Hello,

Can you show the whole inferface readout -also

sh int xx stats
sh int xx switching ( hidden command)

sh ip int xx

after that can you clear the counters on this interface-

clear counters xxx

Gig port physically running at gig?

Your default egress queue, if 40, might be too small (leading to premature bust drop). Try increasing egress queue's size, you might try 512.
