Traffic Monitoring [7:64351]
Greetings, I have a 3640 connecting to the Internet on T-1 via PIX-515 in the central office. Multiple branch offices have frame relay connections to the central office. One branch office is complaining about slow connectivity. Checking 'show frame pvc' for that office indicates that they are downloading 100x more than any other branch office. Each branch office has its own subnet. Can you recommend software to determine which hosts at the branch office generate all this traffic and what kind of traffic (ie. protocol) it is? I am more comfortable with unix tools, and I am the central office. The branch offices only have windows machines. Will summarize. PS. please contact me at [EMAIL PROTECTED], I subscribe to the digest, and want to get on this ASAP. Igor Vilensky REM Inc.

How Can I tell that someone else is in global config mode? [7:64079]
Greetings, I wrote a very simple script which logs to a router, executes a configuration command ( usually 'username xxx password xxx'), and exits. It has been pointed out that if somebody else is in global command mode it might be trouble. I know that problems occur when two people try to edit a unix text file at the same time. Is there any mechanism IOS utilizes to safeguard against conflicts of this nature? In case it is problematic, I would like to know how to determine if anybody else is in global config mode. Given that, my script could wait until nobody else is in that mode and then execute the command. Thanks for your consideration. Will summarize. Igor Vilensky REM Inc.

Doyle Chapter 7 Troubleshooting Question 1?
The network is diagrammed in Fig.7-30 Respective routing tables are in Figs. 7-(31-33) The question regards which subnets are unreachable. All ethernet links are subnets of 172.168.13.0. ether interface address for Router A is: 172.168.13.86/29, subnet address x.x.x.80/29 for B: 172.168.13.90/28, subnet address x.x.x.80/28 for C: 172.168.13.75/27, subnet address x.x.x.64/27 how does this affect routing? the answer key only addresses issues of rip version 1 and 2 compatibility. RTC subnet includes hosts 65-94, covering A and B RTB subnet includes hosts 81-94, covering A RTA subnet includes hosts 81-86 the config includes 'no ip classless' on all routers does that play a role? what role does longest-prefix rule play, and, lastly, what about the fact that these subnets are directly connected to their respective routers? thanks, igor = __ Do You Yahoo!?

exam topics for various cisco tests
i just got my CCNA i noticed that the online networking academy curriculum had detailed list of 60 topics to review for CCNA test (not that i did), which did not appear on the exam info at the www.cisco.com cisco website's exam info contains a detailed list for routing 2, and CCDA/DP tests. however, the list of topics for the other 3 CCNP tests is very sparse additionally, there are some goals for CCIE written test, but no detailed topics or objectives. i think it would be useful to obtain this, maybe contact cisco, or if such thing is not available come up with our own list. let me know if you have any ideas/interest in this. igor vilenskyDo You Yahoo!?

Re: RouterSim
I have used Sybex CCNA prep version of RouterSim, it is innacurate, you can go through all listed labs in less than 10 hours, and it costs 100 bucks, although you can get a deal online. I thought it was rather disappointing. there is some functionality, so you can setup your own lab exercizes, has anyone tried that? igor --- Marshal Schoener <[EMAIL PROTECTED]> wrote: > Does anyone have any experience with the RouterSim > product? > > It seems like it does a lot of commands, and gives > you a few routers, > switches, and even nodes on each end... > It even gives you a BRI to practice setting up > ISDN!!! > It's about $200... > > Any opinions? > > > **NOTE: New CCNA/CCDA List has been formed.

Re: Class 2 Fast Ethernet repeater
so, would 1 bit time for fast ethernet be 1/100,000,000 seconds and 92 bit times 92/100,000,000 seconds? igor Ejay Hire <[EMAIL PROTECTED]> wrote: A bit time is the minimum width of a 1 pulse on a network medium.i.e. The first part of an ethernet preamble is a 64 bit on/off/on/off pattern to synchronizes recievers at the physical layer. This 64 bit preamble is exactly 64 bit-times. Bit times vary by Physical/MAC layer protocols. i.e. 16mbps Token ring's bit time is 4 times shorter than 4mbps token ring because it transmits 4 times as much data in the same timeslot.Original Message FollowsFrom: John lay <[EMAIL PROTECTED]>Reply-To: John lay <[EMAIL PROTECTED]>To: [EMAIL PROTECTED]Subject: Class 2 Fast Ethernet repeaterDate: Thu, 7 Sep 2000 01:47:21 -0700 (PDT)Guys,On the CCDA book it is mentioned that "Class 2 Fast Ethernet repeaters havea maximum delay of 92 bit times"Is this means that the maximum allowed delay is 92 bit per second ?What is! bit times ?Thanks a lot___Say Bye to Slow Internet!http://www.home.com/xinbox/signup.html___UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.htmlFAQ, list archives, and subscription info: http://www.groupstudy.comReport misconduct and Nondisclosure violations to [EMAIL PROTECTED]_Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.Share information about yourself, create your own public profile at http://profiles.msn.com.___UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.htmlFAQ, list archives, and subscription info: http://www.groupstudy.comReport misconduct and Nondisclosure violations to [EMAIL PROTECTED]Do You Yahoo!?
