The VLAN interface IP address in the above table is the IP address of the associated super VLAN.
For more information about the local-proxy-arp enable command and the local proxy ARP function,
refer to ARP Configuration in the Layer 3 - IP Services Configuration Guide.
You cannot configure a super VLAN as the guest VLAN for a port, and vice versa. For more
information about guest VLAN, refer to 802.1X Configuration in the Security Configuration Guide.
You can configure Layer 2 multicast for a super VLAN. However, the configuration cannot take
effect.
You can configure DHCP, Layer 3 multicast, dynamic routing, and NAT for the VLAN interface of a
super VLAN. However, only DHCP can take effect.
Configuring VRRP for the VLAN interface of a super VLAN affects network performance.
Therefore, you are recommended not to configure this function in normal cases.

Super VLAN Configuration Example
Network requirements
Create super VLAN 10, and configure its VLAN interface IP address as 10.0.0.1/24.
Create the sub-VLANs VLAN 2, VLAN 3, and VLAN 5.
Assign GigabitEthernet 2/0/1 and GigabitEthernet 2/0/2 to VLAN 2, GigabitEthernet 2/0/3 and
GigabitEthernet 2/0/4 to VLAN 3, and GigabitEthernet 2/0/5 and GigabitEthernet 2/0/6 to VLAN 5.
The sub-VLANs are isolated at Layer 2 but connected at Layer 3.
