Description
Use the
isolate-user-vlan
command to associate an isolate-user-VLAN with the specified secondary
VLAN(s).
Use the
undo isolate-user-vlan
command to remove the association.
By default, an isolate-user-VLAN is not associated with any secondary VLAN. .
Note that:
z
To use the
isolate-user-vlan
command, each of the isolate-user-VLAN and the secondary VLAN(s)
must have at least one port which allows its isolate-user-VLAN or secondary VLAN to pass through.
The default VLAN of the port must be its isolate-user-VLAN or secondary VLAN.
z
The
undo isolate-user-vlan
command without the
secondary
secondary-vlan-id
parameter
specified removes the association between the specified isolate-user-VLAN and all its secondary
VLANs, while the
undo isolate-user-vlan
command with the
secondary
secondary-vlan-id
parameter specified only removes the association between the specified isolate-user-VLAN and
the specified secondary VLANs.
After associating an isolate-user-VLAN with the specified secondary VLANs, you cannot add/remove a
port to/from each involved VLAN or remove each involved VLAN. To do that, you must cancel the
association first.
