Redundancy

Be sure to physically connect your backup ports once your redundant circuit has been

!enabled!

CAUTION

To disable a circuit:

!

CAUTION

1.Use the drop-down list to display the appropriate circuit in the Current Circuit text box; note that the current status of the selected circuit (enabled or disabled) is displayed just below the Current Circuit text box.

2.Click Configure, and drag down to Disable to inactivate the currently selected circuit. The displayed status for the selected circuit will change to Disabled.

If you do not plan to re-enable the circuit, remember that all configured backup ports will remain disabled by management until they are manually re-enabled using the port menus from the Chassis View window (in Logical display mode). If you do decide to re-enable your backup ports, be sure to disconnect redundant network links before doing so, or multiple data loops will result.

Testing the Circuits

The circuit test checks the current status of every port link, both primary and backup, by polling the physical addresses in each circuit’s Polling Addresses list through each port configured as part of the circuit. This test can be performed at a pre-determined time or date, or manually at any time.

If the test detects any problems with the ports on a circuit, whether active or backup, it will list the circuit and its problem ports in the alarm logging facility. (Refer to the Alarm and Event Handling User’s Guide for your Enterasys management application for more information.)

The testing begins at each circuit’s currently active port; all ports are tested in sequence. Once testing is finished, the circuits will be reset so that the port designated as Primary will become the active port; if the primary port is not operational, the next operational backup port will be activated.

NOTE

A primary port that has failed, then been repaired, is not returned to active status until the circuit test is run, unless all other backup ports on the circuit have failed in the interim.
