= { 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.

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.
