HIgh X-mit errors

[viled]

I am running 2980's and 2948's in hp blade cabinets. When snooping around I found that the ports have x-mit errors in the 200,000,000 range or higher. They are running 8.4(4) What could be causing this? Also 1 carrier sense error

check for any speed/duplex mismatch at both ends. try to set speed/duplex to auto/auto at both ends and then check if errors are still increasing or not.

Thank you!

I thought I would have seen FCS and alignment errors if that were the case

Xmit-Err Description:

This is an indication that the

internal send (Tx) buffer is full.

Common Causes: A common

cause of Xmit-Err might be

traffic from a high bandwidth

link being switched to a lower

bandwidth link, or traffic from

multiple inbound links being

switched to a single outbound

link. For example, if a large

amount of bursty traffic comes

in on a gigabit interface and is

switched out to a 100Mbps

interface, this might cause

Xmit-Err to increment on the

100Mbps interface. This is

because the interfaces output

buffer is overwhelmed by the

excess traffic due to the speed

mismatch between the incoming

and outgoing bandwidth.
