Command Syntax and Usage

prior <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.

mxage <6-40 seconds>

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 reconfig- ures the MSTP network. The range is 6 to 40 seconds, and the default is 20 seconds.

fwd <4-30 seconds>

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 learn- ing state and from the learning state to the forwarding state. The range is 4 to 30 seconds, and the default is 15 seconds.

cur
