DESCRIPTION

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 25 on page 122 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.

DESCRIPTION

Configuration

Click Configuration to specify which STP mode you want to activate. Click

 

RSTP to edit RSTP settings on the Switch.

 

 

Bridge

Root refers to the base of the spanning tree (the root bridge). Our Bridge is

 

this Switch. This Switch may also be the root bridge.

 

 

Bridge ID

This is the unique identifier for this bridge, consisting of the bridge priority plus

 

the MAC address. This ID is the same for Root and Our Bridge if the Switch is

 

the root switch.

 

 

Hello Time

This is the time interval (in seconds) at which the root switch transmits a
(second)

configuration message. The root bridge determines Hello Time, Max Age and

 

Forwarding Delay.

 

 

Max Age (second)This is the maximum time (in seconds) a switch can wait without receiving a

 

configuration message before attempting to reconfigure.
