This should also work. Its supported on the 2950 for sure. Not sure about the older 2924. This is a function of DTP running on the port.

switchport nonegotiate

Subject: [c-nsp] Native VLAN mismatches between 2924/2950

I'm getting a lot of Native VLAN mismatches between my 2950 and 2924s.
This is due to the case difference on the 2 platforms, between VLAN1 and
Vlan1.

Is there any way to (1) fix the error or (2) suppress the CDP error messages

Nov 30 14:54:27 192.168.0.113 26469: %CDP-4-NATIVE_VLAN_MISMATCH: Native
VLAN mismatch discovered on FastEthernet0/15 (0), with SW1
FastEthernet0/18 (1).

The documentation and a google search indicate that simply changing the
name doesn't work; changing the conf file, uploading via tftp didn't
work either. And you can't simply delete/recreate the Vlan1.

Regards,

Pierre Lamy
