I have 2 Cisco switches connected with Ethernet cable. I am getting a CDP-native-VLAN-mismatch error on 1 switch.
Let me say this setup for easy understanding....SW-1-F0/1-Vlan1-------------SW-2-F0/2-Vlan2
Vlan-1 IP is 10.1.1.1
Vlan-2 IP is 126.96.36.199
I dont have access to SW2 switch. I want to ping SW2 - 188.8.131.52 from SW-1. I did the following, nothing worked...
1) I changed the vlan of the SW1, port F0/1 to Vlan2. Also assigned 184.108.40.206 IP in Vlan-1 as secondary IP. But still I cant ping
2) Made SW1, port0/1 as trunk port. Vlan1 still has 220.127.116.11 as secondary IP, but not able tp ping.
3) Made SW1, port F0/1 as L3 interface and assigned 18.104.22.168...Removed secondary IP in Vlan 1. Still not able to ping
But show cdp neigh is showing the other switch..What are the reasons SW-1 is not able to ping SW-2?
