Changes to the Release Notes

This section documents supplemental changes that have been added to the Release Notes for Cisco ONS 15305 Release 1.0 since the production of the Cisco ONS 15305 System Software CD for Release 1.0.

The following changes have been added to the release notes for Release 1.0.

Caveats Added

The following caveats have been added.

DDTS # CSCeb22543

DDTS # CSCea71600

Caveats

Review the notes listed below before deploying the ONS 15305. 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.

DDTS # CSCeb22543

On 8xSTM1 cards there may be packet losses for LAN traffic mapped on STM1, and "DXC inlet bit error alarm" conditionsmay be raised, when 8xSTM1 cards are exposed to extreme temperature cycles (-5 to 50°C with 2 hours dwell at each extreme temperature, and 1°C/min gradients). The packet losses and raised condition can occur on the 8STM1 card. This only occurs under temperature stress. The frequence with which the issue has been observed is an average of 10 packets lost, and less than 100 alarms recorded in a 12 hours cycle. No failures have been detected in nominal conditions.

DDTS # CSCea71600

When power cycling (power on/off at different termperatures) the 8xSTM1 card, the card may fail to recover operation after the power on/off, and may remain in an alarmed state without carrying traffic. In this case the card indicates "DXC inlet failure alarm." The card's LED will also be red. The card recovers normal operation after a software reset. This issue occurs approximately one out of every 20 power on/offs.

DDTS # CSCea34055

When a module with one or more Ethernet switches is hot-inserted in a free slot of the ONS 15305, some packet loss may occur for any IP traffic currently being forwarded by other modules already present in the ONS 15305. This issue will be resolved in a future release.

DDTS # CSCea34421

Multicast BPDU packets are mistakenly forwarded when spanning tree is disabled. This issue will be resolved in a future release.

DDTS # CSCeb19897

When multiple VC12 containers used by the same Ethernet circuit take different paths in an SDH network, the 6.5 ms tolerance to delay between the separately routed packets does not work properly and 25-30% of the traffic may be lost. This issue will be resolved in a future release.

DDTS # CSCea31245

If you send 100 MB from two ports to a single port (for example, to test flow control), 64 byte packets are lost. If you increase the size to 75 bytes, packets are no longer lost. This type of traffic is not, however, typical for a device in normal operation. This issue will be resolved in a future release.

DDTS # CSCea33042

Same priority and same packet size may yield different traffic flows. When four streams are set up and each has the same packet size (64 byte) going across a 100 MB STM-1 path to another ONS 15305, each of the streams can be off as much as 50%. This is not always the case, however. Sometimes the traffic can be equally distributed. Using random packet sizes, the distribution tends to be more equal. This type of traffic in not typical for a device in normal operation; however, the issue can occur in a lab test. This issue will be resolved in a future release.

DDTS # CSCea33354

If a mirrored port becomes congested and flow control is enabled, no pause packets are generated toward ports belonging to other modules. Flow control fails when ports used for mirroring become congested. If traffic to a mirrored port is sent from a LAN port situated in a different module from that of the mirrored port, pause packets are not received and mirrored packets are lost. Actual traffic flow is not disturbed by the mirrored port flow control problem, and the copy port traffic is handled correctly. This issue will be resolved in a future release.

Resolved Caveats for Release 1.0

Because Release 1.0 is a first release, there are no resolved caveats.

New Features and Functionality

This section highlights new features and functionality for Release 1.0. Because Release 1.0 is a first release, there are no new features or functionality. For an overview of features of the 15305, consult the Cisco ONS 15305 Installation and Operations Guide, Release 1.0.
