I keep getting these 2 syslog errors:
4767: 004805: * Native VLAN mismatch discovered on FastEthernet0/2 (2), with switchcore5 FastEthernet0/21 (1).
And then the opposite direction
4768: 004806: * Native VLAN mismatch discovered on FastEthernet0/21 (1), with switchcore5 FastEthernet0/2 (2).
It's a Cisco Cataylst 2950 and I have updated the IOS to the lastest, everything seems to be working ok.
The 2 ports are below:
description Link - Core Switch to LAN
switchport access vlan 2
switchport mode access
description VLAN 1 for LAN IP
