Workaround CSCea46385 Bug

I need some details about workaround for CSCea46385 Bug.

It is mentioned to disable keepalive on Fiber interfaces and uplink interfaces as 12.2SE releases.

I use GigaStack between 2950 switches. what is recommanded for?

Is it possible to remove keepalive on all trunk interfaces (Copper, Fiber, Gigastack) between switches?

Thanks in advaance


Re: Workaround CSCea46385 Bug

You can disable keepalive on the interfaces. But it is not advisable to disable keepalives. IOS upgrade is teh recommended one. Which port is err-disable on your switch?

Re: Workaround CSCea46385 Bug

err-disable ports was Fiber port.

We have a major issue on our LAN with 25 switchs. After a Gbic change on our 6513, all giga trunk ports connected on this 6513 were err-disable at the same time du to keepalive issue. One hour after the second giga port on all affected 2950 were err-disable. It was very strange because the second giga port was plugged on my secundary 6513. I never exactly understand what's happened.

I take a glance at Bug Tool Web site and there are 2 bugs referenced which could be the origin of my problem: CSCea46385 & CSCeg58877

Tht's why I would like to disable keepalive on all trunk ports, Fiber, Copper and GigaStack.

I try to have a full explanation about keepalive on cisco website but it's really confused. If you can explain me exactly how it's working.
