[j-nsp] ex4200 throughput trouble on 10GE interface

[masood at nexlinx.net.pk]

this can be an indication of faulty hardware or dot1q trunking
configuration issues. on cisco boxes oversize counter, count number of
packets received by the port from the network, where the packets were more
than 1514 bytes. for 802.1Q trunk links you will notice this. is this a
trunk link?

Masood
