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 | 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. |
|
|
Forwarding Delay | This is the time (in seconds) the root switch will wait before changing states (that |
(second) | is, listening to learning to forwarding). |
| Note: The listening state does not exist in RSTP. |
|
|
Cost to Bridge | This is the path cost from the root port on this Switch to the root switch. |
|
|
Port ID | This is the priority and number of the port on the Switch through which this Switch |
