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 since the production of the Cisco ONS 15305 System Software CD for Release 1.1.
No changes have been added to the release notes for Release 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
•
•
•
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.
CDB Restore
Restore CDB does not complete successfully when the CDB backup is taken on a device running R1.0 the CDB contains "DccChannelMode" settings.
Workaround: When running R1.1 ICS03, first undo and then redo "DccChannelMode" settings and then take a new backup. 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" 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 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.
Resolved Caveats for Release 1.1
The following caveats were resolved in Release 1.1.
DDTS # CSCea34421
Multicast BPDU packets are mistakenly forwarded when spanning tree is disabled. This issue is resolved in Release 1.1.
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 is resolved in Release 1.1.
DDTS # CSCec87598
DCC-R/M disconnect/reconnect on MSP-create. This issue is resolved in Release 1.1.
DDTS # CSCed14104 and CSCed14314 and CSCed15692
Fatal error when trying to set speed 1000 MB on a GE port . This issue is resolved in Release 1.1.
