Chapter 5: Local Management5-382E43-51/2E43-51R User’s GuideLearning: The switch is learning the addresses on this interface. Theswitch enters the learning state when the Transparent Database is created(during start-up or after being deleted), or when the Spanning TreeAlgorithm detects a network topology change.Forwarding: The switch is operating and this interface is forwardingtraffic.Blocking: This interface will not forward any traffic through the switchbecause 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 thelisted interface to either ENABLED or DISABLED. To set the port status,refer to Section 5.10.3.5.10.1 Setting the STAThe Spanning Tree Algorithm (STA) setting allows the user to set themethod that the switches use to decide which is the controller (Root)switch when two or more switches are in parallel. The available selectionsare 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 ofthe screen.4. Press ENTER. The message “SAVED OK” displays.5.10.2 Setting the Age Time FieldTo 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 AgeTime range is 10 to 1,000,000 seconds with the default value being300 seconds.
