Selective outages?
We have a small network. A 2620 on either side of a T1. Computers A, B, and C are on one side. Computers D, E, and F are on the other side. Sometimes, E will decide it won't communicate with C. E can't ping C. C can't ping E. E can ping A and B. C can ping D and F. A and B can ping D, E, and F. After a few minutes, E will be able to ping C. A while later, B will decide it can't communicate with F, and so on. It seems to happen when the T1 hiccups (the large, well-known multinational company we got it from can't seem to make it work consistently). I think it may happen if the two machines are communicating when the T1 hiccups. I'm not really sure on this - it is a casual observance. Sometimes the pings will get "request timed out", and other times "destination host unreachable". What is causing this, and how can I prevent it? I don't recall seeing this in any other networks I have worked on. Thanks, Benjamin Walling BTW, our T1 provider is blaming the Super Bowl (we're in Tampa) for all of our troubles. They say their cross connects keep getting stolen by people hooking up lines for the Super Bowl. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Hyperterminal problem
Not really a Cisco question (directly), but everyone here should have ample experience using COM ports to get consoles Hyperterminal is saying 'Unable to open COM1'.

Using modular CSU/DSU on 2600
I've entered all the commands to set up the T1 service module, but when I do a show run or show start, I don't see them (except for one line). A show interface shows some of the settings (ESF, B8ZS), but I'm just curious how it keeps the settings. Are there any useful commands for troubleshooting the T1 line through the service module? The manuals aren't that great, and I'm not used to having the internal CSU.

Behavior of Cisco PAT/NAT?
If I set up a NAT pool of only 1 address, the router/pix uses PAT. Under PAT, I can have 65K hosts (or connections from hosts) connecting to the internet. If I set up a NAT pool of more than 1 address, the router/pix uses NAT. Under NAT, I can have 1 host per address in the NAT pool. Does this sound right? I have two available address to get my users out with. If I put them both in a pool, will I only get two out at a time, or will it allow 65K connections per address in the pool?

If you do a ping, it is not a test of whether WINS is working because there are other ways to resolve a name that Windows will use. You can 'ping hostname' and get a response when you do not have WINS working. You can also 'ping hostname' when you do not have DNS working. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: Still doesn't work: tough VPN question
Absolutely. It just makes a difference what order Windows uses to resolve. Ping, telnet, etc will try to resolve a DNS as a DNS name. If it fails at this, it will use WINS/LMHosts. So, yes you can 'telnet netbiosname' If you just type in 'ping bob', Windows will tack on 'yourdomain.com' and try to resolve it using DNS. So, you are likely just resolving this with DNS. However, if your DNS host name and your NetBIOS name are different, then you will use WINS to resolve this. So, using ping will not verfiy that WINS is working, unless you use a NetBIOS name that is not also a DNS name. If the NetBIOS name and the DNS host name are the same, your computer could resolve that name with DNS. So, you will not verify that WINS is working by pinging something where the NetBIOS name is the same as the DNS host name.

Re: Still doesn't work: tough VPN question
Yes, WINS resolves NetBIOS names to IP addresses, but only for Windows networking functions. It is not used for ping, ftp, telnet, etc. It is used for name resolution with relation to file sharing, domain traffic, etc. The order in which a Windows box will try to resolve a DNS name (what happens when you ping): Host file DNS Cache WINS Broadcast LMHosts The order in which a Windows box will try to resolve a NetBIOS name: Cache WINS Broadcast LMHosts Hosts DNS (of course you can modify the NetBIOS node type and change this) ""Frank Wells"" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED]... > Name resolution is exactly what WINS does!

Re: Still doesn't work: tough VPN question
Pinging does not verify name resolution for WINS. Ping will resolve a name using DNS. MS uses WINS (NetBIOS naming) for Domain Logins and for mapping drives, etc. Try this link on Cisco's website for help with coordinating your NT domain with your network layout: http://www.cisco.com/warp/public/473/winnt_dg.htm It covers WINS and things like that.

Re: bandwidth estimation!
This seemed to not make it to the list, so I'll try again. -- Forwarded by Benjamin Walling/HQ/INDECON on 06/14/2000 08:11 AM --- Benjamin Walling 06/13/2000 09:01 PM To: [EMAIL PROTECTED] cc: Subject: Re: bandwidth estimation! (Document link not converted) Well, assuming 56k dialup (you said free ISP, I'm guessing it's not free DSL), I would figure it like this: Assume a 6:1 ratio on bandwidth (I know several ISPs that feel this is the safe ratio to go by). 1000 users times 56k= 56Mbit. Divide that by 6 and you get about 9Mbit (6 T1s). However, you don't expect to have all 1000 users online at the same time, do you (I didn't gather whether you would have 1000 customers or 1000 modems)? So, you don't need all of this bandwidth. Figure that maybe 25% of your users are online at any time (you would need a 250 modem setup for this), and your bandwidth is 14Mbit, divided by 6 and you get 2.3Mbit. A couple of T1s should cover you in this case. The 6:1 comes from the fact that web surfing is very bursty by nature (client sends request, server send pages, client reads for a while, repeat). Email is probably factored in there, but I'm pretty sure the ratio is 6:1 inclusive of email. Hope that helps you some.

Re: OSPF configuration - Please help
Are you able to ping the other router? Do you see it with 'sh cdp nei'? Also,
you should do 'shut' then 'no shut'. The other way around shuts down the
interfaces (the way you said below). Also, on Router B, I see no indication of
an area statement. IE: network 192.1.1.0 0.0.0.255 area 0. There is a network
statement under router ospf, but I am not familiar enough to know the effects of
putting 0.0.0.0 0.0.0.0 in that statement. My understanding is that you must
give it an area (although if you don't, it may default to area 0).

Subject: OSPF configuration - Please help
Hello:
I have two 2503 and I am following Hutnik's to configure OSPF.
I connected RouterA, s0 (DCE) to RouterB, s0(DTE).
When I enter #show ip ospf int I see the following:
...
Transmit Delay is 1 sec, State DOWN
Hello due in...
...
The State should be "POINT_TO_POINT".
The routers don't see each other. (#show ip route doesn't display OSPF
entry).
I entered "no shut" and "shut" in both routers s0 interfaces but it didn't
work. Any idea of what is wrong ?

Re: value of cisco cert
This would be entirely feasible, as Novell does something like that. I would like to see problems that requires multiple commands and starts the test taker in exec mode. That way, they show they can get around, and show they understand. The one line answers do not lend themselves to prove anything except syntax has been learned. Routersim seems to work well, and probably could be licensed and modified to serve as in a test environment. This would add some lab-like feel to the tests and not cause Cisco considerable cost to administer. Novell currently has simulations in their exams. They will open up administration utilities and ask you to perform a task, generally about 4 steps. However, they let you click around for as long as it took you to figure out what to do (there is a time limit on the exam itself, so you could hurt yourself doing this).

I think that the test can include an objective that focuses on real world scenarios. For example, the CIT exam, can have a troubleshooting problem that you have to really have to troubleshoot, and the procedure can be evaluated; the same way a the procedure is evaluated on some engineering exams. Something as simple as that can really enhance the value of Cisco certifications. I would like to see the value of Cisco certifications increase. T.

Re: CCNA 1.0 vs. 2.0
I sat the new course, ICND, and took the old test. There were things like VLANs and switching in the course that were not on the 1.0 test or in the 1.0 prep material. I think that Cisco has the requirements for each up on the web site.

I would use show hardware. Show version just shows the name of the image. I could name it anything I want and load it into flash.
