It costs like ... $5000.00 for a piece of 128MB memory module for Cisco 3660. I wonder if it is OK to plug in a third party memory module? Has anyone out there do this? Is it safe to do?

Re: span port [7:8310]
I could see allowing it... But capturing data will only be correct up to 10mb. I guess if the server is slow, then that would not be a problem.

Re: DHCP Requests across VLANs [7:8689]
Start a session with the router and insert a 'ip helper' address. Be carefull though...by default, for whatever reason, cisco thinks netbios broadcast and name resolution along with dns and a few other broadcasts should be forwarded as well. You'll need to manually shut these off via 'no ip forward' example: interface Vlan1 ip address 10.40.48.1 255.255.240.0 ip helper-address 10.70.48.48 ip helper-address 10.70.80.30 ip helper-address 10.70.80.33 ipx network 104048 Then in global config do the following: no ip forward-protocol udp tftp no ip forward-protocol udp domain no ip forward-protocol udp time no ip forward-protocol udp netbios-ns no ip forward-protocol udp netbios-dgm -Patrick >>> "Vlade" 06/15/01 10:44AM >>> There is an easy Win NT solution.

Re: DHCP Requests across VLANs [7:8689]
And no... You need to define 3 scopes one for each vlan/network. The router then unicasts the original broadcast and replaces the network field which originates as 0 with the proper subnet the station is on. The dhcp server then sees a request from the workstation and answers appropriately for that network and the router is all done. -Patrick >>> "Vlade" 06/15/01 10:44AM >>> There is an easy Win NT solution.

Re: Weird Problem [7:33961]
aha! finally somebody else has seen this! hehe Cisco thinks I am being
silly...
try changing the encapsualation on the 'remote' side to frame-relay ietf or
just frame-relay depending on what your end is currently set up as...then
switch it back...if it doesn't work so the same for the 'local' side...
I personally think it's an issue with memory problems on cisco
equipment...sometimes the configs get stuck in space somewhere not in
running or start-up...just out there in some lonley bits and bytes
anyway..after a while of switching the two sides around, you should sync up
on an encapsualation and vavoom
I know it seems illogical but hey... why have a 6th sense if you don't
use it? :)
>>> "Ali, Abbas" 01/31/02 04:53PM >>>
I have a network corporate side is connected to four branch offices with
full T1 and branches are also connected to each other through Frame-Relay in
a full mesh topology as a backup.
Everything is working fine, all the branches have installed the preferred
route through T1 link to reach the corporate network and other sites. Just
to confuse you I have a DHCP server running at the corporate as well as one
of the branch sides. All the branches have a IP helper address pointing to
a DHCP server which is running on a branch office. In other words, traffic
goes to the corporate first then from there go the branch office for dhcp
lease ip address and logon to a windows 2000 domain. It is just a temporary
solution. Eventually all branches will be pointing to the corporate office
through wins or ip helper address for logon to a windows 2000 server.
Here is the issue, one of the branches even though is going through a
preferred route through T1, all the windows hosts will not even boot up and
stuck in a black screen mode if Frame-Relay link is up which is S0. When I
say up it means that is ready to take over incase of the primary link which
is Point to Point fails. As soon as I shut down the S0 interface for
Frame-Relay link, and then boot the hosts they boot fine and also logs on to
the windows 2000 domain. I even made sure that the branch is installing the
preferred route through T1 link and will only go through FR cloud if primary
link goes down.
I can't figure it out how Frame Relay interface can possibly conflict with
this problem. Other branches are working fine with being Frame-Relay
interfaces are up.
Does anyone have a clue? All the help will be appreciated.

Ali

Re: CCIE starting pay [7:33899]
exactamundo!
>>> Guy 01/31/02 03:34PM >>>
A CCIE With no work experience
I think most employers would shy away from that! A CCNP, or CCNA possible,
but CCIE... Im not sure. That would be like a Brain surgeon with no work
experience... WHat would you pay him to operate on your brain
Makes you think eh??? I think your best bet is to get a job as a CCNP or
CCNA, get a year or two experience (Minimum) then worry about CCIE. Maybe
work some other certs in there too, like Unix or maybe Microsoft or
something to round you out a bit more and make some opportunities in the
market for yourself... Or firewalls, and or something like tripwire etc...
My point is, If you have a CCNA, CCNP, CCIE, and 50 other certifications
behind your name, and no work experience, poeple are going to know you are a
good test taker, but you will still be starting off at the bottom. With a
salary range of maybe 30-50k But that CCIE is not going to make it 100k no
matter what your cousins brother or whatever told you. All the
certifications are for is to take someone who has the experience, and
skills, and gives them something they can use as proof of their expertise.
It is not for an entry level person to get so they can get a higher start
pay... All that does is cheapen the cert.
Look at the MCSE. Back when I took my MCSE, that cert gave me credibility. I
walked out of every interview with an offer. I could make my own choices. I
took my MCSE after several years of workwith Net systems including Novell,
IBM OS/2, and Microsoft. It was more of a proof of my skill set. Not a proof
I can read Brain Dumps, and hope I will do ok if someone gives me the
chance...
Now days you mention MCSE, and what goes through your mind??? Thats right
Worthless.
Now why is that?
Its because people with no skills heard of someone who became an MCSE, and
started making 70k or whatever... Then that person decided, Hey, I can
do that And found Transcenders etc... Became an M CSE, but cant even
copy files to a floppy
This happened on a large scale, and soon employers were hiring worthless
MCSEs, and were getting frustrated...
Now, in the IT industry, it has become a low level Cert... TO me that ticks
me off. Ive been an MCSE since 96, and mine is prrof of the pudding not
a piece of paper...
Now, Cisco is becoming the same way. Look at how many people are becoming
CCNP...CCNA...etc... How many of those people could configure a medium level
network lab without the directions
How many could trouble shoot their way out of a paper bag
If people dont try to really learn the systems, all certifications will be
no better than a 3rd grade diploma!
sorry for my soap box, just really feel people take these things the wrong
way If people dont wake up, then all of this is for nothing...
I would not be happy spending a couple thousand dollars to get a 3rd grade
diploma

well, if you really need 90mb, then the best thing to do would be to inverse
mux on your end and have the telco muc them on yoru end... (2 ds3's)
then you would have a 90mb frame pipe to bring remote site into.

thanks for your reply. sorry that I didn't make my question clear.
Actually what I want to know is that, if the port speed requirment to every
remote site is 28mb, then the aggregate port speed requirement in central
site would be 84mb. should I order 2 T3 access circuits or 3 at the central
site? if 2, how can i config the 3 DLCI across the 2 T3 circuits? because
there would be 1 DLCI needed to be split between the 2 T3 circuits.
thanks again!

Re: frame relay question [7:34090]

>>> "Chuck Larrieu" 02/01/02 02:34PM >>>
Some telcos have some basic oversubscription requirements, designed more so
that they can sell you more bandwidth than as a real practical requirement.
Here in California, for example, the local telco permits no more than a 2
for 1 oversubscription.
So if you have 20 spokes, each at 256K CIR, then you MUST have a minimum
2.56 megabit CIR at your center ( fractional DS3 or ATM ), for example.
I believe the reasoning is that the telco does not want a lot of calls
complaining about their circuits when the problem is overutilization of
bandwidth. And they want to sell you more, of course. ;->

First of all I would like to thank you who replied to my questions about
VLans and how to set them up.
Second. In the information I have been reading about VLans usually 2
classes of switches are referenced.
The first being a lower model or switch 1900 series. The Vlan setup is
mostly menu driven as I found out from my Cisco instructor in class
yesterday. There were some problems we encountered when setting up a VLan
on this type of switch.
Third. Usually when ever I read about VLans and setting them up it uses a
5000 series switch as a reference, using the OSI command interface.
Does the 4000 switch use the same setup or interface as the 5000?
Does any one know ?
Thank you very much,

You need to block access to the login server IP's.
If I remember it is login.oscar.aol.com. Just nslookup the ips associated

Same process with Yahoo IM, although you have to block about a million
address's it seems like.
Both services change IP's regularly and you will need to periodically check
to see if new address's are brought on line. Be aware that the process of
blocking YIM will sometimes break access to yahoo e-mail servers that are in
the same range as the login servers.
Also,
Be sure to find the Java script client IP address of AOL and block it as
well. I didn't know that it existed until I walked by someone's desk and
they were just a chatting away. Man was I PO'd bout that one.
It is not an easy process to block and keep them blocked. Both services are
evolving and finding new ways around firewalls so you have to stay vigilant
until you can get those that be to press down and say its not authorized and
those using it will be disciplined.

Re: IPX Routing problem-Conclusion [7:34485]

ipx update interval rip changes-only

-Patrick
>>> "Fraasch James" 02/05/02 03:58PM >>>
It is Cisco to Cisco. 7204 to 2600.
'By changing the update interval from 1 minute to 5 minutes you are
preventing the route and server from flapping and thereby keeping your
connection to the server up.'
This is what the Cisco tech said- AFTER I had already put the command in. I
am not sure why it worked either. I would have thought with 1 minute SAP
and RIP advertisements it would be better than 5 save for the amount of
traffic it produces.
I understand 'flapping' in the cable modem sense of the word but I hadnt
seen it happen in this environment. To me, the flapping means that the
cable modem is connecting and disconnecting at random intervals, sometimes
due to incorrect power configurations. But in this sense I am gathering
that it means the route to the particular server flapped. If that is the
case then it would explain why users could intermittently connect to the
server. Then the question becomes, why did the flapping occur in the first
place?

Here's an interesting twist to that question: If your switch/router is a

interfaces as opposed to switchports?
I'm using a 6509 with Native IOS, and I have a server connected to a port
configured as a "switchport". I was able to "monitor" that port on another
port, also configured as a "switchport". I wonder if it's possible to
"monitor" an ethernet port that's being used as a routing interface (i.e.
not a switchport). Time to try it out. too bad that 6509 is a
production box =)

Re: Undocumented iBGP Behavior (Confirmed by Cisco) [7:34521]
ha! Is that allowed?
>>> "W. Alan Robertson" 02/05/02 04:40PM >>>
Folks,
Just to let you know, I ran across what looked like a bug in Cisco's
BGP code... Turns out, this is undocumented new behavior.
We just deployed a pair of 3640s for one of our customers, for
dual-router, dual-homed Internet connectivity. We are taking full
tables from Genuity (AS 1), and Worldcom (AS 701).
Each router was learning 104,000+ prefixes from each of the external
peers, but the iBGP peering was acting really strange. One of the
routers was learning the full table from the other, but the second
router was only taking like 700 prefixes.
When we cleared the internal peer (soft or hard), we could see the
whole table being transferred... It would climb as though it were
going to learn them all, and then as it approached 100,000 prefixes,
it would rapidly drop back down to 700. I debugged the iBGP peer, and
saw it issuing withdrawls for all of these routes.
We opened a ticket with the TAC, and they initially believed it to be
a bug as well. Upon further review, they came back and told us that
this was the desired behavior in the newer code (We are running
12.0(20) on these boxes). In order to conserve memory, and processor,
if an iBGP peer learns that another iBGP peer already has a better
route to a specific prefix, it will issue a withdrawl to that peer
for the prefix(es).
I spent quite a while second guessing what seemed to be a very simple,
straighforward configuration. I have done several near identical
deployments in the past.
I guess the moral is this: If you know your config is correct, and
the router behavior is not what you expect, do not hesitate to call
the TAC.
I hope they are as helpful on Monday, when I call them from the CCIE
Lab in RTP. ;)
Regards...
Alan

Re: Port spanning question [7:34469]
I'm not totally positive because I have never used the inpkts switch on a
monitor command...but I think he might have been referring to the sniffer
being able to send packets out... (say you are using a sniffer, not in
promiscuous mode, and you want to be able to do reverse lookups on ip
addresses sniffed) good theory? :)

>>> "Michael Williams" 02/06/02 03:07AM >>>
We've setup span ports to monitor servers, etc and we never had to issue any
extra commands so that layer 3 (IP) worked properly. I'm "monitoring" a port
right now and the server attached to the port I'm s "monitoring" operates
just fine, IP broadcasts, ping, etc

I'm guessing that Long Distance State Sharing is the use of firewalls with

As you may or may not know, the Pix Failover cable limits the distance
between Pix's at the moment (unless something's changed recently). Can't
remember how long it is exactly (guessing 10 feet).
Don't know the reason for lack of support for stateful http. Possibly large

RE: 3DES [7:34754]
I hope you are not being serious about '3rd party' firewalls I'm not
saying you shouldn't study pix if you want the certbut resume's are much
more impressive the more firewalls you have under you belt. Especially
firewalls that are more capable than pix.
Of course if your company does not plan on using DCOM or any other
proprietery protocols, then pix will be fine.. (although it's still expensive)
be careful with your planning though...pix's security strategy is based on
NATstatic in from a lower level interface and dynamic out from a higher
security interface... (and variances thereof) It does not truly route
traffic like other firewalls... A way around this is the use of NAT 0, but
then even Cisco tac does not reccomend this configuration for highly
utilized interfaces.

slip/arp/proxy arp switch to csu [7:35413]
Ok guys/gals/fellow listers,
I've been doing some research on setting up a slip connection to a csu from
a switch or router. a lot of the cisco TAC refers to the use of term
servers for this but there are some documents on the site that talk about
manualy connecting from a switch or router through the console port.
Is this a sound method for establishing a slip connection you want to stay
in place? Any comments? And does the console port then behave like a
switch port? Will normal ethernet protocols go across? (arp for example)
I'm having to do this without the use of a spare CSU and am just trying to
get some prelim questions answered. thanks!

RE: slip/arp/proxy arp switch to csu [7:35413]
well...this isn't really for controlling it like a console connection. This
is for snmp traps and NNM polling... If I were to do a reverse telnet to it,
that would indeed give me console access but there's no way to spew snmp
traps back to NNM serially. I needto be able to assign sl0 an ip address
and then give the csu a slip address.
A thought beyond my original is that it would have to be from a router and
not a switch. because I am goingto have to route to that slip network.
so...now...any more comments from anyone else? Anyone tried this?
-Patrick
>>> "Daniel Cotts" 02/14/02 12:11PM >>>
First thoughts are that if I needed to connect to a CSU that I'd connect to
its console port. To do that I'd do reverse telnet using the aux port of the
router. Biggest issue would be verifying the pin outs. Might have to build a
custom cable or adapter. HTH

RE: Secret Clearance? [7:4152]
IT took me 6 months to get mine and I almost didn't get it because a friend in high school got busted sometime after graduation for dealing drugs... And even when I did get it, it was interim and took another 4 months before it was perm. -Patrick I think the Navy estimates 50,000 smackers per investigation >>> "Logan, Harold" 02/14/02 01:03PM >>> I disagree. In order to get a clearance, not only do you have to make the right choices, but all of your past and present friends, roomates, and coworkers need to make the right choices too.

RE: Dening telnet access [7:35628]
This is what I am seeing on 12.2(3) (various 2600 series routers)
ACL's do not work except for devices behind the router...ACC's work for the
router it's self.
-Patrick
>>> "Roberts, Larry" 02/18/02 02:17PM >>>
The only way that the access-list applied to the inbound interface ( non-vty
) blocked your telnet is if you were trying to telnet
To an address that was not the directly connected address ( loopback or far
side serial/ethernet )
If you were to telnet directly to the interface that the access-list was
applied to you WOULD get in. Only an access-class applied
To the VTY ports will stop that.

I know it does. I have, even fairly recently, locked myself out of a router

Are you sure the interface on which you applied the access list is the

Re: Should I buy IDS ? [7:36053]
Well...it depends on how secure you want your network!
The size is completely irrelevant... if you own a medical practice with
patient data floating around your network and you only have 10 computers,
with 4 of them offering some type of internet service through the
firewal,etc etc... then I would say yes...ids is important... if you own
jokenetwork.com and you have 50,000 machines trading jokes all day, are you
worried about sombody stealing your jokes? probably not...
If you do decide to implement some type of ids, look at http://www.lids.org/
remember signature based ids are signature based ids regardless of company
and price as long as you have a constant way to update signatures, you
should be fine. To supplement your signature based design, though check out
www.lancope.com ...They have an AWESOME supplement to signature based
systems. Even though there box will trigger on some signature based
attacks, it is not meant to trigger on them as soon as they happenThis
is why I say it is a supplement and not a complete kit.
Of course...a good security policy would help you decide on what you need!
:)

ps. if you run tons of data through your internet connection (45mb plus) or

Re: CISCO INTERNSHIP.....CCIE..... [7:36091]
pay for an internship?
sounds like I am in the wrong business all together... hehe
>>> "Cisco Nuts" 02/21/02 04:54PM >>>
That's right. A CCNA could potentially make more than $50K (with skills
though)
Here is what I don't understand: Jason states that his company is
looking(note) for people while Sean mentions that you do have to actually
sign up(note) for their program which he adds is not cheap??
So basically, looks like people will first have to shell out this huge
dough out of their pocket to get an intership thru this company.

You would want to use both HSRP and BGP in this case. HSRP will solve the
problem of changing the default gateway on the clients when a link fails.
BGP will be used for fault tolerance at the ISP side. Here is a sample doc I

Subject: How to get the activation key for my clone Pix?
Hi Everyone,
After struggling for the past two days, I have
successfully cloned a Pix firewall by using my PC.
I plug the 16MB flash card into the PC's ISA slot
and the PC recognize that it is a Pix flash card
(cost me $400.00). It boots up fine and everything
seems to be in order. However, after the boot up
sequence, it asks me for the activation key. I've
been trying many different possible scenarios without
much success. I even tried to use the activation key
from another Pix firewall but that doesn't work
either.
Anybody know how I can fake my clone Pix with a
fake activation key? By the way,I am running Pix OS
code version 6.1(2). I even tried 5.3(1), 5.3(2),
6.0(1) and 6.1(1) and one of them works. By the way,
the PC has 128MB of RAM and a 16Mb Flash ISA card.
I tried to clone a Pix520.
Please help.

There's nothing that you can't test yourself on with a pair of 501's that will be that dramatically different with 506's, 515's or whatever The difference would be in the permissions or translations, but as long as you understand that difference, I don't see what the big deal is.

Anybody ever used failover on the pix to upgrade hardware with minimal
downtime? I'm wondering what exactly is goign to happen. I want to take
the secondary offline, insert a gig module, then bring it back
onlinewill the difference in hardware cause issues with the config
sync? I then want to bring the primary down and insert a gig module (or
vice versa) Maybe I should bring the primary down first so when I bring it

Re: question about stateful inspection [7:36817]
Well...if stateful inspection is used at layer three..then the device
utilizing this function is keeping track of the session flowing through...
I would think that stateful inspection at the application layer would be
doing the same...(at leastmaybe even extra stuff)
So if you have an smtp session open through a device that had statefull
inspection enabled for the application layer, then it would track the actual
communication and not the session per seof course... It would almost
seem weird to have stateful inspection in the higher levels without layer

Re: Pix NAT - Two to one [7:37179]
what is the overall goal?
>>> Gaz 03/04/02 03:06PM >>>
Hi all,
Has anybody tried NAT'ing two outside addresses to one internal (DMZ)
address on the same port (80) in some way.
Not too difficult to get round, as I can get the DNS of one site changed and
use the single address outside to single inside.
The advantage would be that when the web sites are separated, to two
machines inside, I would like to be able to change the pix settings
immediately rather than change DNS and wait a couple of days for DNS to
propagate.
I'm sure there may be some simple way of doing it, but I couldn't find it
whilst playing about today.
Any ideas welcome.
Thanks,

Not the whole domain - Re: Delete VLAN [7:37254]
you have to pay attention to the CAT you are deleting the vlan fromif it
is in transparent mode, then the vlan, like the book says will be deleted
from the CAT only if it is in client mode, then no changes can be made
VLAN wise on the switch. If it is the vtp server, then removing VLAN 5 will
delete VLAN 5 from that CAT and all the other CAT's in the vtp domain...
Read the quoted text you placed in your email to usIt describes the
process as well as anybody could describe it. Are you havign problems
following/determining what a switch is? (Server, client, transparent)
-Patrick

Hi,Dave,
First, thank you for your answer.
But I really got confused. Pls read the following excerpt
about Deleting VLAN from the book of Cisco LAN Switching
written by Clark & Hamilton :
You can remove VLANs from the management domain using the clear vlan
vlan_number
command. For example, if you want to remove VLAN 5 from your VTP management
domain, you can type the command clear vlan 5 on a Catalyst configured as a
VTP server.
You cannot delete VLANs from a VTP client Catalyst. If the Catalyst is
configured in
transparent mode, you can delete the VLAN. However, the VLAN is removed only
from the
one Catalyst and is not deleted throughout the management domain. All VLAN
creations
and deletions are only locally significant on a transparent Catalyst.
So, according the above words, it just remove the portion of vlan 5 on that
Catalyst
which clear command was executed. Is it right?
>From Woody's answer to my last question :
Vlan 5 will also be cleared on all switches that are configured as
clients as well. Also, any port that is configured on those switches
will also lose their vlan assignment to vlan 5.
I raised another question: if Woody is right, the portion of vlan 5 on the
Catalysts
configured as clients will also be removed, then my question is: Will all
clients
or just clients configured from that server-Catalyst which clear command is
executed
be removed?
Sorry for taking you long time to read my questions.
Any suggestion would be welcome.

Re: Voice over IP [7:37298]
2600 is enough actualy Cisco's vg200 is a modified 2600... (that is what
is used as the voip gateway) That gateway can also function as the call
manager but you lose a lot fo functionallity (it is normaly used as a
back up call manager) Say your call mnager is across a wan link and the wan
link goes down...the 2600/vg200 will act as a temp call manager until the
wan link comes back up, allowing all local calls. And if you bring a
separate T into the 2600/vg200 then it can also route outbound calls if the
wan link is down.
If you plan on using a full featured call manager server, then you will need
to contact cisco for a demo.

>>> "Chris Charlebois" 03/05/02 02:49PM >>>
VoIP does not require a Call Manager. VoIP is just that, Voice over IP. It
does not specify any call features and only extremely limited call
handling. Use of a Call Manager implies IP Telephony, which is an
alternative to PBX switches. IP Telephony includes complex call handling,
call routing, and features like forwarding, transfering, on-hold,
conferencing, etc.
VoIP (and any VoX) can be used as a point-to-point toll bypass solution,
using traditional PBX switches to provide the call routing and other
features. However, for any kind of certification, all you typically need to
do is make a phone ring, which can be done without IP Telephony.

Are you looking to increase lan speed?

use 802.1q mostly because the 2948s don't support ISL. We even trunk the
6509s using 802.1q even though of course 6509s support ISL and 802.1q. But
I don't know which one is better, and I've done similar searches in the past

VLoFR and atm popularity [7:38003]
Cisco support vlan tagging over frame circuits?
I was looking at a Tierra networks router and it was listed as one of it +'s.
Does Cisco even support this? This kinda creeps up even further on the +'s
of atm and how long atm is going to survive.
Other than being capable of joining elans at oen fac. from another, can
anyone even think of why atm still exists? With wdm and all the newer
technology coming around the corner, why is atm still so saught after for
long distance links?

RE: Stacking 3548s [7:38208]
This doesn't mean that you should do this though be careful with
openview... it starts acting squirly when you cluster switches. And issuing
commands from a telnet session to manage 16 switches is flakey at best. Now
if you are not a OV user and you have cisco works installed, clustering is
pretty cool. Still not like having a separate ip on each switch, but decent.
-Patrick
out of curiosity, are you using registered addresses? Or just
ultraconservative on the ip space? :)

Cisco Switch Clustering
Breakthrough Cisco Switch Clustering technology enables up to 16
interconnected Catalyst 3500 XL, Catalyst 2900 XL, and Catalyst 1900
switches, regardless of geographic proximity, to form a single IP management
domain. Cisco Switch Clustering supports a broad range of standards-based
connectivity options and configurations to deliver levels of performance
that are scalable to meet customer requirements. Switch Cluster connectivity
options for the Catalyst 3500 Series XL include Ethernet, Fast Ethernet,
Fast EtherChannel, low-cost Cisco GigaStack GBIC, Gigabit Ethernet, and
Gigabit EtherChannel connectivity. Because the technology is not limited by
proprietary stacking modules or stacking cables, Cisco Switch Clustering
expands the traditional stacking domain beyond a single wiring closet and
lets users mix and match interconnections to meet specific management,
performance, and cost requirements. Catalyst 3500 XL switches can be
configured either as command or member switches in a Cisco switch stack or
cluster. The command switch serves as the single IP address management point
and disburses all management instructions dictated by the network
administrator. Command switches can cluster up to 15 additional
interconnected member switches regardless of interconnection media.

Re: MUX Vs Router [7:38258]
Well, they are two different pieces of equipment that do two different
thingsRouters take traffic from multiple layer 3 networks, allowing
comunication between them. MUX's and DEMUX's take multiple layer 2 segments
and combine them to form one.
now, aside from that, there are vendors that sell "mux's" that route
traffic... such as http://www.tiaranetworks.com
These are routers in every sense of the word that can also aggregate
bandwidth through multiple serial connections.

Re: Packet loss on OSPF LAN [7:38397]
how have you decided that it is ospf? Or have you? And are you losing
packets because every other packet gets forwarded the wrong way?
if both paths out are equal, try monitoring the port that each router is
plugged into on the 6509 and match against your source address and say
icmp... send 100 pings to the end point and see if you see them across each
router... IF so, do they make it back to the 6509? Where do they stop? Do
you have asymetrical routing going on? Is OSPF even funtioning properly?
Are there any other protocols involved? static routes?

I need to tap into the collective brain power of this list. We have 4 7206
VXR's that are all plugged into a Cat 6509 on the same VLAN with two of the
routers tied to different upstream ISPs. When I'm pinging through this
"core" I'm getting packet loss. I don't understand why, since there is not
much of a load. I've checked buffers, CPU, switch utilization... Are there
any special considerations for running multiple OSPF routers on the same
segment.

or not it was done at the modem or the switch. I'm guessing the latter. I
would hate to think I could go out and by any modem I wanted to and change
the way att does business... :)

I just changed services from DSL to cable modem. I have heard from people,
including verizon, that cable is not as secure as DSL becuase it is over a
shared medium. I connected to my cable modem and fired up my packet sniffer.
I did not see anyone elses traffic on the line so i am assuming the bandwith
is shared( a known fact about cable access) but is somehow filtered at the
cable modem(bridge). Does anyone know if this assumption is true and the
inside details of the how data is transmitted over the cable network? A link
to a whitepaer would be great.
thanks

Re: Is cable network really a shared medium?(more info) [7:38718]
on further invesitgation,
Thirdly, and most importantly, DOCSIS provides a feature called Baseline
Privacy. This is a very secure encryption method that protects data while
it resides on the RF plant. That means that even if someone figures out a
way to get all of your downstream traffic from the RF carrier, which is
unlikely, if Baseline Privacy is enabled they still have to decrypt it. A
case could be made that the RF portion of a Baseline Privacy enabled cable
plant is the most secure portion of the net. Remember, however, that
Baseline Privacy only protects your signal while on the RF plant. All
normal precautions for sending data out on the Internet still need to be
obeyed

depending on the carrier, docsis could be implemented...I have not tcpdumped

Re: SNMP Packet question [7:38824]
I think the rrdtool has some of this built into it...it's a great spinoff of
mrtg... (it's bascialy the engine and you do with it as you please
check out this link.
http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/
and look at so of the graphs people are doing there are also some sample
scripts there!

Hello group,
I am trying to write a script in perl to monitor interface errors and total
traffic during work hours. I'm doing an snmpwalk to get the info. I want the
total amount of packets in and out of an interface so I can calculate the %
of errors on the line.
Cisco says on their site : http://www.cisco.com/warp/public/477/SNMP/5.html
that
ifInNUcastPkts (.1.3.6.1.2.1.2.2.1.12) are counts of inbound broadcast
and multicast packets
ifOutUcastPkts (.1.3.6.1.2.1.2.2.1.17) are counts of outbound
broadcast and multicast packets
besides In and Out whats the difference? I thought Ucast meant unicast and
NUcast meant broadcast and multicast.
When queried, every int gives NUcast and Ucast which are different values.
How could Cisco define them as the same.
Is this a misprint?
Lastly I'm assuming that total packets would be the sum of the 2(unicast +
multicast/broadcast).
Is this assumption correct?
ps i don't want ifOutOctets because i want the # of packets not bytes.
thankd

Re: PIX performance problem again ! [7:38955]
I would hate to ask the obvious but are your interfaces showing high error
rates? Are they at half duplex? Are they at 10mb? Is the switch the
inside interface is plugged into stable? what about the router on the other
side?
