Hi,
from 4 ge interfaces on one ge PIC all 4 interfaces show the errors ,while
only 2 of them are configured as trunks the other 2 have only one vlan
configured each.All the 4 interfaces have the L2 errors.Last night we tried
to swap the PIC but today the same errors.
We also see packet drops under the class-of-service
