Hi all. I have a real world problem and would like some thoughts, here it goes.
Client has a central site with 7 remote locations. Central site has a 6513 with MSFC2, all sites have T1 in. Eigrp is used between sites and is fine. At the central site lies an AS/400 that all remote sites connect into (users use IBM client access). All is IP no SNA anywhere. What happens is at one and only one location users get bounced out of there session about 4 or 5 times a day. They have full connectivity to the central site, just no AS/400. So I was at the remote site where the problem exists, could ping the as400 fine. So I waited for a "blackout", it came. When the users were bounced I tried to ping the as400 and was unsuccessful. I tried to ping the central router and was good, I tried to ping the vlan ip address that the as400 was in, that was good. I even tried to ping other computers in the same subnet as the as400 and that was good. Tried to ping the as400 again and that was NO good. These outages only last a couple of minutes and then it comes back up. There is NO route flapping. All eigrp neighbors stay put and all routes stay put. What is really strange is that this happens only from one remote location, all other locations are fine. The as400 has only one NIC (ehternet) and all other sites connect to the same IP address. So where is the problem? I checked the port the as400 was plugged into and found some errors, I found out that the port was set to 100/full and the as400 nic was set to 100/half, so I adjusted the port on the switch to 100/half. But if this was the problem, wouldn't all sites have trouble? Could the switch possibly be aging out its cam table to the remote site that is having problems? I don't remember if they blacked out again after changing the duplex (I had been staring at debugs for about 8 hours). I called TAC and bumped up the outbound queue size to the site that is having problems, but haven't had a chance to call them back. Any suggestions? Thanks. -Joe [EMAIL PROTECTED] Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=42391&t=42391 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
