ONFIGURATION
CAUTION:
A Super VLAN cannot contain ports.
After you set the VLAN type to super VLAN, the ARP proxy is automatically 
enabled on the VLAN port, and you do not need to configure the proxy.
When a super VLAN exists, the ARP proxy should be enabled on the 
corresponding VLAN port.
The default VLAN cannot be set to a super VLAN.
You can add multiple ports (non-uplink port) to each sub VLAN.
You cannot configure a virtual port for a sub VLAN.
If the undo subvlan command does not include vlan-id, the mapping 
relationship between all sub VLANs and specified super VLANs is removed; if 
the undo subvlan command includes vlan-id, the mapping relationship 
between the specified sub VLANs and specified super VLANs is removed.
In Super VLAN configuration, do not enable multicast VLAN and 
IGMP-snooping.
Super VLAN does not support VRRP.
