switch_a(config-if)#
Bridge-Group Instance Priority:
1. Command Mode: Interface mode
Logon to Configure Mode (Configure Terminal Mode).
Then logon to Interface mode.
fe1 means port 1.
The switch_a(config-if)# prompt will show on the screen.
switch_a(config)#interface fe1
switch_a(config-if)#
2. Usage:
Use this command to set the port priority for a bridge group. The Multiple
Spanning Tree Protocol uses port priority as a tiebreaker to determine
which port should forward frames for a particular instance on a LAN, or
which port should be the root port for an instance. A lower value implies a
better priority. In the case of the same priority, the interface index will
serve as the tiebreaker, with the lower-numbered interface being preferred
over others. The permitted range is 0-240. The priority values can only be
set in increments of 16.
3. Command Syntax:
bridge GROUP instance INSTANCE_ID priority PRIORITY
GROUP <1-1> Specify the bridge-group ID.
INSTANCE_ID <1-15> Specify the instance ID.
PRIORITY <0-240> Specify the port priority in a range of <0-240>.
4. Example:
The following example sets the port priority (121) for Multiple Spanning
Tree instance (3) to a port (fe1) in bridge GROUP (1):
switch_a(config)#interface fe1
switch_a(config-if)#bridge-group 1 instance 3 priority 121
switch_a(config-if)#
Bridge-Group Instance Path-Cost:
1. Command Mode: Interface mode
Logon to Configure Mode (Configure Terminal Mode).
Then logon to Interface mode.
fe1 means port 1.
The switch_a(config-if)# prompt will show on the screen.
switch_a(config)#interface fe1
