Release Notes for Cisco ONS 15600 Release 8.0
OL-10906-01
Caveats
Optical IO Cards
CSCse08282
When the Active XC is removed, the traffic from the line card might be lost. If the line card is an ASAP
card, the lack of traffic will cause a low transition signal density to enter the ASAP line card ASIC on
the backplane egress interface. The downstream FPGA on the ASAP 1PIO daughter card will begin
detecting B1 errors. These B1 errors will cause unexpected path protection switches. These errors will
also be reported as equipment failures.
To avoid this issue ensure that the Active XC is in OOS-MT state before removing it. If this issue does
occur, reset the 1PIO ASAP daughter card to clear the errored state. Resetting the ASAP carrier card will
also clear the errored state. This issue will be resolved in a future release.
CSCsc51518
In ASAP card view, the PIM graphic might not update with the correct color after an alarm is cleared.
This can occur anytime there is an alarm raised against the PIM or any of its subcomponents (PPM or
port). To recover from this state, you must either click the Synchronize button, or change to node view
and then back to card view. This issue will be resolved in a future release.
CSCef20813
No graphical representations of LEDs for ASAP ports are displayed in the CTC card view. SD and SF
LED representations are also absent from the CTC node view for some legacy OCn cards. There are no
plans to resolve this issue.
BLSR Functionality
CSCsd62731
When you create a circuit in IS,AINS state while a BLSR is in the switch state the circuit will not
transition from IS/AINS to IS. To avoid this ensure that the BLSR is in a stable state before creating a
circuit. This issue will be resolved in a future release.
CSCeh49665
Connections might still exist after circuit deletions on BLSR DRI rings for which the primary node is
isolated. For BLSR DRI rings with several types of DRI circuits, if you isolate the primary node by
deleting the database, reseat the I/O cards, then delete all BLSR DRI circuits, the SSXCs still show
connections. To avoid this issue, do not delete or create BLSR DRI circuits when a node on the BLSR
DRI ring is isolated. This issue will not be resolved.
