Creating a Port-Based VLAN

To configure a port-based VLAN, create the VLAN and then add physical interfaces or port channel (LAG) interfaces to the VLAN.

NOTE The Default VLAN (VLAN 1) is part of the system startup configuration and does not require configuration.

A VLAN is active only if the VLAN contains interfaces and those interfaces are operationally up. As shown in the following example, VLAN 1 is inactive because it does not contain any interfaces. The other VLANs contain enabled interfaces and are active.

NOTE In a VLAN, the shutdown command stops Layer 3 (routed) traffic only. Layer 2 traffic continues to pass through the VLAN. If the VLAN is not a routed VLAN (that is, configured with an IP address), the shutdown command has no affect on VLAN traffic.

When you delete a VLAN (using the no interface vlan vlan-id command), any interfaces assigned to that VLAN are assigned to the Default VLAN as untagged interfaces.

To create a port-based VLAN, use the following command.

Configure a port-based VLAN (if the VLAN-ID is different from the Default VLAN ID) and enter INTERFACE VLAN mode.
CONFIGURATION mode
interface vlan vlan-id
To activate the VLAN, after you create a VLAN, assign interfaces in Layer 2 mode to the VLAN.

Example of Verifying a Port-Based VLAN

To view the configured VLANs, use the show vlan command in EXEC Privilege mode.
