MSTP Properties
MSTP maps VLANs into MSTP instances, using various load balancing
scenarios. As a result of this partitioning into instances, a port can be placed
in Blocking State in one STP instance and can be placed in the Forwarding
State in another STP instance.
Packets are transmitted along the MSTP instances that their VLANs are
associated with in a Multiple Spanning Tree Region. A MST region consists
of adjacent MSTP bridges that have the same VLANs to MST instances
association.
To set an MSTP region:
1 Click Network Administration > Spanning Tree and LAG > Spanning
Tree > MSTP Properties
2 Click Edit and enter the following fields:
– Region Name — Enter the user-defined MSTP region name.
– Revision — Enter the unsigned 16-bit number that identifies the

– Max Hops (1-40) — Enter the total number of hops that occur in a
specific region before the BPDU is discarded. Once the BPDU is
discarded, the port information is aged out.
– IST Master — Displays the Internal Spanning Tree Master ID. The
IST Master is the instance 0 root.
