DESCRIPTION

Port

Select a port to configure.

 

 

Priority (1~255)

Enter the port’s priority rating.

 

Priority decides which port should be disabled when more than

 

one port forms a loop in a switch. Ports with a higher priority

 

numeric value are disabled first. The allowed range is between 0

 

and 255 and the default value is 128.

 

 

Cost (1~65535)

Enter the port’s path cost.

 

Path cost is the cost of transmitting a frame on to a LAN through

 

that port. It is recommended to assign this value according to the

 

speed of the bridge. The slower the media, the higher the cost-

 

see Table 23 on page 89 for more information.
