Hello there,
I am trying to change MTU of a bge interface :
# ifconfig bge1 mtu 1504
ifconfig: SIOCSIFMTU: Invalid argument
(MTU is 1504 because some 3550 EMI are in the near of this marchine
and needs same MTU everywhere to exchange OSPF packets).
Is this normal of does bge interface doesn't support mtu > 1500 ?
