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.
