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

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.
