62 CHAPTER 8: SUPER VLAN CONFIGURATION
c
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.
