H3C S9500 Series Routing Switches
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.
3.2.2 Super VLAN Configuration Example
I. Network requirements
Super VLAN 10 and sub VLANs VLAN 2, VLAN 3 and VLAN 5 need to be created.
VLAN 2 contains ports 1 and 2; VLAN 3 contains ports 3 and 4; VLAN 5 contains ports
5 and 6. These sub VLANs are isolated at Layer 2. It is required that these sub VLANs
communicate with one another at Layer 3.
