap callin

 From the 801:

interface BRI0
  no ip address
  no ip directed-broadcast
  encapsulation ppp
  dialer pool-member 1
  isdn switch-type basic-net3
  ppp authentication chap callin
!
interface Dialer0

  no ip directed-broadcast
  encapsulation ppp

Thanks for any help,

Cannot Access BRI port ( DAM !! )

2001-01-17 Thread Aditya


hi all,

This is a veired situation for me. Im having a 7200 with a lot of bri =
ports. One of the ports(BRI 3/4) is shutdown administratively. When I =
use show config command it dosent display the statistics of that port, =
nor am I able to enter into the interface configuration mode (on the =
global config prompt I used " int bri 3/4 " ), it gives the error saying =
" cannot access ISDN channels ". Im "able" to do the same for all the =
other ports except this one using the same command.

Interesting thing here is I get an output when I say " show int bri 3/4 =
". Below is the output !!

sh int bri3/4

Re: Error Message


Hi,

Late collisions will often occur when you have one end at full duplex the other at 
half duplex.  The full duplex will keep sending even after the poor little half duplex 
has started to transmit.  This interupts the half duplex well into its transmission 
and whammo a late collision.  This also often occurs when autonegotiate is set on a 
switch and all appears to be fine.  I have found that to configure both ends manually 
is best.

Just a thought

Re: Error Message

2001-01-17 Thread Aditya Kedia.



I agree !!

Late collision occurs when the packet is not even completely transmitted
from the routers interface. It may even be a topology problem. I suggest you
to also have a check on the cable length specifications and the network
diameter to see if they meet the standards.

Re: OSPF: Master / Slave relationship

Hi ,

I agree with priscilla , but doesnt this master/slave relationship change
after the slave had sent its dd packets to the master then the master
becomes slave and sents the dd packets?

It's bidirectional communication. They both send and acknowledge DD 
packets, but the designation of master versus slave doesn't change. There's 
no need for it to change.

I think it's kind of cool that they throw together this ad-hoc 
single-purpose connection-oriented protocol to exchange their databases and 
then don't use it again.


can you send me the report of ur sniffer priscilla cause i havent yet been

Do you have a Sniffer? I use Sniffer Pro 3.0 from Network Associates. I 
also use EtherPeek 4.0. Both show database description packets quite well.

If you are really a glutton for punishment, you can look at it as text here:

http://www.priscilla.com/ospfinit.html

With some work you will be able to figure out what's going on. I had two 
OSPF routers [10.0.60.2] and [10.0.60.1] connected via a shared Ethernet 
network. These routers were in turn connected to other networks.

Which one becomes master and why?

Note that the routers are already aware of each other's existence but have 
not become fully adjacent when the trace starts. I only saved after they 
had already sent hellos to each other.

Priscilla Oppenheimer [EMAIL PROTECTED] wrote in message

  I don't think the master/slave business is related to DR and BDR. It has
to
  do with neighbor adjacency and establishing the protocol for exchanging
the
  link state database.
 
  After initializing, two neighbors establish bidirectional communication
and
  then enter the ExStart state. In this state, the routers establish a
  master/slave relationship and determine the initial database description
  (DD) sequence number.
 
  At first both neighbors will claim to be the master by sending an empty DD
  packet with the Master/Slave (MS) bit set to one. The neighbor with the
  lower Router ID will become the slave and will reply with a DD packet in
  which the MS bit is zero and the DD sequence number is set to the master's
  sequence number. This DD packet is the first one with actual data, that
is,
  LSA summaries.
 
  The routers then know who is the master and who is the slave and enter the
  Exchange state where they synchronize their link state databases.
 
  When I first looked at all of this on a Sniffer I was pleasantly surprised
  to discover how complicated it is! ;-) It's a little like a TCP 3-way
  handshake.

  Or is it only used on Point-to-Point links, which don't elect DR  BDR?

AHHHHHHHHHHHHHHHHHH 1 point short

2001-01-17 Thread Eric Gunn


I was so nervous about taking the test I only slept 3 hours last night. The 
test isn't too bad and looking back on it I feel I over analyzed many of 
the questions and a handful had me stumped.

1 question just cost me $200 :), Well I am going to try the exam again 
tomorrow if I sleep well, can find the answers to about 10 questions that 
stumped me(For safe measure) and can get a seat.

Thanks everyone for the help,

I may have some questions for the group later if I can not find some 
answers I am looking for.

UDP Fragmentation, Token Ring Keepalives

2001-01-17 Thread Eric Gunn


Could anyone tell me what happens to a UDP packet when it is fragmented?

I assume that it is lost because UDP is a connectionless service, anyone 
have a better explanation?

Also on a Token Ring interface, when you set the keepalives to zero why 
would an interface still be reported as up/down?

Thanks,
