This is happening because the port on one switch is a member of VLAN 9 and the corresponding port on the other switch is a member of VLAN 7.

The ports should be members of the same VLAN. If you really need them to be in different VLANs, you can either (A) disable CDP on the ports, (B) disable logging or (C) ignore the messages.
