Default Level

Parameters
reference-instance instance-id-list: Specifies the MSTIs to be referenced in the form of instance-id-list
= { instance-id [ to instance-id ] }&<1-10>, where the range of the instance-id argument is as specified
in the command configuring MSTIs and &<1-10> indicates that you can provide up to ten MSTIs or
MSTI lists.
Description
Use the protected-vlan command to configure protected VLANs for a smart link group by referencing
MSTIs. You can use the display stp region-configuration command to view the VLANs mapped to
the referenced MSTIs.
Use the undo protected-vlan command to remove the specified protected VLANs from a smart link
group by referencing the specified MSTIs. If no MSTI is specified, all the protected VLANs of the smart
link group are removed.
By default, no protected VLAN is configured for a smart link group.
Note that:
Before assigning ports to a smart link group, configure protected VLANs for the smart link group.
You can remove all protected VLANs from a smart link group when the group is empty but not
after a member port is assigned to it.
Removing a smart link group also removes its protected VLANs.
If the VLAN(s) mapped to a referenced MSTI changes, the protected VLAN(s) change
accordingly.
The VLANs that the member ports of a smart link group belong to must be configured as the
protected VLANs of the smart link group.
Related commands: smart-link group, display stp region-configuration in MSTP Commands in the

Examples
# Configure the VLANs mapped to MSTIs 1 through 10 and MSTI 12 as the protected VLANs of smart
link group 1.
