Show Cisco Switch Trunk Ports

A trunk-port is a port configured to pass frames including broadcast frames through multiple VLAN switches. Its main purpose is to carry multi-vlan traffic through single port using unique identifying tags. You could use universal 802.1Q protocol or Cisco proprietary Inter-Switch Link (ISL) protocol.

To view Trunk Ports on Cisco switch, use show interface trunk command

SW03#show interface trunk
Port Mode Encapsulation Status Native vlan
Fa0/1 on 802.1q trunking 1
Fa0/3 on 802.1q trunking 1
Fa0/4 on 802.1q trunking 1
