Creating a Super-VLAN
Context
A super-VLAN consists of several sub-VLANs. A VLANIF interface can be configured for the super-VLAN and assigned an IP address (no physical interface can be added to a super-VLAN).
Procedure
- Run system-view
The system view is displayed.
- Run vlan vlan-id
A VLAN is created, and the VLAN view is displayed.
The VLAN ID of a super-VLAN must be different from every sub-VLAN ID.
- Run aggregate-vlan
A super-VLAN is created.
A super-VLAN cannot contain any physical interfaces.
VLAN 1 cannot be configured as a super-VLAN.
- Run access-vlan { vlan-id1 [ to vlan-id2 ] } &<1-10>
A sub-VLAN is added to a super-VLAN.
Before adding sub-VLANs to a super-VLAN, ensure that these sub-VLANs are not configured with VLANIF interfaces.
The device supports 256 sub-VLANs in a super-VLAN. If too many sub-VLANs are added to the super-VLAN, the ARP broadcast storm degrades the system performance and affects the ARP learning. The number of sub-VLANs that are added to a super-VLAN cannot exceed 50.
- Run commit
The configuration is committed.
