Re: Catalyst 4507R Active SupIV Hangs when Hardware Reseted

kaustav.g · ‎02-20-2003

Dear All,

I noticed a peculiar event happening to a 4507R with Active SUP IV in slot 1 and Standby SUP in slot 2. The active and standby where in RPR mode.

I used logging console and checked that all change where synched with the standby sup. Then I hardware resetted to checvk the failover using the reset switch.The following occured

The standby sup became active but the original active sup hanged and was not responding . The show module command showed only mac address of the sup in slot 2 and other modules.The slot 1showed no mac address of the sup 1.

Even rebooting the switch worsened the problem as the sup in slot 2 also went in hang state.

Kindly help

Regards

Kaustav

Can you console into the Sups? Let us know what prompt the console displays?
