Release Notes for Cisco ONS 15600 Release 8.0
OL-10906-01
Caveats
CSCdz07098
If OSPF on LAN is enabled with an area ID that is the same as the area ID of any of the DCC Links,
CTC will not be able to discover any of the DCC Connected Nodes. To avoid this issue, set the OSPF on
LAN area ID to an area other than any of those already occupied by a DCC link. This is as designed.

Equipment alarms are always reported based on the activity of the particular card, without taking card
redundancy into consideration. Thus, an equipment alarm such as CTNEQPT-PB-0 may be raised
against a line card as CR(SA) even though the traffic is protected. This issue will not be resolved.

Choosing certain qualities of RES settings in the CTC Provisioning tab, Timing subtab, may trigger a
reference failure. Specifically, this can occur if you select the quality of RES level such that any of the
following are true.
• ST3 < RES < ST3E
• ST4 < RES < SMC
• RES < ST4
When you then input an actual reference signal lower than ST3E quality, the failure is triggered. This
issue will not be resolved.

ONS 15600 SDH is unreachable through CTC, during a system reset when performing an upgrade after
the activate step but before the accept step. A system soft reset is a controlled sequence of soft resetting
all the boards in the shelf. During the upgrade the introduction of this system reset causes
communication problems with both TSCs; thesystem does not know which TSC issupposed to be active.
There is a procedure for an upgrade where a shelf reset should not be done by the operator. There is no
way for an automatic shelf reset to occur. On any power-down, the system comes up on the old code
without any issues involved. A workaround is to avoid a system reset during upgrade process.
