In the Suggestion dialog box, click OK.
Step 3
In the Create MS-SPRing dialog box, set the MS-SPRing properties:
Step 4
Ring Type—Choose four-fiber.
•
Ring Name—Assign a ring name. You must use the same ring name for each node in the
•
MS-SPRing. Any alphanumeric character string is permissible, and upper and lower case letters can
be combined. Do not use the character string "All" in either upper or lower case letters. This is a
TL1 keyword and will be rejected. Do not choose a name that is already assigned to another
MS-SPRing.
Node ID—Choose a Node ID from the drop-down list (0 through 31). The Node ID identifies the
•
node to the MS-SPRing. Nodes in the same MS-SPRing must have unique Node IDs.
Reversion time—Set the amount of time that will pass before the traffic reverts to the original
•
working path. The default is 5 minutes. All nodes in an MS-SPRing must have the same reversion
time setting.
West Line—Assign the west MS-SPRing port for the node from the drop-down list.
•
Note
East Line—Assign the east MS-SPRing port for the node from the drop-down list.
•
Span Reversion—Set the amount of time that will pass before the traffic reverts to the original
•
working path following a span reversion. The default is 5 minutes. Span reversions can be set to
Never. If you set a reversion time, the times must be the same for both ends of the span. That is, if
Node A's west fiber is connected to Node B's east port, the Node A west span reversion time must
be the same as the Node B east span reversion time. To avoid reversion time mismatches, Cisco
recommends that you use the same span reversion time throughout the ring.
West Protect—Assign the west MS-SPRing port that will connect to the west protect fiber from the
•
drop-down list.
East Protect—Assign the east MS-SPRing port that will connect to the east protect fiber from the
•
drop-down list.
Click OK.

The east and west ports must match the fiber connections and DCC terminations set up in
the "NTP-D40 Provision MS-SPRing Nodes" procedure on page
Some or all of the following alarms will appear until all the MS-SPRing nodes are provisioned:
E-W-MISMATCH, RING-MISMATCH, APSCIMP, APSCDFLTK, and MS-SPRINGOSYNC.
The alarms will clear after you configure all the nodes in the MS-SPRing.
