Learning: The switch is learning the network address of this interface.
The switch enters the learning state when the Transparent Database is
created (during start-up or after being deleted), or when the Spanning
Tree Algorithm detects a network topology change.
Forwarding: The switch is on line 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 5.18.3.
[1-8], [9-16], [17-21] (Navigation Field)
The Switch Configuration screen can only show the configuration for
eight ports at a time. When the specific Navigation field is available, it
allows the user to view the Switch Configuration for ports 1 through 8,
ports 9 through 16, or ports 17 through 21. Once this field is highlighted,
press the ENTER key to go to the desired screen.
5.18.1 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 (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” is displayed.
