Changes to the Release Notes

This section documents supplemental changes that have been added to the Release Notes for Cisco ONS 15600 Release 1.4 since the production of the Cisco ONS 15600 System Software CD for Release 1.4.

No changes have been added to the release notes for Release 1.4.

Caveats

Review the notes listed below before deploying the ONS 15600 SDH. Caveats with DDTS tracking numbers are known system limitations that are scheduled to be addressed in a subsequent release. Caveats without DDTS tracking numbers are provided to point out procedural or situational considerations when deploying the product.

Maintenance and Administration


Caution VxWorks is intended for qualified Cisco personnel only. Customer use of VxWorks is not recommended, nor is it supported by Cisco's Technical Assistance Center. Inappropriate use of VxWorks commands can have a negative and service affecting impact on your network. Please consult the troubleshooting guide for your release and platform for appropriate troubleshooting procedures. To exit without logging in, enter a Control-D (hold down the Control and D keys at the same time) at the Username prompt. To exit after logging in, type "logout" at the VxWorks shell prompt.


DDTS # CSCec82095

A DCC in CTC grays out and does not come back if the DCC between two interconnected rings goes down (or is deleted) on one end. For this to occur, the login node and topology node must not be the same node. Also, the login node must lose visibility to the topology node when the DCC goes down. If the issue does occur, restart the active CTC session, or ensure that both sides of the

DCC termination have been deleted. Either action will update the CTC session OSPF information, allowing CTC to choose another topology host that is accessible. This issue is under investigation.

DDTS # CSCed29830

Circuit creation via CTC using auto-range incorrectly puts up circuits from the source node to the source node if bandwidth runs and is unavailable on the connecting DCC spans during the auto-ranged circuit creation. To avoid this issue, create the circuits individually instead of ranging the circuits if you have insufficient bandwidth on the links between the nodes. This issue will be resolved in a future release.

DDTS # CSCuk47105

A HELLO alarm is raised when a port is put OOS, because the DCC link is taken down (hence OSPF hello failure, when the port is OOS). The HELLO alarm will be present on a port even though the port is OOS and most alarms are masked for OOS ports. This issue will be resolved in a future release.

Line Cards

DDTS # CSCuk47837

On an STM 64 card the far-end MS-SES and far-end MS-UAS counters are not incremented. As a consequence the related threshold crossing alerts are never raised. The far-end MS-SES and far-end MS-UAS counters work correctly on MS-RDI defects. This is a hardware limitation.

MS-SPRing

DDTS # CSCec72283

If you remove the MS-SPRing provisioning at the NE level on an ONS 15600 SDH node while the fiber remains connected, the adjacent ONS 15454 nodes raise an APS CHANNEL FAILURE alarm. This issue is under investigation.

DDTS # CSCed20559

Rarely, if, using TL1, you issue an EXERCISE-RING on the east span of a two-fiber MS-SPRing and then immediately issue an EXERCISE-RING on the west span of the same two-fiber MS-SPRing, one of the requests might become stuck. If this occurs, wait 10 seconds and then issue another EXERCISE-RING on the east span. This issue will be resolved in a future release.

Interoperability

DDTS # CSCed42362

When the ONS 15600 interoperates with an NE that does not transmit bidirectional mode information in bits 6-8 of the K2 byte, for 1+1 APS bidirectional mode operation, the following APS defect alarms are not declared in SDH mode:

FEPRLF

APSM

APSCM

APSB

This issue will be resolved in a future release.

SNCP

DDTS # CSCed47156

When you manually create an open-ended SNCP circuit (two sources and one drop), only spans originating from the primary source are selectable. CTC does not allow you to select spans originating from the secondary source. Since the route is incomplete, manual creation of an open-ended SNCP circuit always fails. To work around this, when creating an open-ended SNCP circuit, select both Route Automatically and Review Routes before creation options in the "Circuit Routing Preferences" pane, then edit the spans in the "Route Review and Edit" pane. This issue will be resolved in a future release.

DDTS # CSCed39435

A manual switch request remains in place even after the path switches due to failure. The switch state should become APS_CLEAR, but remains MANUAL. This issue will be resolved in a future release.

Resolved Caveats for Release 1.4

Since Release 1.4 is the first release of the ONS 15600 SDH platform, there are no outstanding caveats resolved in Release 1.4.

New Features and Functionality

This section highlights new features and functionality for Release 1.4. Since this is the first release of the ONS 15600 SDH platform, there are no new features or functionality to compare to a previous release. For an overview of all features of the 15600 SDH, consult the user documentation.
