Hi all Thanks for all the replies.
1) My total network consist of some 100 vlans. I don't think that's a lot right? 2) parser cache can be configured on the router, but it doesn't seem to have any effect. It's still about 7-10 minutes long 3) After some investigation I found that show running config interface <interface> is at its usual speed (ie, instantaneous). Not sure why this one works. 4) What do you mean by switching back to non-modular IOS? /Jason -----Original Message----- From: Eric Pedersen [mailto:[EMAIL PROTECTED] Sent: Tuesday, September 30, 2008 11:42 PM To: [email protected]; Jason Koh Subject: Re: [c-nsp] Extremely slow performing show running-config We had a problem with really slow config access with modular IOS on sup720s. It took several minutes to do show running-config or write mem. I don't remember the version, but switching back to non-modular IOS fixed it. Hi there I have a strange problem with a pair of cat6509s. Both are connected to each other via OSPF and IBGP, with EBGP with my upstream providers. Whenever I use show running-config, it will pause for an extremely long time after the line "Building Configuration". It happens from either console or telnet sessions. At first I thought it was a CPU or memory problem, but "show proc cpu" and "show proc mem" shows nothing out of the ordinary (cpu less than 20% and memory with more than 256M free). Rebooting both machines doesn't solve the problem either. After further investigations, I found out that the same problem occurs when I do the following as well. 1) copy running-config startup-config 2) write memory Show startup-config does not have this problem. >From what I see, it looks like a problem with NVRAM. Also predictably, >the session doing any of the 3 commands will lock the NVRAM preventing other sessions from doing a show startup-config as well. Killing the session (clear line vty or clear line console) that are doing any of the 3 command doesn't seem to kill the session at all. It doesn't seem to be a hardware issue as both cat6509s display the same problem since early this month at the same time. Any insights on this will be greatly appreciated. Thanks. /Jason _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
