Release Notes for Cisco ONS 15310-CL
Release 7.2
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.

Changes to the Release Notes
This section documents supplemental changes that have been added to the Release Notes for Cisco ONS 15310-CL Release 7.2 since the production of the Cisco ONS 15310-CL System Software CD for Release 7.2.
The following changes have been added to the release notes for Release 7.2.
Changes to Caveats
The following caveat has been added.
Caveats
Review the notes listed below before deploying the ONS 15310-CL. Caveats with tracking numbers are known system limitations that are scheduled to be addressed in a subsequent release. Caveats without tracking numbers are provided to point out procedural or situational considerations when deploying the product.
Maintenance and Administration
Caution
CSCse96077
In Release 7.2, when either you remove and then reinsert an I/O card, or a small burst of defects occurs for a very short period (less than 1 sec), false TCAs can be triggered that indicate line or traffic problems on an I/O port. Once triggered, the TCAs will be raised every 15 mins, after the 15 min pm report. There are no alarms for the associated ports. Traffic is not affected.
The cards affected are:
ONS 15454 DS1, DS1_E1_56, DS3 (including DS3, DS3N, DS3E, DS3NE), DS3_EC1, DS3XM, DWDM, E1, E1_42, OC3-8, OC12-4, MRC-12, OC192XFP; and ONS 15310-CL and ONS 15310-MA IO ports.
There are two workarounds:
1. Place the affected ports in OOS-DSBLD and then back to IS. This clears the problem for the specific port on the card, but the traffic will be down during the period of OOS-DSBLD.
2. Soft reset the card with problem ports. This clears the problem on all ports on the card. Soft reset might cause a protection switch if any port on that card or the card itself is in a protection group.
You can switch all protected ports away from the card that is to be soft-reset. In this case you can do manual switches away from the ports on that card, or in the case of an equipment switch, away from the equipment to be reset.
You can also perform a soft reset without any pre-action. This might result in protection switches of all active protected ports on that card. In the case of an equipment protection group resetting, the active equipment might incur a protection switch. The switch time will not exceed 60 ms.
For unprotected ports or card equipment, traffic will not be affected.
This issue will be resolved in a future release.
CSCsd52120
Disabling a member circuit other than the first member of a VCAT VCG, does not bring the traffic down. This issue will be resolved in Release 8.0.
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.
Alarms
CSCse85355
The NE should report alarms or conditions on ingress port not on any internal ports. Alarm detected at the internal ports (TERM) side will be ingress map to the MON side. So the NE raises the STS-MON/VT-MON and STS-TERM/VT-TERM alarms or conditions on the STS-MON/VT-MON ports, irrespective of the actual detection port (MON or TERM). If the user wants the customized severity to be reflected for a specifc STS/VT alarms, the alarm profile entities of both STS-MON and STS-TERM, if available, should be changed to the same severity.

Path Protection Functionality
CSCee53579
Traffic hits can occur in an unprotected to path protection topology upgrade in unidirectional routing. If you create an unprotected circuit, then upgrade the unprotected circuit to a path protection circuit using Unprotected to path protection wizard, selecting unidirectional routing in the wizard, the circuit will be upgraded to a path protection circuit. However, during the conversion, traffic hits on the order of 300 ms should be expected. This issue will not be resolved.

Note
Resolved Caveats for Release 7.2
The following items are resolved in Release 7.2.
There are no new resolved items in Release 7.2.
Common Control Cards
CSCsf13376
CRC threshold configuration and detection feature is broken for release 7.2. Excessive CRC errors does not cause CRC trigger action to take effect in this release 7.2. No workaround available. This issue is resolved in Release 8.0.
New Features and Functionality
This section highlights new features and functionality for Release 7.2. For complete documentation of each of the features of the ONS 15310-CL, consult the user documentation.
New Software Features and Functionality
Network Circuit Automatic Routing Overridable NE Default
The Network Circuit Automatic Routing Overridable NE default makes it possible to set by default whether or not a user creating circuits can change (override) the automatic circuit routing setting (also provisionable as a default).
The new NE default supporting this feature is:
CTC.circuits.RouteAutomaticallyDefaultOverridable
This default works in combination with the existing circuit routing default:
CTC.circuits.RouteAutomatically
The overridable option enables network administrators to manage how circuits are created on a network-wide basis. For example, if the Automatic Circuit Routing default is set to FALSE (the check box is unchecked by default), then setting the Network Circuit Automatic Routing Overridable default to FALSE ensures that manual circuit routing is enforced for all users creating circuits (the default is not overridable by the user). When the Network Circuit Automatic Routing Overridable default is set to TRUE (the factory configured setting) users can click in the Automatic Routing check box to change the automatic routing setting if they wish.
When the Route Automatically check box is not selectable during circuit creation, the following automatic routing sub-options will also be unavailable:
•
•
Like the Automatic Circuit Routing default, the Network Circuit Automatic Routing Overridable default applies to all nodes in the network. The Route Automatically check box is either overridable or not depending on how the default is set for the node you are logged into through CTC. To ensure correct behavior after setting the default, propagate the chosen default setting to all nodes through which users might log into the network to perform provisioning. For more information on NE defaults and their provisioning consult the user documentation.
