The maximum MTU for an ethernet frame is 1500. http://www.ussg.iu.edu/hypermail/lin...11.0/0286.html

hi
ok. but i implement VLAN on cisco switch and need to enable 802.1q trunking on the server NIC.
8021q trunking adds 4byets for taging, so if the frame is 1500 byet + 4byet for vlan which is 1504 and the frane will corupted.

how can i solve the peoblem?
