Displaying And Maintaining Super Vlan; Super Vlan Configuration Example - 3Com S7906E Configuration Manual

To do...
Enter VLAN interface view
Configure the IP address of the
VLAN interface
Enable local proxy ARP
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 Commands and ARP Configuration in the IP Services Volume.
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 Volume.
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.
Use the command...
interface vlan-interface
vlan-interface-id
ip address ip-address { mask |
mask-length } [ sub ]
local-proxy-arp enable
Use the command...
display supervlan [ supervlan-id ]
