Let’s say you wind up in a testing environment and you want to figure out what vlan they are using as the native vlan, but you’re configuring fresh trunk ports so it may not be abundantly obvious. Allowed vlans can be specified on any trunk port with the switchport trunk allowed vlan command. cisco recommends not using vlan 1, restricting vlan 1 from trunk links (switchport trunk allowed command), and. therefore, different vlan numbers can be configured on both sides of a single trunk link leading to native vlan mismatch.
