Slow response when in the enable mode on a Catalyst 5509

I have about 70 users that are attached to a Catalyst 5509 which is connected via a gig uplink to a Catalyst 5500 which is connected via ATM backbone to the Main Core Catalyst 6509. We are running IPX/IP thru out our entire network. Users are experiencing extreme slowness logging onto the Network. When I telneted to the switch I notice slowness when I typed a command. When I continuous ping the switch and any device on the switch at the same time I notice that I will loose one ping response after every 13 to 30 reply's on both the switch and the device. I have connected Cisco TAC but no response yet. Any suggestions

thanks

Re: Slow response when in the enable mode on a Catalyst 5509

DUring your slow down periods it might be useful to get processor utilization on your Catalyst "ps -c" just to see if a specific process is eating up your CPU (you might do this on your 5509 and 5500). Have you any port errors to speak of?

You say you uplink VIA ATM. Is this a LANE module? If so how many LEC are on your ELAN? Are you seeing any issues on your LANE module (errors/etc)?

Hope this helps you,

Don
