• Resolved Bugs

• Get Information about Cisco EPN Manager Bugs

Cisco EPN Manager software is distributed with all the components necessary for its optimized and secure operation, including the Red Hat Linux operating system and the Oracle database. All security-related configurations, regression testing, performance, and scalability metrics are based on the set of components and configurations included in the original Cisco EPN Manager software distribution. Cisco provides periodic EPN Manager software updates that can also contain necessary updates to the packages installed on the operating system or to the database.

Note that if any of the following changes are made to the original distributed Cisco EPN Manager software, Cisco will no longer support the operating environment:

• Configuration changes to the software or operating system, or installation of other components that are not part of the original distribution.

• Direct installation and application of third-party software on the Red Hat Linux operating system embedded within Cisco EPN Manager.

• Application of updates or patches that are not provided by Cisco to individual Cisco EPN Manager components.

• Changes to the internal Cisco EPN Manager settings that are not documented as modifiable in the Cisco EPN Manager User and Administrator Guide on Cisco.com, as these changes may weaken security, disable functionality, or degrade scalability and performance.

Upgrade Issues

• FTP and TFTP are disabled by default.

• Active Threshold Crossing Alarms (TCA) for temperature remain active and are not cleared automatically. Clear these alarms manually.

• You must resync your devices to view ISIS links.

• You must resync LDP-enabled devices to view LDP feature-related information.

• You must recreate the TCAs for inbound/outbound errors and inbound/outbound discards in the Interface Health monitoring policy.

Limitations on Carrier Ethernet Circuit Provisioning

• Promotion of service using old probe name format is now supported. These probes are listed in the user interface with the appropriate standard OAM Profile name after promotion.

• Sample profile: profile PM2_3_8_CoS5_DM type cfm-delay-measurement.

• While custom profile names are supported in EPN Manager, modifying brownfield services with a different naming format deletes the existing custom profile and adds a new profile with a supported naming format.

• Inventory models do not correctly display the profiles that are not associated to a service.

• Validation limit for number of profiles is 100. If you create a new SLA operation profile after 100 existing profiles, the device generates an error and deployment fails.

TLS 1.2 Required for Secured Channel Communication for HTTPS and TLS

Only Transport Layer Security (TLS) 1.2 is supported for HTTPS and TLS related secured communication, for example, RADIUS EAP-TLS.

Support for TLS 1.0, TLS 1.1, and all versions of SSL has been disabled due to security vulnerabilities.

This means that all peer systems and clients that transact with Cisco EPN Manager using HTTPS/TLS must support TLS 1.2. If they do not support TLS 1.2, you must upgrade these systems. Wherever possible, the Cisco EPN Manager documentation highlights the potentially affected systems. Contact your Cisco representative for support in this regard, if necessary.

Reconciliation Report Limitations

If you have not provided a value for an attribute while provisioning a service, the provisioned value for that attribute is displayed as “Missing” in the reconciliation report. The device may have a default value for this attribute, but Cisco EPN Manager does configure this value.

Limitations on Cisco ME 1200 Devices

The Y.1564 performance test does not work if the source/destination is a Cisco ME 1200 device.

Limitations on Cisco NCS 4200 Devices Running IOS-XE 16.8.1

The following functionalities do not work on Cisco NCS 4200 devices running IOS-XE 16.8.1:

• Alarm profile

• Configuration of SONET LOP and CT3 LOP from the GUI

• Admin shut/no shut functionality on SONET/T1/T3 HOP/LOP

Limitations on Cisco NCS 540 and Cisco NCS 5500 devices

Cisco NCS 540 and Cisco NCS 5500 device series do not support Fault-OAM, Wrap-Protection, and BFD.

Use CLI Templates for Configuring PTP Commands

On ASR920 devices with software version 16.9.1, IEEE 1588-2008 BC/MC license is required to execute the 1588 PTP commands.

Configuration and Inventory Not Supported for PTP Templates

The behavior of modeling the configurations pushed through PTP templates may not work as expected because the model may not be in place for all the configurations pushed through PTP templates. Configuration/Inventory is not supported for these configurations.

Deprecation of Support for ONS 10.00.10, 10.01.00, 10.03.00

ONS 10.00.10, 10.01.00, 10.03.00 ONS 10.00.10, 10.01.00, and 10.03.00 are no longer supported on Cisco NCS 2002, Cisco NCS 2006, and Cisco NCS 2015 devices.

Data Center Device Lifecycle Support Only

Cisco EPN Manager provides sssential support for a few selected UCS compute systems, Nexus series devices, and the CSR 1000v devices.
