Chapter 5: Local Management

Learning: The switch is learning the addresses on 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 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 

.

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:

Use the arrow keys to highlight the Type of STA field.

Use the SPACE bar to step to the appropriate setting of IEEE, DEC, 
or NONE. 

Use the arrow keys to highlight the SAVE command at the bottom of 
the screen.

Press ENTER. The message “SAVED OK” displays.

To set the Age Time, proceed as follows:

Use the arrow keys to highlight the Age Time field.

Type in the desired Age Time in increments of 10. The available Age 
Time range is 10 to 1,000,000 seconds with the default value being 
300 seconds.
