Configure the priority for each port here.
Priority decides which port should be disabled when more than one port forms a loop in the
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 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.
Click this to create a new entry or to update an existing one.
This saves your changes to the Switch's run-time memory. The Switch loses this change if it is
turned off or loses power, so use the
changes to the non-volatile memory when you are done configuring.
Click to begin configuring this screen afresh.
