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-
