4.Choose SAVE and press Enter to let any changes take effect. The status variables shown are:

♦Time Since Topology Change The last time that changes were made to the network topology, such as might occur when a backup path is activated due to a primary path failure.

♦Topology Change Count How many times the network bridge topology has changed since the DES-2212 was turned on.

♦Designated Root The MAC (Ethernet) address of the bridge/switch on the network that has been chosen as the STA root.

♦Root Cost Displays the cost for the path between this switch and the root bridge. If the DES-2212 is the root bridge, then this field displays zero.

♦Root Port Identifies the port (on this bridge) that offers the least path cost from this bridge to the root bridge. In the event of a network loop, data packets will pass through the root port.

♦Max Age (sec) Indicates the maximum age of spanning tree information learned from the network (on any port) before it is discarded.
