I have a NetVanta 4430 and I need to enable the Eth 0/1 port and it is stubbornly refusing to come up. I'm having the same problem on three different routers so it must be some config issue.
Here is the config for the port on one of the routers:
interface eth 0/1
description Test Network
ip address 172.16.x.y 255.255.255.0
ip mtu 1500
no rtp quality-monitoring
What am I missing?
