Spanning Tree
The Switch supports 801.2d Spanning Tree Protocol, which allows you to create alternative paths (with multiple switches
or other types of bridges) in your network. See the Spanning Tree Algorithm section of the “Switch Management
Concepts ” chapter for a detailed explanation.

The information above is described as follows:
♦ Spanning Tree Protocol Status Displays the current Spanning Tree Protocol setting.
♦ Time Since Last Topology Change Displays the last time changes were made to the network topology. These
changes usually occur when backup paths are activated due to primary path failures.
♦ Topology Change Count Displays the number of times (since the current management session with the device
was started) changes were made to the network topology. Changes usually occur on the network when backup paths are
activated.
♦ MAC Address Displays the MAC address of the switch acting as the root bridge.
♦ Path Cost Displays the cost for the path between the Switch and the root bridge. If the Switch is the root bridge, then
the path cost is zero.
