HP ProLiant BL p-Class GbE2 Interconnect Switch supports the IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) and IEEE 802.1s Multiple Spanning Tree Protocol (MSTP). MSTP allows you to map many VLANs to a small number of spanning tree groups, each with its own topology.

You can configure up to 32 spanning tree groups on the switch. MRST is turned off by default.

NOTE: When Multiple Spanning Tree is turned on, VLAN 1 is moved from Spanning Tree Group 1 to the Common Internal Spanning Tree (CIST). When Multiple Spanning Tree is turned off, VLAN 1 is moved back to Spanning Tree Group 1.

The following table describes the Multiple Spanning Tree Configuration Menu options.

Table 114 Multiple Spanning Tree Configuration Menu options

Command

Description

 

 

 

cist

Displays the Common Internal Spanning Tree (CIST) Menu.

 

 

 

name <1-32 characters>

Configures a name for the MSTP region. All devices within a MSTP region must

 

have the same region name.

 

 

 

rev <0-65535>

Configures the revision level for the MSTP region. The revision level is used as a

 

numerical identifier for the region. All devices within a MSTP region must have the

 

same revision level number. The range is 0-65535.

 

 

 

maxhop <4-60>

Configures the maximum number of bridge hops a packet may to traverse before

 

it is dropped. The range is from 4 to 60 hops. The default is 20.

 

 

 

mode rstpmstp

Selects either Rapid Spanning Tree mode (rstp) or Multiple Spanning Tree mode

 

(mstp). The default mode is RSTP.

 

 

 

on

Globally turn RSTP/MSTP ON.

 

 

NOTE: When RSTP is turned on, the configuration parameters for STP group 1 apply to RSTP.

 

 

 

off

Globally turn RSTP/MSTP OFF.

 

 

 

cur

Displays the current RSTP/MSTP configuration.

 

 

 

 

 

 

NOTE:

•IEEE 802.1w standard-based RSTP implementation runs on one STG (i.e. same as one spanning tree instance) only. As a result, if ‘rstp’ mode is selected under the /cfg/mrst/mode command, then only a single RSTP instance (default for STG 1) is supported for all VLANs, including the Default VLAN 1.

•If multiple spanning tree instances are required, then select ‘mstp’ mode so that multiple VLANs are handled by multiple spanning tree instances, as specified by IEEE 802.1s standard-based MSTP implementation.

•IEEE 802.1s MSTP supports rapid convergence using IEEE 802.1w RSTP.•PVST+ does not support rapid convergence in current versions.
