Native trunk vlan mismatch

[jadkins01]

I'm having issues with a 2960 saying native trunk mismatch. The 2960 is trunked to a 3750. I check the configs on both ports and both are set to the same native vlan. Only the 2960 is complaining of this issue and not the 3750. The 2960 is passing internet traffic, but I am unable to ping the IP of the 2960 or telnet. From the 2960 console, I am unable to ping our gateway. Already tried rebooting. I'm at a lose. HELP!

Try deleting the native vlan and adding it again.

Can you post the interface config from both switches?

Presumably Vlan 3 exists in the Vlan database on both sides?

Have you tried defaulting the config on both sides and typing it in again?

Can you post the exact error from the switch log?
