I have a Cat3550 which is suffering output buffer failures. In 1 week, it has sufferred 1.5 million failures. Reading the output interperter, it suggests a software upgrade, which I did (from 12.2(25)SEE2 to 12.2(46)SE)but has not changed anything.
Attached is the sho buffers for this switch.
The users attached to this switch are suffering disconnections from windows terminal servers.
