3.4 Super VLAN Configuration Examples

3.4.1 Super VLAN Configuration Example

I. Network Requirements

Create super VLAN 10 and sub VLANs VLAN 2, VLAN 3, VLAN 5. Configure ports

Ethernet 1/0/1 and Ethernet 1/0/2 to belong to VLAN 2, Ethernet 1/0/3 and Ethernet

1/0/4 to belong to VLAN 3, and Ethernet 1/0/5 and Ethernet 1/0/6 to belong to VLAN 5.

Since Layer 2 isolation is implemented between VLANs, configure Layer 3 connectivity

between sub VLANs, and all sub VLANs use the Layer 3 interface of the super VLAN

(with the IP address being 10.110.1.1) as the gateway to communicate with the outside.

 Note:

By default, the proxy ARP function is enabled on the VLAN interface of the super VLAN,

and cannot be disabled.
