Re: about 2950 error message

Hi,

this message means that CDP has discovered a mismatch of native VLAN configuration.

So:

- if the int fa0/24 is an access port, there is an interface on the other line side which has been assigned to a different VLAN,

- if the int fa0/24 is a 802.1q trunk, there are different native VLANs configured on the trunk sides.

Regards,

Milan
