Configuring sub-VLANs
To configure multiple sub-VLANs, repeat these steps.
To configure a sub-VLAN:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Create a sub-VLAN and
enter VLAN view.
vlan vlan-id
If the specified VLAN already exists, this
command enters VLAN view only.
Configuring a super VLAN
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Enter VLAN view.
vlan vlan-id
If the specified VLAN does not exist,
this command creates the VLAN
first, and then enters VLAN view.
3. Configure the VLAN as a
super VLAN.
supervlan
By default, a super VLAN is not
configured.
Do not configure a VLAN as a super
VLAN and a sub VLAN at the same
time.
4. Associate the super VLAN
with the specified sub-VLANs.
subvlan vlan-list
VLANs specified by vlan-list must be
the sub-VLANs configured earlier.
Configuring a VLAN interface for the super VLAN
Configuration restrictions and guidelines
• Configure the IP address of the VLAN interface with that of the corresponding super VLAN.
• You cannot configure a super VLAN as the guest VLAN for a port, and vice versa. For more
information about guest VLANs, see Security Configuration Guide.
• You can configure Layer 2 multicast for a super VLAN, but the configuration is ineffective.
• You can configure DHCP, Layer 3 multicast, dynamic routing, and NAT for the VLAN interface of a
super VLAN. However, only DHCP takes effect.
• HP recommends not configuring VRRP for the VLAN interface of a super VLAN, because it affects
network performance. For more information about VRRP, see High Availability Configuration
Guide.
