8.2 VLAN Configuration  
  8.2.4 Verifying VLAN configuration  
A good practice is to verify VLAN configuration by using the show vlan, show vlan brief, or show vlan id id_number commands.

The following facts apply to VLANs:

  • A created VLAN remains unused until it is mapped to switch ports.
  • All Ethernet ports are on VLAN 1 by default.

Refer to Figure for a list of applicable commands.

Figure shows the steps necessary to assign a new VLAN to a port on the Sydney switch.

Figures and list the output of the show vlan and show vlan brief commands.
