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.

NOTE:

The following configurations are unsupported:

•HP PVST+ (default Spanning Tree setting) is NOT interoperable with Cisco Rapid PVST+.

•HP MSTP/RSTP (with mode set to either ‘mstp’ or ‘rstp’) is NOT interoperable with Cisco Rapid PVST+.

The following configurations are supported:•HP PVST+ (default Spanning Tree setting) is interoperable with Cisco PVST+.•HP MSTP/RSTP (with mode set to ‘mstp’) is interoperable with Cisco MST/RSTP.Common Internal Spanning Tree configurationCommand: /cfg/l2/mrst/cist[Common Internal Spanning Tree Menu]

The Common Internal Spanning Tree (CIST) provides compatibility with different MSTP regions and with devices running different Spanning Tree instances. It is equivalent to Spanning Tree Group 0.

The following table describes the commands used to configure Common Internal Spanning Tree Configuration Menu options.

Command	Description
brg	Displays the CIST Bridge Menu.
port <port number>	Displays the CIST Port Menu.
add <1-4095>	Adds VLANs to the CIST. Enter one VLAN per line, and press Enter to add the VLANs.
default	Resets all CIST parameters to their default values.
cur	Displays the current CIST configuration.
