I was wondering how to setup jumbo frames on a specific vlan other than vlan 1. i.e. vlan 4000. Is it as simple as setting system mtu routing to 9000 or whatever size I wanted, and is it possible to narrow it down to just one vlan? Actually I see under the vlan interface this:
mtu VLAN Maximum Transmission Unit
Do I need to set that in addition to the system mtu setting or perhaps only the mtu setting under the vlan? So, i.e.
int vlan 4000
