3.1.3 subvlan

Syntax
subvlan vlan-list
undo subvlan [ vlan-list ]
View
VLAN view of the super VLAN
Parameter
vlan-list: List of sub VLANs, provided in the format of vlan-list = { vlan-id [ to
vlan-id ] }&<1-10>, where the vlan-id is the VLAN ID of a sub VLAN, and the &<1-10>
means you can specify ten sub VLANs or sub VLAN lists.
Description
Use the subvlan commmand to establish the mapping relationship between sub VLAN
and super VLAN.
Use the undo subvlan commmand to cancel the mapping relationship between sub
VLAN and super VLAN.
Without the argument vlan-list, the undo subvlan command can cancel the mapping
between all the sub VLANs and the isolate-user-VLAN. With this argument, the
command can cancel the mapping between the specified sub VLAN and the
isolate-user-VLAN.
Caution:
The sub VLAN must exist before you create mapping between the sub VLAN and
the super VLAN.
After establishing the mapping between the sub VLAN and the super VLAN, you can
still add (or delete) ports to (from) the sub VLAN.
A super VLAN can establish mappings with 1024 sub VLANs.
The system can create up to 1024 sub VLANs.
