Caveats
CSCsm19928 —AS-MT condition not persistent against subtended shelf TCC software reset
An AS-MT alarm on the transponder (TXP) card in a subtended shelf of a multishelf configuration is
cleared when a soft reset of the TCC is performed. The workaround is to change the port status to
IS-AINS and OOS-MT. This issue will be resolved in a future release.

CSCsu40460—External remote alarm relay is not set correctly
The External Alarm Relay (ERA) (A1/B1 VIS/AUD on the backplane) on a node created on the Cisco
ONS 15454 platform indicates incorrectly set remote alarms when remote nodes are raised or alarms are
cleared. This issue occurs under the following conditions:
ONS 15454 platform indicates incorrectly set remote alarms when remote nodes are raised or alarms are
cleared. This issue occurs under the following conditions:
1.
The node is stable with no MN/MJ/CR alarms on the entire network on a Cisco ONS 15454 platform.
2.
Another node on the network raises an MN/MJ/CR alarm, but it does not update the REM ALARM
VIS/AUD contact pins on the backplane.
VIS/AUD contact pins on the backplane.
3.
The issue occurs when the remote nodes clear their alarms also. (This issue has been observed since
Release 7.0).
Release 7.0).
The workaround is to create and clear an alarm or modify the severity of the already raised alarm (if
raised) on the node using the alarm profile.

Roll-pend(NA) and UNEQ-P(CR) alarms move to the Conditions pane when a soft reset is performed on
an active TCC during the manual mode of a circuit roll. No workaround is available for this issue. This
issue will be resolved in a future release.

BLSR Functionality
This section documents caveats for bidirectional line switched ring (BLSR) in Release 8.6.
CSCdv53427— Protection vulnerabilities in two-ring, two-fiber MS-SP ring configuration
In a two-ring, two-fiber BLSR configuration (or in a two-ring BLSR configuration with one two-fiber
and one four-fiber ring) it is possible to provision a circuit that begins on one ring, crosses to a second
ring, and returns to the original ring. Such a circuit can have protection vulnerabilities if one of the
common nodes is isolated, or if a ring is segmented in such a way that two non-contiguous segments of
the circuit on the same ring are both broken.
