Configuring a super VLAN
When you configure a super VLAN, follow these restrictions and guidelines:
Do not configure a VLAN as both a super VLAN and a guest VLAN, Auth-Fail VLAN, or critical VLAN for a port, and vice versa. For more information about guest VLANs, Auth-Fail VLANs, and critical VLANs, see Security Configuration Guide.
Do not configure a VLAN as both a super VLAN and a MAC-based VLAN.
Do not configure a VLAN as both a super VLAN and a sub-VLAN.
You can configure Layer 2 multicast for super VLANs. However, the configuration does not take effect because super VLANs do not have physical ports.
To configure a super VLAN:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter VLAN view. | vlan vlan-id | N/A |
3. Configure the VLAN as a super VLAN. | supervlan | By default, a VLAN is not a super VLAN. |
4. Associate the super VLAN with the sub-VLANs. | subvlan vlan-id-list | By default, a super VLAN is not associated with any sub-VLANs. Make sure the sub-VLANs already exist before associating them with a super VLAN. |
