Cisco Cisco Aironet 340 Ethernet Bridges Guia Do Utilizador

The priority option is only used when two or more repeaters are con-
nected to the same LAN for redundancy and you want to select which 
one will forward the packets. The port assigned the lowest priority value 
will be the one to forward. The priority range is from 0 to ff hex with a 
default setting of 80.

The value for the cost option is added to the root cost field from any 
received configuration messages to determine if the port has the least 
cost path to the root. Cost values can be set for 65535 or less with a 
default value is 100. 

The larger the cost value, the more likely the port will be a backup for 
another active port on its LAN. If there is no active port, it is likely the 
LAN will be a leaf of the infrastructure tree or a less used LAN in the 
tree. 

The rport, rpriority and rcost options are used to configure the ports of 
active and connected repeaters in the root’s radio tree.

These options are identical to the port, priority and cost options 
described except when the values are entered, you will be prompted for 
the applicable port number. The port number can be obtained from the 
port ID field on the Protocol Status Display screen.
