Hello Santhosh,

Here is what needs to be done:

interface gigabitet 2/0/23

switchport trunk native vlan 2

interface gigabitet 2/0/24

switchport trunk vlan 2

Now if you are receiving the log on more trunk links just do the same thing

Regards,

Julio

Hi,

Make sure you have the same exact native vlan on both sides of the connection

for example:

if sw-1 connects to sw-2 and you assign vlan 100 as native vlan this vlan has to be the same on both switches.
