Changes to the Release Notes

This section documents supplemental changes that have been added to the Release Notes for Cisco ONS 15305 Release 1.1.1 since the production of the Cisco ONS 15305 System Software CD for Release 1.1.1.

No changes have been added to the release notes for Release 1.1.1.

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 # CSCea33196

Unfair distribution of intermodular traffic with flow control can occur. If traffic is sent from several ports in different modules and flow control is active, traffic throughput is less for ports belonging to same module as the congested.

Typical scenario:

Port 2 module 1, port 1 module 2 and port 1 module 3 send 100Mb traffic streams to port 1 module 1. All ports have flow control enabled. The result is that more traffic is sent from the ports in module 2 and 3 compared to what is sent from the port in module 1. No packet loss from any module occurs. This issue will be resolved in a future release.

DDTS # CSCea33337

Port priority is not strictly enforced when flow control is on. This can occur under the following

conditions.

The four input ports are set for 100 MB (64 bytes).

Port 1 priority is set for 6

Port 2 priority is set for 4

Port 3 priority is set for 0

Port 4 priority is set for 1

VLAN tagging is turned off for all of the FE ports while VLAN tagging is turned on for the STM1 trunk port. (This adds an additional 4 bytes to each stream.) Flow control is turned on for all the FE ports When all the ports are turned on, only Port 1 should have priority. Instead, traffic is received on both Ports 1 and 2 at almost 60/40% on each port (81,168 versus 60,876). This issue will be resolved in a future release.

DDTS # CSCeb22543

On 8xSTM1 cards there may be packet losses for LAN traffic mapped on STM1, and "DXC inlet bit error alarm" conditions may 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 8xSTM1 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 # 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.

DDTS # CSCee44527

GE-port does not handle traffic in FIBER mode when AUTONEG is ENABLED. The gigabit Ethernet port does not handle traffic when media type fiber is used and autonegotiation is enabled.

Workaround:

Set the administrative speed to 1000 MB and disable autonegotiation on the gigabit Ethernet port if fiber link is used.

DDTS # CSCee44539

SYSTEM-UP-TIME is incorrect . System- up- time should be able to store up- time up to approximately 497 days. Counters reset at approximately 40 days, causing the up time to display incorrectly. This issue is under ongoing investigation.

DDTS # CSCee44553

"Ping events"are incorrectly described. When using the "ping utility" from CiscoEdgeCraft, if the ping is not successful, abortTftp events are reported. Tftp events are not relevant in this context. This issue is under ongoing investigation.

DDTS # CSCee44556

A restart is triggered when receiving a specific frame (BOOTP). ONS 15305-s connected to a common HUB via MNGT-port reboot after having been in operation for some time. ROS is sensitive to specific frames (BOOTP) and this causes a software restart. This vulnerability applies for all IP-addressed ports (LAN/WAN/MNGT). This issue is under ongoing investigation.

Workaround:

Turn off BootP messaging from the router (in this specific case).

DDTS # CSCee44563

A GE-port reports incorrect media/connection-type.Under certain circumstances, the media type and connector type reported for a GE-port might be wrong if the GE-module is put in traffic while the cable is in and the peer is ready to bring the link up. The issue is not traffic-affecting, and the port's Operational Status is "up." Inconsistency might occur if the link comes up very fast, and after that the module is put in traffic. The inconsistency has been observed if autonegotiation is disabled and the media type is fiber (speed is set to 1000 MB). If the module is put in traffic while the fiber is plugged in and the peer is ready to bring the link up, the media type might be reported to be copper and the connector type to be RJ45 (instead of the correct values of fiber and fiberLC respectively). This issue is under ongoing investigation.

Workaround:

Provoke a link-down link-up transition (remove and reinsert the cable force wrong port-speed and reset back to the correct port-speed). When the link comes up again after having been down for a few seconds, the reported media/connection-type will be correct.

DDTS#CSCee27998

Mismatch between 'Running SW Revision' presented during start-up and the actual software in the equipment.

Workaround:

Verify the SW-ICS by means of either VT100 or CEC. For R1.1.1, the correct SW-ICS is ICS06.

This issue will be resolved in a future release.

Resolved Caveats for Release 1.1.1

The following caveats were resolved in Release 1.1.1

Restore CDB does not complete successfully when the CDB backup is taken on a device running R1.0 the CDB contains "DccChannelMode" settings.

Optical link on GE port does not come up if autonegotiation disabled and speed 1000

STM16 module - OOF/LOF when setup as VC-4-4C (new STM16 module-file)

Memory corruption (sDxcTu12Connections table in DXCT.c)

Too short GALNET reset
