NTP-A159 Modify a BLSR
Note Some or all of the following alarms appear during BLSR setup: E-W MISMATCH, RING
MISMATCH, APSCIMP, APSDFLTK, and BLSROSYNC. The alarms clear after you configure
all the nodes in the BLSR. For definitions of these alarms, see the Cisco ONS 15454
Troubleshooting Guide.
Step 3 To change the BLSR 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. In network view, click the Provisioning > BLSR tabs.
b. Click the BLSR you want to modify and click Edit.
c. In the BLSR window, change any of the following:
• Ring Name—Assign a 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 BLSR.
• 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 BLSRs 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 BLSR 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-A326 Change a BLSR Node ID” task on page 20-16; otherwise, continue
with Step 5.
Step 5 In network view, verify the following:
• A green span line appears between all BLSR nodes.
• All E-W MISMATCH, RING MISMATCH, APSCIMP, DFLTK, BLSROSYNC, and Node ID
Mismatch alarms are cleared.
Note For definitions of these alarms, see the Cisco ONS 15454 Troubleshooting Guide.
Stop. You have completed this procedure.
