Hi all,
assumed I have configured a Gigabit Interface with the max. possible MTU of 9216 byte (incl. L2 Header and Trailer)
interface g1/1
mtu 9198
or
system mtu jumbo 9198
Cisco wrote the following:
"... When you enable a port for 802.1q trunking, the switch automatically assumes that an extra four bytes of data are appended on, and increment the frame size of the L2 packet. ..."

If I configure the above-named interface as a dot1q trunk, does this raise the MTU for additional 4 bytes to 9220 byte???
Thanks!
Hakan
