Operation
Enter system view
Enter VLAN view
Configure the current VLAN
as a super VLAN
CAUTION: You can not configure a VLAN which includes Ethernet ports as a super
VLAN; and after you configure a super VLAN, you cannot add any Ethernet port to
it.
You can configure a sub VLAN just as configuring an ordinary VLAN. See "VLAN
Configuration" on page 95 for details. The configuration commands are shown in
the following table.
Table 70 Configure a sub VLAN
Operation
Enter system view
Create a sub VLAN
Add an Ethernet port to the
sub VLAN
CAUTION: The port command is only used to add the access port to a sub VLAN.
If you want to add a trunk port or a hybrid port to a sub VLAN, you must execute
the port trunk permit vlan command and the port hybrid vlan command in
Ethernet port view. Refer to "Configuring a Trunk-Port-Based VLAN" on page 98
and "Configuring a Hybrid-Port-Based VLAN" on page 98.
Note that you can add multiple ports (except the uplink port) for a sub VLAN.
You can use the following commands to establish the mapping between a super
VLAN and a sub VLAN.
Table 71 Configure the mapping between a super VLAN and a sub VLAN
Operation
Enter system view
Enter VLAN view of the super
VLAN
Establish the mapping
between a super VLAN and a
sub VLAN
CAUTION:
The sub VLAN must exist before you create mapping between the sub VLAN
■
and the super VLAN.
When you establish mapping between the super VLAN and the sub VLAN, if a
■
VLAN interface is configured for the sub VLAN, the system will prompt you to
delete the interface to establish the mapping successfully.
