RE: Collapsed Backbone [7:41418]

2002-04-15 Thread Ismail Al-Shelh

First of all thanks to Tom , Georg ,Howard and every body.

To be honest me too is surprising with these terms,  anyhow these terms
simplify how to remember the scenarios and all the staff  arround, I do not
know the essential reason with giving  such a  name but i think collapsed
backbone has given this name because the network   confined with one
building,  there is only one switch block ! as the core and distribution
layer combined in one device.

If I am wrong then please correct me.

First, I wonder who comes up with these terms?  Collapsed backbone 
sounds like something that needs the immediate attention of an 
orthopedist or chiropractor, while "router on a stick" sounds like 
something from the Autobiography of Vlad the Impaler.

First key point. The backbone or core device is defined by topology 
rather than product line.  That point being made, it is true that 
Cisco does position products for access, distribution, and core 
applications generally based on the requirements of large 
enterprises.  But a core switch could be quite slow and small, if 
everything else in the network is small and slow, yet still be a 
reasonable design approach.

>single point for monitoring and controlling the network%.

Second point: as defined, it's also a single point of failure.  With 
a campus network large enough to justify a gigabit switch in a core, 
this is a bad idea. It's usually better to plan on at least two 
physical switches that normally loadshare (e.g., switch 1 is the 
primary for odd-numbered VLANs and switch 2 is the primary for 
even-numbered), but either can take over the entire load.

OT: Know of any good internetworking programs? [7:41468]

2002-04-15 Thread Greg Reaume

Hi all,

I am currently a college student that will be receiving a diploma in
Telecommunications Technology (http://www.telecomtech.org) from Sheridan
College (http://www.sheridanc.on.ca) in Dec 2002.  I have decided that I
wish to pursue a bachelors degree and possibly a masters thereafter,
specifically an engineering degree.  After browsing local university program
calendars I find that most programs with any telecommunications content are
generally labeled, "Electrical Engineering with a 'Specialization' in
Telecommunications."  I spoke to my current professors, who both have these
degrees, and they say that the telecommunications content is a joke for the
application in todays market unless you are looking only to deal with layer
1 technologies.

Though my current program has provided me with an exceptional base of
conceptual and technical knowledge, I feel the need to go deeper and truly
understand the engineering detail of all this.  I want to attend a program,
International if I must, that was built from the ground up as an
Internetwork Engineering program.  A program with content focus above layer
1.  I understand that all good engineering programs will contain advanced
math and that all telecommunications oriented programs will contain
electronics and physical layer material, though I do not want this to
dominate the curriculum.  I have found such programs as Internet Engineering
(http://www.uow.edu.au/discover/courses/yr2002/benginternet.html) and
Telecommunications Engineering
(http://www.uow.edu.au/discover/courses/yr2002/cour736.html) in my brief and
mostly futile searches, though only in 1 Australian University, Wollongong
University.

I post this here because I know that there are many knowledgeable and
industry-aware poeple here, some of whom have made quite a name for
themselves in our field.  I figure that with the wealth of knowledge
observing this forum there must be someone, that who themselves or through
their associations, know of 'the' program I am looking for.  I would greatly
appreciate any leads or information anyone may be able to provide.

Thanks for your time,

Greg

PS.  I think this industry is in serious need of some type of educational
search engine.  In the short time I've spent on educational search pages
I've found not one that specifically lists even a category acutely
appropriate for the internetworking field.  I am quite confident, being in a
field related program and seeing the obvious void in this area, that such a
definative resource would be a hit among seasoned academics and
post-secondary students alike, wishing to extend their knowledge.  Just a
thought for anyone up to the challenge.  :)

I have a strange problem.
I have to carry a printer  a different location ( The PC connected to
printer is not  moving , only printer)
The printer must be connected to RS 232 Port of the PC.
So  I will have to carry RS232 signals through Cisco Router.
I mean PC connected to serial port of router and Printer will connect to
the other router s serial port.

Anybody tried this or has an idea ?

Thanks.

Inside Cisco IOS Software Architecture [7:41475]

2002-04-15 Thread Tom Scott

Internals fans,

I'm reading the book, "Inside Cisco IOS Software
Architecture" as background for chapter 7 of the Sem8
(troubleshooting) online CNAP curriculum. If you haven't
read it, I recommend it for anyone who wants to learn about
router components (buffers, memory, processors, switching
fabrics, buses). Even for a non-EE like me it's a good read.

In chapter 7 the authors explain how the 12000 segments
packets into 64-byte cells: 8-byte header, 48-byte payload,
8-byte CRC/trailer. That surprised me, that cell switching
is the foundation of a high-end router. Does anyone know if
this is common among other vendors?

I'd like to browse through some theory books that compare /
contrast various switching technologies, to get a better
idea of the possibilities for the future. Specifically, a
book that discusses fixed-length vs. variable-length
swtiching. Does anyone have a bibliography like that?

Also, would someone who has a 12000 router please send me
the output of the "show controller tofab queue" command. I
want to compare it to Example 7-3 (p. 158). I assume that
one could use the keyword "frfab" instead of "tofab" to get
information on the transmit buffers. If so, could you
provide the output of that command too (sho controller frfab
queue). Does "carving" refer to the carving / assignment of
shared memory?

-- TIA, TT

Might be of Interest - Cisco Support Policy [7:41477]

2002-04-15 Thread Matthew Crane

April 10, 2002

Cisco GBIC Sourcing & Support Policy

We are continuing to receive questions concerning the consequences of Cisco
end users acquiring GBICs (Gigabit Interface Converter) modules from
non-Cisco sourced third parties or directly from GBIC suppliers for
deployment in Cisco routers and switches.

Apparently there is still some confusion on what Cisco's position and policy
is in respect of these third party GBIC's, which is why I would like to
summarize those for you and highlight the main points. I would also like to
take this opportunity to outline what Cisco would expect from you as a
Channel Partner when it comes to you supplying non-Cisco GBIC's together
with Cisco equipment to end users.

Cisco's policy:
Products from non-Cisco sources do not qualify for Cisco support and may not
be compatible with hardware, power, or software requirements. Cisco sourced
GBIC's can be easily identified by the Cisco logo and trademarks on the
label. If a GBIC does not have the Cisco label and trademarks on it, then it
has not been sourced from Cisco and is subject to the conditions outlined
below.

GBIC's acquired through non-Cisco sources will be subject to the following
conditions:

1) Cisco TAC is not under an obligation to support any non-Cisco GBIC
modules;

2) Cisco SMARTnet will not cover non-Cisco GBIC modules;

3) Cisco does not guarantee the performance or results you may obtain by
using a non-Cisco GBIC;

4) In the event that an end user experiences a support issue that Cisco
determines is caused by use of a third party GBIC, Cisco will not provide
warranty support or support under SMARTNet or another Cisco support program
for that issue. On the other hand, where a product fault or defect occurs in
the network and Cisco concludes that the fault or defect is not attributable
to the use of a GBIC installed by our customers or partners, Cisco will
continue to provide support for the affected product under warranty or a
Cisco support program. The nature of the defect or error is the key to
determining what Cisco's support obligations are.

Cisco sources GBIC's from third party suppliers, who agree to follow Cisco
quality standards.  Sometimes, Cisco disqualifies a supplier because of
quality issues with that supplier's product, or for other reasons (i.e. EMI
or power requirements). Disqualified suppliers may continue to sell their
GBIC's and please note that they or parties that have purchased from them
may claim that their GBIC's are Cisco approved. Such statements are at best
unreliable and our customers should understand that only by sourcing GBIC's
directly from Cisco or a Cisco Authorized Channel, can our customers be
confident they are getting Cisco approved modules that will qualify for
Cisco support (Cisco sourced GBICs can be identified by the Cisco logo and
trademarks on the label). We are taking appropriate legal action against
suppliers using such false and misleading statements.


What does Cisco expect from its Authorized Channels?
Obviously we believe strongly that our GBIC's are superior in terms of
quality and performance to any non-Cisco GBIC. Nevertheless, you may in
certain instances prefer to resell third party GBIC's. As stated above, this
may occasionally give rise to support and warranty issues, and may cause
confusion with the end users. In order to prevent such issues and to protect
Cisco's brand and reputation we would like to ask you to observe the
following guidelines when reselling non-Cisco GBIC's together with or
already installed in any Cisco products you are reselling:

Inform the end user of the fact that he is receiving a non-Cisco GBIC;
Inform the end user that such a non-Cisco GBIC will not qualify for
Cisco support;
Inform the end user of the brand of the non-Cisco GBIC and how they can
obtain support on those products and what the warranty terms are.

Although this statement specifically covers GBIC's, the same issues arise
with other third party components e.g. memory or cables.  With regard to
those products the same principles as set out in this letter apply.

For any specific questions please contact your Cisco channel account manager.

Yours Sincerely

was a great experience. The volume of data that you need to absorb is great,
and the way they structure it and keep it fresh was fantastic. To get a
better understanding of all around security and policy the GSEC is great. Im
up for a renew and I definitely am going to do it.

Does anyone out there have any feedback about the GIAC Certification tracks?
I'm thinking of taking their online courses but wanted to see if you guys
heard any thing negative or positive about them.

RE: 2500 won't boot...any ideas? [7:41414]

duh

i don't know why i never learned to use the break key.  if i've ever
lost a password in the past, i've always changed the
config-register...oh well.  the break key worked.  i booted it into rom,
and loaded a new config.  it turns out that my config was created with
an IOS that is incompatible with like every other version...

anyway, thanks everybody, for your help...sorry that it turned out to be
my lame-o moves...

Ed- I'm trying to make sense of the output and your trouble shooting
steps, as explained in your E-mail.  If the 2511 did not have 11.0(10c)
ROMs, then the router would more or less hang-up when upgraded beyond
11.3 or 12.0 (I don't remember the cutoff for the 10.0 ROMs).

If the router seems to be choking with the use of 12.2, issue the Cntrl
BREAK upon bootup and reload an older IOS (say 12.0 or 12.1) to rule out
some sort of bug.  Though I have not had issues with 12.2 in my 2500s,
this code is not a GR (General Release) and most definitely could be
reacting with the FLASH and RAM "manufacturer" combination that have
going on in your 2511.

There is also a slim chance you have zapped the RAM (rare but true).

Anywho- I "believe" what you are showing us here is an issue where the
memory works fine in the 2522.  The "Read Only" seems a little weird
(after the 16 Megs FLASH), but then again...  certain versions of code
read this way and in the upgrade process automatically call for a
software reload that enables the "Read Only" to change upon coming back
up.

If I've missed the boat, please offer more info.  For better or worse, I
have probably upgraded no less than a 100 2500s and 3000s (Y2K) in the
few short years I have been working on Cisco.

All the best !!!
Phil

Subject: 2500 won't boot...any ideas? [7:41414]

my 2511 was working fine a few days ago with--i believe--11.0xx
software.  i created a configuration and saved it.  yesterday, i
upgraded the RAM so that i could load 12.2xx.

the router won't fully boot up, and it never goes into the config or
into rommon.  i don't get it.  again, it was working a few days ago.
unfortunately, i can't put the old chips back in b/c i overwrote them
already--ugh.  i loaded up 12.2.7 onto the flash via another router and
tried to boot it up again in the 2522...

here's the output from when i start up the router, to where it hangs...

Team,

I was wondering
Is it possible to make a router respond to an access-list blocking, 
using a custom-made user defined phrase?

For example, if we deny telnet from a host we need to reply to
him "Access-list blocks incoming telnet..."

?

Not knowing the specific answer, I will say that in terms of good security

as to why something fails.  Detailed responses can provide help to the bad

This is possible if you have an Cisco IDS and CSPM.In that you can point

RE: Connecting printer through Cisco Routers [7:41473]

2002-04-15 Thread Blair, Philip S

My interpretation of the question may be incorrect but it sounds like your
looking to extend a RS-232 connection across your router network? 

PC-> RS-232-> Router-> Net-> Router-> RS-232-> Printer

I assume in theory you could use STUN (serial tunneling), but throw in the
fact that you want to use the console port and things become a little more
difficult.

Terminal server reverse telnet ? [7:41496]

2002-04-15 Thread Mike Sweeney

I would swear I've seen this answered here before but I can seem to find it
now that I need it.

The short version is I have a terminal server connected to a router. The
router is config'ed on the AUX port for a modem. I reverse telnet into the
router(normal) from the terminalserver. Then I need to reverse telnet to the
modem on the router. So far so good. The problem is when I need to pause and
drop out of the AUX session back to the router. The normal shift 6 x kicks
me all the way back to the terminalserver and not just the router that is
being worked on. I know there is a way around this but I dont remember
it::whimper::

If someone would be kind enough to post an answer, link etc.. Meanwhile I'll
keep looking on my own.

THanks!!

MikeS

Swicthing and sniffing [7:41501]

2002-04-15 Thread group study

Hi,

I like to know how you can sniff (I am using Network General)a device if we
are using switches.I can't sniff any data of a particular device which has
got problems.Normally, what I do is unplug the device from the switch and
put the sniffer and the device together in a hub and monitor what is wrong
with the device.This seems to be cumbersome especially if lots of devices
are connnected to the switch and it seems that it is not the correct way
when the device is put on the network (in the actual switch).I know that
certain switches allow the port to be open like 3Com and HP.But what if
certain switches like Netgear doesn't allow that.

I appreciate anybody's help in this matter and normally how you troubleshoot
with switches using a sniffer.

I have a Catalyst 5000 in my lab in which I anticipate the same problem.

Thanks,

Jay

A little help in the right direction [7:41500]

2002-04-15 Thread Joel Panetta

Can anyone point me in the right direction to implement a pros and cons
document for a back bone and infrastructure upgrade? we have a Catalyst 5000
back bone I want to push to 6509 with redundancy but have to put it all on
paper.

 Thanks

RE: 2500 won't boot...any ideas? [7:41414]

2002-04-15 Thread Circusnuts_1999

No ROMMON on this one- in 2500 "boot" mode there's o/r 0x41 (natural
boot process) or 42 (42 being the load without NVRAM configs).  Then
type I or b to reload the router with the new config register settings.

Issue a break and stop the bootup sequence.  Go into rommon mode and
change
the config-reg to 0x142.  Reload and erase your config (WR E) when it
goes
into bootrom mode.  Change your config-reg back to 0x2102 and reboot the
router.  Let me know if that does not work.

Re: Riddle [7:41491]

2002-04-15 Thread Dimitris Vassilopoulos

I agree with you Chuck. It's very unsecure indeed...

However, consider it as one of the certifications' riddle...
Too theoretic, but must be solved... It has a solution, and it
is ROUTER oriented. No IDS or CSPM included...

In case you come up with something let me know...

Thanx

Dvass

Signature for blocking telnet to SMTP server [7:41565]

2002-04-15 Thread Cisco Breaker

Hi,

Is it possible to block telnet to SMTP server from port 25 with IDS. I want
to create a custom signature for this but I don't know how this can be done.
If  I write a signature beginning with hello it will block all mail traffic
because all of them starts with hello as I know.  And are there any
resources that tells how to write a custom signature. We are using CSPM
2.3.3i.

Any help will be appreciated.

Best regards,

Cisco Breaker
