Defining Multiple
Spanning Tree
Multiple Spanning Tree (MSTP) provides differing load balancing
scenarios. For example, while port A is blocked in one STP instance, the
same port can be placed in the
Forwarding
state
in another STP instance.
The
Multiple STP Setup Page
contains information for defining global
MSTP settings, including region names, MSTP revisions, and maximum
hops.
To configure Multiple STP:
1
Click
Policy > Spanning Tree > Multiple STP > Setup
. The
Multiple STP
Setup Page
opens:
Figure 119
Multiple STP Setup
Page
The
Multiple STP Setup Page
contains the following fields:
■
Region Name
— User-defined STP region name.
■
Revision
— An unsigned 16-bit number that identifies the revision of
the current MSTP configuration. The revision number is required as
part of the MSTP configuration. The possible field range is 0-65535.
■
Max Hops
— Specifies 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
—
Identifies the Spanning Tree Master instance. The IST
Master is the specified instance root.
