Native VLAN mismatch

Hi,

I am getting this following syslog message on SW1

%CDP-4-NATIVE_VLAN_MISMATCH: Native VLAN mismatch discovered on FastEthernet0/9 (0), with SW1 FastEthernet0/9 (1).

I don't unserstand this message. Isn't VLAN mismatch supposed to be between two switches? Please let me know how to read  the above message and how to fix it

Thanks a lot!

A "Native" VLAN mismatch can occur between devices that have an 802.1q trunk between them.

On your switch where you posted your question issue:

#interface fa0/9
#switch-port trunk native vlan 1

The natives vlans at the ends must match.
