• Do not configure a VLAN as both a super VLAN and a guest VLAN, Auth-Fail VLAN, or critical
VLAN for a port, and vice versa. For more information about guest VLANs, Auth-Fail VLANs, and
critical VLANs, see Security Configuration Guide.
• Do not configure a VLAN as both a super VLAN and a MAC-based VLAN.
• Do not configure a VLAN as both a super VLAN and a sub-VLAN.
• You can configure Layer 2 multicast for super VLANs. However, the configuration does not take
effect because super VLANs do not have physical ports.
To configure a super VLAN:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter VLAN view. vlan vlan-id N/A
3. Configure the VLAN as a
super VLAN.
supervlan By default, a VLAN is not a super VLAN.
4. Associate the super VLAN
with the sub-VLANs.
subvlan vlan-id-list
By default, a super VLAN is not associated with any
sub-VLANs.
Make sure the sub-VLANs already exist before
associating them with a super VLAN.
Configuring a super VLAN interface
H3C recommends not configuring VRRP for the VLAN interface of a super VLAN because the
configuration affects network performance. For more information about VRRP, see High Availability
Configuration Guide.
To configure a super VLAN interface:
Step Command Remarks
1. Enter system view. system-view N/A
2. Create a VLAN
interface and enter its
view.
interface vlan-interface
vlan-interface-id The vlan-interface-id argument must be
the super VLAN ID.
3. Configure an IP
address for the VLAN
interface of the super
VLAN.
• Configure an IPv4 address:
ip address ip-address
{ mask-length | mask } [ sub ]
• Configure an IPv6 address:
ipv6 address { ipv6-address
prefix-length |
ipv6-address/prefix-length }
By default, no IP address is configured
for a VLAN interface.
