DESCRIPTION

Active

Select this check box to activate RSTP on this port.

 

 

Edge

Select this check box to configure a port as an edge port when it is

 

directly attached to a computer. An edge port changes its initial STP

 

port state from blocking state to forwarding state immediately without

 

going through listening and learning states right after the port is

 

configured as an edge port or when its link status changes.

 

Note: An edge port becomes a non-edge port as soon as it receives

 

a Bridge Protocol Data Unit (BPDU).

 

 

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 26 on

 

page 148 for more information.

 

 

Apply

Click Apply to save your changes to the Switch’s run-time memory. The

 

Switch loses these changes if it is turned off or loses power, so use the

 

Save link on the top navigation panel to save your changes to the non-

 

volatile memory when you are done configuring.

 

 

Cancel

Click Cancel to begin configuring this screen afresh.
