Release Notes for Cisco ONS 15310-CL
Release 6.2
Note
The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.
August 2007

Changes to the Release Notes
This section documents supplemental changes that have been added to the Release Notes for Cisco ONS 15310-CL Release 6.2 since the production of the Cisco ONS 15310-CL System Software CD for Release 6.2.
No changes have been added to the release notes for Release 6.2.
Caveats
Review the notes listed below before deploying the ONS 15310-CL. 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
CSCeh84908
A CTC client session can disconnect from an ONS node during simultaneous deletion of large numbers of VT level circuits (3000+). Connectivity to the node will recover without any user action. If the condition persists, restart the CTC session to reconnect. This issue is under investigation.
Data I/O Cards
CSCsb40206
In Asymmetric configuration, with autonegotiation enabled and flow control selected, an ML-series card might fail to synchronize with, or to recognize the asymmetric flow control. This issue is under investigation.
Path Protection Functionality
CSCee53579
Traffic hits can occur in an unprotected to path protected topology upgrade in unidirectional routing. If you create an unprotected circuit, then upgrade the unprotected circuit to a path protected circuit using Unprotected to path protection wizard, selecting unidirectional routing in the wizard, the circuit will be upgraded to a path protected circuit. However, during the conversion, traffic hits on the order of 300 ms should be expected. This issue will not be resolved.
Bridge and Roll
CSCei37364
When a rollTo leg is not receiving a good signal, and because of this the rollPending alarm is not cleared, there is no alarm indicating the reason that the RollPending alarm fails to clear. This issue is resolved in Release 7.0.
TL1
Note
Resolved Caveats for Release 6.2
The following items are resolved in Release 6.2.
Maintenance and Administration
CSCsd67191
Rarely, in a large network with many host routes the Proxy ARP server might run out of ring buffer storage, resulting in a subsequent failure of the driver to receive new packets. This can lead to DCC failure and loss of all connections. This issue is resolved in Releases 6.2 and 8.
CSCeg81602
A 100 second outage on DS1 traffic that is physically looped back, and in IS-AINS state, can occur during a span switch. With a loopback on the DS1 traffic a span switch will induce errors that raise a signal degrade (SD) on the DS1. The system then injects AIS due to the SD to keep from transitioning to IS from IS-AINS. To prevent this issue avoid using a physical loopback. This issue is resolved Release 6.0.
Data I/O Cards
CSCeh26707
Loss of Ethernet signal on one of the front ports takes longer than expected to be propagated to the remote port. Link integrity operates slower than expected for Ethernet failures (though it works as expected for SONET failures). To see this, any condition that causes an Ethernet loss of signal (removal of a front port Ethernet cable, for example) will invoke the Ethernet integrity function. This issue is resolved in Release 6.0.
CSCeh28342
On ML-series in the ONS 15310-CL, when policing is enabled, the configured policed rate is not forwarded. This can occur when policing at a rate lower than 1 Mbps. The workaround is to set the policed rate higher than 1 Mbps, or to raise the configured policed rate until the desired rate is forwarded. This issue is resolved in Release 6.0.
Path Protection Functionality
CSCec15064
A Path Protected/SNCP circuit with a defect signal present (for example, AIS-P or AIS-V) on the protect path will produce RDI-P or RDI-V upstream of the detection point, but these signals will not be detected or indicated. This issue is resolved in Release 6.0.
TL1 Functionality
CSCsb69386
If a TL1 tunnel is open on an ONS 153xx NE, sometimes when the NE reboots the nodes behind the tunnel will become permanently grayed out. This issue can occur when the tunnel far end is either rebooting or is already servicing other TL1 tunnels with several NEs behind the tunnel. To work around this issue, restart CTC at a later time, when the far end NE has less active TL1 tunnels. This issue is resolved in Release 6.2.
New Features and Functionality
This section highlights new features and functionality for Release 6.2. For complete documentation of each of the features of the ONS 15310-CL, consult the user documentation.

Note
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447For a complete list of Cisco TAC contacts, go to this URL:

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
