Protocol Down in serial interface

[abekeris]

How can, in a serial interface (frame relay), the protocol go to the down state ?

We have two routers and it happened with the same serial interface in each router at the same time.

The routers are cisco 7304 with ios 12.2.20S

We fixed the problem with a reboot of both routers.

Hi,

i found this:

CSCed70198

Release Notes

Symptom: The line protocol may go down.

Conditions: This symptom is observed when Frame Relay fragmentation is enabled

on the main interface.

Workaround: There is no workaround.

Fixed in: 12.2(24.2)S

But for further assistence we need the configuration and the exact hardware.

Regards

Peter
