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 priority priority
no bridge-group bridge-group priority
• 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.
