Defining Mstp Instance Settings - HP BladeSystem bc2000 - Blade PC User Manual

The MSTP Properties 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
specified instance root.
❏
Convert RSTP to MSTP Instance — Enables the device to translate Bridge Protocol
Data Units (BPDU) from both STP and RSTP enabled devices. The device translates the
incoming BPDU to MSTP, which then assigns the appropriate instance. Before
retransmitting, the device translates the MSTP BPDU to RSTP. This process allows
internal operation with MSTP and external operation with other Per-VLAN spanning
tree protocols to eliminate bridging multiple per-VLAN Root instances. The possible
field values are:
◆
Enable – Enables STP to MSTP/MSTP to STP conversion. This is the default.
◆
Disable – Disables STP to MSTP/MSTP to STP conversion.

Defining MSTP Instance Settings

MSTP maps VLANs into STP instances. Packets assigned to various VLANs are transmitted
along different paths within Multiple Spanning Tree Regions (MST Regions). Regions are one or
more Multiple Spanning Tree bridges by which frames can be transmitted. In configuring MSTP,
the MST region to which the device belongs is defined. A configuration consists of the name,
revision, and region to which the device belongs.
Network administrators can define the MSTP instance settings using the MSTP Instance Settings
page.
