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 Bridge Configuration
To display the following form, select Layer 2 > MSTP/RSTP > CIST-Bridge.
The 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 Common Internal Spanning Tree Bridge Configuration controls:
Table 115 Common Internal Spanning Tree Bridge Configuration controls
Control Description
Bridge Priority (0-65535) Configures the CIST bridge priority. The bridge priority parameter controls which
bridge on the network is the MSTP root bridge. To make this switch the root bridge,
configure the bridge priority lower than all other switches and bridges on your
network. The lower the value, the higher the bridge priority. The range is 0 to
65535, and the default is 32768.
This command does not apply to RSTP. See the "Switch Spanning Tree Group
Configuration" section for more information.
Max. Age (6-40 secs) Configures the CIST bridge maximum age. The maximum age parameter specifies
the maximum time the bridge waits without receiving a configuration bridge
protocol data unit before it reconfigures the MSTP network. The range is 6 to 40
seconds, and the default is 20 seconds.
This command does not apply to RSTP. See the "Switch Spanning Tree Group
Configuration" section for more information.
Forward Delay (4-30 secs) Configures the CIST bridge forward delay parameter. The forward delay parameter
specifies the amount of time that a bridge port has to wait before it changes from
the listening state to the learning state and from the learning state to the forwarding
state. The range is 4 to 30 seconds, and the default is 15 seconds.
This command does not apply to RSTP. See the "Switch Spanning Tree Group
Configuration" section for more information.
