I have a firewall with a vge0 interface doing firewalling/routing between Gigabit VLANs. I am trying to configure the mtu of the interface to support larger frames.
The NIC is a VIA VT6122
According to the vge man page:
"ifconfig: SIOCSIFMTU: Invalid argument"
What are the valid sizes for the MTU value? I want to set it to a max of 9K as that is the largest frame size my switch will support.
Also does one change the MTU on the real interface or the VLAN interface?
It was a new day yesterday, but it's an old day now.
