Modifying a Protected Ports VLAN
Note the following before performing this procedure:
 To modify a protected ports VLAN, you have to recreate it. You must
reselect the uplink port(s) and reassign the ports to the groups. To
make the process easier, Allied Telesis recommends displaying the
details of the VLAN before performing this procedure, and writing down
on paper the current configuration (i.e., uplink port and port to group
assignments). This information will make it easier for you to recreate
the VLAN, with the necessary modifications, when you perform the
procedure. To display a VLAN’s configuration, refer to “Displaying a
Protected Ports VLAN” on page 524.
 To add untagged ports, the ports must be untagged members of the
Default_VLAN or a port-based or tagged VLAN. They can not be
members of another protected ports VLAN.
 An untagged port removed from a VLAN is automatically returned to
the Default_VLAN.
Note
You need to know the VID of a VLAN to modify it. To view VLAN
VIDs, refer to “Displaying a Protected Ports VLAN” on page 524.
