I recently added a vlan to a Cisco 3524xl (SW1) which is connected to a 3508. I configured trunking on SW1 on G0/1 and added the "switchport access vlan 22" statement to the rest of the ports except port 1 which is configured for the other Vlan.
0/2 -> 0/24 + G0/2 = switchport access vlan 22
0/1 = vlan 9
G0/1 = Trunking -> connected to the 3508
I also have another 3524xl (SW2) which is connected from G0/2 to G0/2 of SW1
I thought that I could connect the two switches without a problem using G0/2 of SW1 as an access port.
Everything seems to be working except I am receiving this error on the syslog server I have setup.
CDP-4-NATIVE_VLAN_MISMATCH: Native VLAN mismatch discovered on GigabitEthernet0/2 (22), with MCCF_1st_FL_Admin_1 GigabitEthernet0/2 (1).
SW2 is setup with native vlan 1, the default because I am not trunking that switch at all.
I can see where the error is coming from but what is the best way to resolve this?
Should I just disable CDP or will this mismatch cause issues down the road?
