• Listening: The switch is not adding information to the Transparent
Database. The switch is monitoring the Bridge Protocol Data Unit
(BPDU) traffic while preparing to move from the learning to the
forwarding state.
• Forwarding: The switch is operating and this interface is forwarding
traffic.
• Blocking: This interface will not forward any traffic through the switch
because a loop condition has been detected by the STA.
Status (Toggle)
Allows the user to disable or enable a port by setting the status of the
listed interface to either ENABLED or DISABLED. To set the port status,
refer to Section 5.10.3.
5.10.1 Setting the STA
The Spanning Tree Algorithm (STA) setting allows the user to set the
method that the switches use to decide which is the controller (Root)
switch when two or more switches are in parallel. The available selections
are IEEE, DEC, and NONE.
To set the STA, proceed as follows:
1. Use the arrow keys to highlight the Type of STA field.
2. Use the SPACE bar to step to the appropriate setting of IEEE, DEC,
or NONE.
3. Use the arrow keys to highlight the SAVE command at the bottom of
the screen.
4. Press ENTER. The message “SAVED OK” displays.
