Description
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.
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.
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.
