priority.

Example: Setting the priority for port 1/2 of instance1 to 32. Switch(Config)#interface ethernet 1/2 Switch(Config-Ethernet1/2)#spanning-tree mst 1 port-priority 32

10.2.2.17spanning-tree mst priority

Command: spanning-tree mst <instance-id>priority <bridge-priority>no spanning-tree mst <instance-id>priority

Function: Sets the switch bridge priority of the specified instance; the “no spanning-tree mst” restores the default priority value for the switch on the specified instance.

Parameters: <instance-id>is the instance ID of the designated instance ranging from 0 – 48; <port-priority>is the port priority value, which is multiples of 4096 between 0 to 61440, i.e., 0, 4096, 8192,… 61440.

Command mode: Global Mode

Default: The default switch priority is 32768.

Usage Guide: Bridge ID of the specified instance can be changed by setting switch priority, therefore affecting the root bridge and designated port election for that instance. A smaller switch bridge priority value means a higher priority.

Example: The default switch instance2 priority is 4096. Switch(Config)#spanning-tree mst 2 priority 4096

10.2.2.18spanning-tree portfast

Command: spanning-tree portfast no spanning-tree portfast

Function: Sets the current port as an edge port; the “no spanning-tree portfast” command sets the current port as a non-edge port.

Command mode: Port configuration Mode

Default: All ports are non-edge ports on initial MSTP start.

Usage Guide: When a port is configured as an edge port, it can switch from Discarding status to Forwarding status instantly without the forward delay. Once BPDU frames are received on an edge port, the port changes to a non-edge port automatically.

Example: Configuring port 1/5-6 to be edge ports. Switch(Config)#interface ethernet 15-6 Switch(Config-Port-Range)#spanning-tree portfast
