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
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.
5.10.2 Setting the Age Time Field
To set the Age Time, proceed as follows:
1. Use the arrow keys to highlight the Age Time field.
2. 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.
