Note: This screen is only available after you activate RSTP on the Switch.
Figure 72
Advanced Application > Spanning Tree Protocol > Status: RSTP
The following table describes the labels in this screen.
Table 31
Advanced Application > Spanning Tree Protocol > Status: RSTP
LABEL
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 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) the 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).
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.
