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+, RSTP, or PVRST.
Table 160 CIST Bridge Configuration Commands
Command Syntax and Usage
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, in steps of 4096 (0, 4096, 8192...), and the default value is 61440.
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.
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.
