Spanning Tree Tab on SRW2048 Switches - MSTP Properties
MSTP operation maps VLANs into STP instances. Multiple Spanning Tree provides differing load balancing
scenario. For example, while port A is blocked in one STP instance, the same port is placed in the Forwarding
State in another STP instance.
In addition, packets assigned to various VLANs are transmitted along different paths within Multiple Spanning
Trees Regions (MST Regions). Regions are one or more Multiple Spanning Tree bridges by which frames can be
transmitted.
The MSTP Properties screen contains the following fields:
Region Name. This can be 1-32 characters in length and indicates user-defined MSTP region name.
Revision. Defines unsigned 16-bit number that identifies the current MST configuration revision. The revision
number is required as part of the MST configuration. The possible field range is 0-65535.
Max Hops. Defines 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. The possible field range is 1-40. The field default is 20
hops.
IST Master. Indicates the Internal Spanning Tree Master ID. The IST Master is the instance 0 root.
