DLP- D217 MS-SPRing Exercise Ring Test

Step 5 Exercise the east port:

a.Right-click the east port of any MS-SPRing node and choose Set East Protection Operation.

Note For two fiber MS-SPRings, the squares on the node icons represent the MS-SPRing working and protect channels. You can right-click either channel. For four-fiber MS-SPRings, the squares represent ports. Right-click either the working or protect ports.

b.In the Set East Protection Operation dialog box, choose EXERCISE RING from the drop-down list.

c.Click OK.

d.In the Confirm MS-SPRing Operation dialog box, click Yes.

On the network view graphic, an E appears on the MS-SPRing channel where you invoked the exercise. The E will appear for 10 to 15 seconds, then disappear.

Step 6 In the CTC window, click the History tab. Verify that an EXERCISE-RING (Exercising Ring Successfully) condition appears for the node where you exercised the ring. Other conditions that appear include EXERCISE-RING-REQ, KB-PASSTHR, and FE-EXERCISING-RING.

If you do not see any MS-SPRing exercise conditions, click the Filter button and verify that filtering is not turned on. Also, check that alarms and conditions are not suppressed for a node or MS-SPRing drop cards. See the “NTP-D72 Suppress Alarms or Discontinue Alarm Suppression” procedure on page 9-7for more information.

Step 7 Click the Alarms tab.

a.Verify that the alarm filter is not on. See the “DLP-D227 Disable Alarm Filtering” task on page 19-26as necessary.

b.Verify that no unexplained alarms appear on the network. If unexplained alarms appear, resolve them before continuing. Refer to the Cisco ONS 15454 SDH Troubleshooting Guide if necessary.

Step 8 From the File menu, choose Close to close the MS-SPRing window.

Step 9 Return to your originating procedure (NTP).
