3.2.2 Configuring a Super VLAN

You can configure multiple super VLANs for a switch. You can use the following
commands to specify a VLAN as a super VLAN. After a VLAN is configured as a super
VLAN, the configuration of its VLAN interface and IP address is the same as the
configuration for an ordinary VLAN.
Follow these steps to configure a VLAN as a super VLAN:
Enter system view
Enter VLAN view
Configure the current VLAN as a super VLAN
Caution:
You can not configure a VLAN which includes Ethernet ports as a super VLAN; and
after you configure a super VLAN, you cannot add any Ethernet port to it.
When a VLAN is configured as a super VLAN, proxy ARP function is automatically
enabled on the VLAN interface, and cannot be disabled.

3.2.3 Configuring a Sub VLAN

You can configure a sub VLAN just as configuring an ordinary VLAN. See the VLAN
part of this manual for details. The configuration commands are shown in the following
table.
Follow these steps to configure a sub VLAN:
Enter system view
Create a sub VLAN
Add Ethernet port(s) to the sub VLAN
