NTP-D159 Modify an MS-SPRing
Step 1 Complete the “DLP-D60 Log into CTC” task on page 17-49 at a node in the MS-SPRing that you want
to modify. If you are already logged in, continue with Step 2.
Step 2 Complete the “DLP-D298 Check the Network for Alarms and Conditions” task on page 19-83 for
instructions.
Note Some or all of the following alarms appear during MS-SPRing setup: E-W MISMATCH,
RING MISMATCH, APSCIMP, APSDFLTK, and MSSP-OSYNC. The alarms clear after you
configure all the nodes in the MS-SPRing. For definitions of these alarms, see the
Cisco ONS 15454 SDH Troubleshooting Guide.
Step 3 To change the MS-SPRing ring name or the ring or span reversion times, complete the following steps.
If you want to change a node ID, continue with Step 4.
a. Switch to network view and click the Provisioning > MS-SPRing tabs.
b. Click the MS-SPRing you want to modify and click Edit.
c. In the MS-SPRing window, change any of the following:
– Ring Name—If needed, change the MS-SPRing ring name. The name can be from 1 to 6
characters in length. The alphanumeric character strings that can be used are 0 to 9 and A to Z.
You can combine numbers and letters and use upper or lower case letters. Do not use the
character string “All” in either upper or lower case letters because it is a TL1 keyword. Do not
choose a name that is already assigned to another MS-SPRing.
– Reversion time—If needed, change the amount of time that will pass before the traffic reverts
to the original working path after a ring switch.
– Span Reversion—(Four-fiber MS-SPRings only) If needed, change the amount of time that will
pass before the traffic reverts to the original working path after a span switch.
d. Click Apply.
e. If you changed the ring name, the MS-SPRing window closes automatically. If you only changed a
reversion time, close the window by choosing Close from the File menu.
Step 4 As needed complete the “DLP-D24 Change an MS-SPRing Node ID” task on page 17-19; otherwise,
continue with Step 5.
Step 5 In network view, verify the following:
• A green span line appears between all MS-SPRing nodes.
Purpose This procedure changes an MS-SPRing ring ID, node ID, or ring and span
reversion times.
