Brand New ME3400G Can't Ping!

Posted on in Networking

Old Cisco Systems LogoAfter cracking open a brand new Catalyst ME3400G, we weren't able to get it upgraded to the latest version of software. In fact, we couldn't even ping anything on the local subnet.

interface GigabitEthernet0/1
 port-type nni

Problem solved!
