Creating a Super-VLAN
Context
A super-VLAN consists of several sub-VLANs. No physical interface can be added to a super-VLAN, but a VLANIF interface can be configured for the super-VLAN and an IP address can be assigned to the VLANIF interface.
Procedure
- Run:
system-viewThe 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 each sub-VLAN ID.
- Run:
aggregate-vlanA 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 any sub-VLANs to a super-VLAN, ensure that they are not configured with VLANIF interfaces.
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.
The super-VLAN cannot be used with Layer 3 multicast.
