Important Notes

Upgrade Issues

After upgrading to Cisco EPN Manager 4.1:

  • FTP and TPTP will be disabled by default.

  • Active threshold crossing alarms (TCA) for temperature will remain active and will not be cleared. Please clear these alarms manually.

  • Devices must be resynced in order to view ISIS links and ISIS LTPS.

  • LDP-enabled devices must be resynced in order to view LDP feature-related information.

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

Limitations on Carrier Ethernet Circuit Provisioning

  • Promotion of service using old probe name format will be supported and probes will get listed in user interface with appropriate standard OAM Profile name after promotion.

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

  • Till custom profiles names is supported, empty modification of brownfield services with different naming format will cause deleting of existing custom profile and adding of new profiles with provisioning supported name format.

  • Inventory models only loose and delay profiles which is associated to service. But, there can be profiles in device which is not associated to any service. Validation if limit of 100 profiles is reached in device is not handled before config is deployed.

  • Error will be thrown from device and deploy will get failed when user tries to create new SLA operation profile when EPNM tries to create 101th profile.

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, they must be upgraded. Wherever possible, the Cisco EPN Manager documentation highlights the potentially affected systems. Please contact your Cisco representative for support in this regard, if necessary.

Reconciliation Report Limitations

When provisioning a service, if you have not provided a value for any of the attributes, the provisioned value for those attributes will be displayed as “Missing” in the reconciliation report. The device may have default values for these attributes but Cisco EPN Manager does not have any values configured.

Limitations on ME 1200 Devices

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

Limitations on NCS 4200 Devices Running IOS-XE 16.8.1

The following functionality does not work on 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 NCS540 and NCS5500 devices

  • NCS540 device series does not support Fault-OAM, Wrap-Protection and BFD.
  • NCS5500 device series does 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

No Support for 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, 2006 and 2015 devices.

Data Center Device Lifecycle Support Only

Cisco EPN Manager provides foundation lifecycle support for UCS compute systems, CSR 1000v, and Nexus series devices but does not provide data center topology.

LINK_DOWN alarm on sub interfaces in Gig Port

LINK_DOWN alarms will not be generated when link is down on sub interfaces in Gig Port.
