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 configuration 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 CIST commands. Table 104 CIST Configuration commands Command Description spanning-tree mstp cist- Adds VLANs to the CIST. Enter one VLAN per line, and press Enter to add the VLANs. add-vlan Command mode: Global configuration default spanning-tree mstp cist Resets all CIST parameters to their default values. Command mode: Global configuration show spanning-tree mstp Displays the current CIST configuration. cist Command mode: All CIST bridge configuration CIST bridge parameters are used only when the switch is in MSTP mode. CIST parameters do not affect operation of STP/PVST. The following table describes the commands used to configure CIST Bridge Configuration commands. Table 105 CIST Bridge Configuration commands Command Description spanning-tree mstp cistbridge priority {} 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 "Bridge Spanning Tree configuration" section for more information. Command mode: Global configuration spanning-tree mstp cistbridge maximum-age {} 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 "Bridge Spanning Tree configuration" section for more information. Command mode: Global configuration spanning-tree mstp cistbridge forward-delay {} 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 "Bridge Spanning Tree configuration" section for more information.

Common Internal Spanning Tree configuration
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 CIST commands.
Table 104

Enter
to add the VLANs.
Command mode
: Global configuration
default spanning-tree

CIST bridge configuration
CIST bridge parameters are used only when the switch is in MSTP mode. CIST parameters do not affect operation of
STP/PVST.
The following table describes the commands used to configure CIST Bridge Configuration commands.
Table 105
CIST Bridge Configuration commands
Command
Description
spanning-tree mstp cist-
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 "Bridge Spanning Tree
configuration" section for more information.
Command mode
: Global configuration
spanning-tree mstp cist-
bridge maximum-age {
<6-40>
}
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 "Bridge Spanning Tree
configuration" section for more information.
Command mode
: Global configuration
spanning-tree mstp cist-
bridge forward-delay {
<4-30>
}
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 "Bridge Spanning Tree
configuration" section for more information.
