I need ot be educated. Why would someone place a trunk port in a vlan. I always thought of a port as either being one that supports a trunk or one that supports an end-user (access port).
Check out this config:
description Connection to TLS
switchport access vlan 21
switchport trunk encapsulation dot1q
switchport trunk native vlan 21
switchport mode trunk
This trunk port is not pruning any vlans, right?
Given this config, by default, it should be allowing traffic from all vlans, right?
What is the significance of placing it in vlan 21 and configuring the native vlan as vlan 21 also?
