Configure Mstp Format - Extreme Networks ExtremeWare XOS Command Reference Manual

ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
STP Commands

configure mstp format

configure mstp format <format_identifier>
Description
Configures the number used to identify the MSTP BPDUs sent in the MSTP region.
Syntax Description
format_identifier
Default
The default value used to identify the MSTP BPDU is 0.
Usage Guidelines
For a switch to be part of an MSTP region, you must configure each switch in the region with the same
MSTP configuration attributes, also known as MSTP region identifiers. These identifiers consist of the
following:
Region Name—The name of the MSTP region.
●
Format Selector—The number used to identify the format of MSTP BPDUs. The default is 0.
●
Revision Level—This identifier is reserved for future use; however, the switch uses and displays a
●
default of 3.
You can configure only one MSTP region on the switch at any given time.
The switches contained in a region transmit and receive BPDUs that contain information relevant to
only that MSTP region. By having devices look at the region identifiers, MSTP discovers the logical
boundary of a region.
If you have an active MSTP region, Extreme Networks recommends that you disable all active STPDs in
the region before modifying the value used to identify MSTP BPDUs on all participating switches.
Example
The following command configures the number 2 to identify the MSTP BPDUs sent within an MSTP
region:
configure mstp format 2
