Command Usage 

• This command is used by the spanning-tree algorithm to determine the 

best path between devices. Therefore, lower values should be assigned 
to ports attached to faster media, and higher values assigned to ports 
with slower media. 

• Path cost takes precedence over port priority.

Example 

bridge-group priority

Use this command to configure the priority for the specified port. Use the 

no

 form to restore the default.

Syntax 

bridge-group

•

bridge-group

 - Bridge group index (bridge 1). 

•

priority

 - The priority for a port. (Range: 0-255) 

Default Setting 

128

Command Mode 

Interface Configuration (Ethernet, Port Channel)

Command Usage 

• This command defines the priority for the use of a port in the 

spanning-tree algorithm. If the path cost for all ports on a switch are 
the same, the port with the highest priority (that is, lowest value) will be 
configured as an active link in the spanning tree. 

• Where more than one port is assigned the highest priority, the port with 

lowest numeric identifier will be enabled.
