LABEL DESCRIPTION
Configuration Click Configuration to configure RSTP settings. Refer to Section 11.3 on page
104 .
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) a switch can wait without receiving a
configuration message before attempting to reconfigure.
Forwarding Delay
(second)
This is the time (in seconds) the root switch will wait before changing states (that
is, listening to learning to forwarding).
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
must communicate with the root of the Spanning Tree.
Topology
Changed Times
This is the number of times the spanning tree has been reconfigured.
Time Since Last
Change
This is the time since the spanning tree was last reconfigured.
