GUI - General

• EPNM should support UI for EVPN-VPWS service for Discovery, Provisioning , Assurance similar to other VPN services

• Enhancements to GUI accessibility for visually and motorically impaired users

• Enhancements to link rename capabilities to support longer link names.

• User selection for the columns (including width) in the links list page is retained

Device Configuration

• Sylsog Alarm Generation when a configuration template deployment fails

• Segment Routing configuration using Model-Based Configuration from UI

• Support to distinguish between Configuration Template and Troubleshooting Template

• Support configuration of TWAMP LITE probe using Model-Based Configuration from UI

Installation

Note	EPNM installation over KVM and OpenStack are marked “BETA” in release 4.0, providing limited functionality. The intention is to fully support these features in the next release.

• Support EPNM installation over KVM

• Support EPNM Installation over OpenStack (limited scenario)

• Support migration from Oracle to Open Source Java JDK

• Update embedded Linux to release 7.7

• Upgrade Oracle JRE library to latest release

Segment Routing

• ECMP support for SR Policy overlay

Circuit Emulation

• SDH/Sonet Terminology in EPNM needs to be updated

Circuits/VCs - General

• EPNM To support Provisioning, Discovery, Fault, Assurance, Performance for Segment Routing

• EPNM allowed provisioning of an OC12 circuit outside a tunnel. The circuit worked but bandwidth was not reserved and would have been best effort. EPNM does not provide a way to diagnose this

• EPNM allowed provisioning of an OC48 circuit inside a tunnel when that tunnel did not have sufficient bandwidth to transport it with no warning. EPNM does not provide a way to diagnose this

• EPNM- Generate a Sylsog Alarm when a service provisioning request FAIL

• Once a service has been provisioned, it should be possible to edit the service and update or change the Z point for CEM service

• Rollback template should be automatically invoked by EPNM when service rollback is performed in case of failure

CE Provisioning

• Added a new column ‘Sub policy’ to reflect if a policy is a sub-policy or not

Carrier Ethernet

• Ethernet SLA profile name to be properly managed to avoid the 100-profile limitation on XR

  • The naming convention used in XR devices, “PM<level>_<ProbeId>_<PWId>_CoS<level>_DM/LM” leads to the creation of multiple probe with different name but same configuration.

  • Limitation of 100 SLA probes in XR device is now handled by creating probes in the name format “PM<level>_ CoS<level>_ DM/LM”, which will be shared across services in a device.

  • 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 or services created before upgrade with different naming format will cause deleting of existing profile and adding of new profiles with provisioning supported name format.

  • Inventory models only loss 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.

Note	G8032 is not supported and has been deprecated starting EPNM release 4.0

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

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 Bidirectional tunnel functionality.

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

Limitations on IoT Devices Running IOS-XE 16.9.1

Following are the limitations on IoT devices running IOS-XE 16.9.1:

• RS422 and RS485 works on ports from 0 to 7 only.

• RS232 synchronous mode works on ports 8-13 only.

• If any one of the ports in 0, 1, 2 and 3 is configured with type TO or any other type, then all the four ports 0, 1, 2 and 3 will be automatically configured with the same type.

• If any one of the ports in 4 and 5 is configured with type TO or any other type, then the two ports 4 and 5 will be automatically configured with the same type.

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.

EIGRP and RIP Not Supported

As of Cisco EPN Manager 2.2.1, EIGRP and RIP inventory and configuration support has been discontinued.
