Priority Configure the priority for each port here.
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.
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 60 on page 138 for more information.
