DESCRIPTION
Configuration
Click Configuration to specify which STP mode you want to activate. Click RSTP to edit
RSTP settings on the Switch.
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 the bridge priority plus the 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). See
for information on
port states.
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 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.
