The following table describes the labels in this screen.
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 46 on page 116 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.

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 bridge priority plus MAC address.
This ID is the same for Root and Our Bridge if the Switch is the root switch.
Hello Time
(second)
This is the time interval (in seconds) at which the root switch transmits a configuration
message. The root bridge determines Hello Time, Max Age and Forwarding Delay.
Max Age (second) This is the maximum time (in seconds) the Switch can wait without receiving a
configuration message before attempting to reconfigure.
