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) Forwarding Delay (second) This is the maximum time (in seconds) a switch can wait without receiving a configuration message before attempting to reconfigure. This is the time (in seconds) the root switch will wait before changing states (that is, listening to learning to forwarding). See Section 13.1.3 on page 125 for information on port states. Cost to Bridge Port ID Topology Changed Times Time Since Last Change Note: The listening state does not exist in RSTP. This is the path cost from the root port on this Switch to the root switch. 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. This is the number of times the spanning tree has been reconfigured. This is the time since the spanning tree was last reconfigured. 132 ES3500 Series User's Guide

Rapid Spanning Tree Protocol Status
Click
Advanced Application
>
Spanning Tree Protocol
in the navigation panel to display the
status screen as shown next. See
Section 13.1 on page 124
for more information on RSTP.
Note: This screen is only available after you activate RSTP on the Switch.
Figure 65
Advanced Application > Spanning Tree Protocol > Status: RSTP
The following table describes the labels in this screen.
Table 35
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 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
Section 13.1.3 on page 125
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.
