Cisco 7507 PA-4E full duplex operation [7:34076]
Cisco states that their PA-4E module (four port 10BaseT) for 7500 Series routers is capable of being configured for full duplex operation. Under the ethernet interface, no "full-duplex" option available. Also, the command "no half-duplex" returns "Invalid input". Has anyone configured this module for 10M/full duplex operation? Thanks.

Re: Cisco 7507 PA-4E full duplex operation [7:34076]
To answer my own question, Cisco added this feature for 7500 Series routers in IOS releases 12.1.9.6E and later. With this release, the interface command to accomplish this task is "duplex full".

Re: Where to begin? ( troubleshooting frame relay ) [7:34264]
Hello, Have you tried looking for the problem somewhere else. If you have switches in your environment to which these devices are connected. Check for any errors on the ports to which these devices are connected. Look for the symptoms which would induce latency+errors in LAN enironment, like duplex mismatch, etc. Tauseef ""beth"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Hello All, > I have a user with a full T1 frame relay circuit and a user with a 384k frac > T1 circuit.

Re: Cat5k Reboots sporadically [7:35477]
Sean, If you have redundant power supply in the chassis of the same 5500, you should not be seeing switch resets due to one power supply failure. All you should see is that the logs will indicate that power supply 1 is reseting. Having said that, if you still suspect that the switch reset is due to pwer supply #1 failures, please read the release notes of the CatOS you are running and see if there are any caveats listed regarding this scenario. It would also help to place a call to Cisco TAC as they have more visibility to bug lists than published for general public. Please make sure that you have the serial number of the switch and "show tech-support" (OS dependent) output handy when you place a call to Cisco. HTH.

Re: Latency in Telnet, intervlan routing [7:38187]
Here are few things you could look into, 1) Is this a new config.? 2) Did it ever work before? if yes, what changed? 3) Assuming that routing is setup correctly on the Cat5K routing module (if this is being used), (a) do you have the right static routing setup on the server to respond to traffic coming from different network? (b) where is your default gateway point to (as next hop) on your server? (c) If the server is a unix box, do you have any tcp wrappers? any ip-chains? any firewall? 4) If everything checks out OK thus far, check for issues with switch and routing module configuration 5) What are you using to route inter-vlan traffic? is it routing module in Cat5K or is it external router? 6) If it is internal routing module, have you configured the vlan interfaces correctly? 7) Once all the end stations are connected, are the vlan interfaces show as "up" and "up"? 8) How about the ip addressing? are all the configurations falling withing their respective masking bounderies? 9) How about the ACLs? 10) So on and so forth... I hope that somewhere along this path, you'll find the issue. Please do share with us what was the resolution.

Re: Latency in Telnet, intervlan routing [7:38187]
In the Unix servers, please check for /etc/resolve.conf and see if name servers are configured correctly. If these Unix servers don't require name services, please add just their ip addresses to /etc/hosts file and then check for response time. This is "reverse nam lookup" issue. Thanks.
