The network consists of several Catalysts 3548, they are all connected to 3508 with Gigabit. All have the same IOS version 12.0(5.2)XU.
One of the 3548 has a 3524 connected with Gigastack, the Gigastack is configured as half duplex cascade. This 3548 counts a lot of underruns and output buffer failures, but seems to operate normally.
I found a bug CSCdv11799 which seems to fit to this problem, but the description does not help really. Does anyone know more about it? Why does only one the the 3548 in that network show these symptoms? What frames increase this counters?
