Important Notes
Known Issues
Problem Statement 1: TL1 Profile creation requires mandatory SNMP parameters.
Description: While attempting to create a TL1 profile, users encountered an issue where the mandatory SNMP parameters were required. However, SNMP parameters are not mandatory for creating the TL1 profile.
Problem Statement 2: Unsuccessful saving of TL1 credentials in credential profile page.
Description: While creating a TL1 profile, TL1 credentials were not saved in the policy detail page. Despite the operation indicating success, the TL1 credentials were not being stored as intended.
Resolution:
To address these issues, a patch has been implemented to update the JS component on the customer setup. The patch can be applied by executing the install_baseui.sh script found under the /opt/CSCOlumos/updates/cepnm7.0-dpp1-buildXXX/epnm_7_0_updates/scripts/install_baseui.sh.
To apply the patch, follow these steps:
-
Establish a secure SSH connection to the server hosting the Cisco EPN Manager.
-
Navigate to the patch location by running the command: cd /opt/CSCOlumos/updates/.
-
Copy the install_baseui.sh script to the updates directory using: cp /opt/CSCOlumos/updates/cepnm7.0-dpp1-build156/epnm_7_0_updates/scripts/install_baseui.sh /opt/CSCOlumos/updates/.
Note
Replace cepnm7.0-dpp1-build156 with the appropriate build number, if necessary.
-
Make the install_baseui.sh script executable:
chmod 755 install_baseui.sh
-
Execute the install_baseui.sh script using the command:
This script applies the patch to the JS component.sh -x ./install_baseui.sh
-
Perform a hard refresh of your browser to ensure the changes take effect immediately. Restarting the browser is not necessary.
With these resolutions in place, TL1 profiles can now be created without being prompted for mandatory SNMP parameters, and TL1 credentials can be successfully saved within credential profiles.
Upgrade Issues
-
FTP and TPTP 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 IS-IS 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 Editing Alarm Notification Policies
If the upgrade conditions of existing categories are different from the condition of categories on 5.1, then the conditions post upgrade will not match. As a result, policy might not be created, or UI selection might not take place for the unmatched events. In this case, you should delete the upgraded policies and create a new one.
Limitations on NCS 4200 Devices Running IOS-XE 16.8.1
The following functionalities do 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 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 that are pushed through PTP templates may not work as expected because the model may not be in place for all the configurations that are 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, 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 a Gig Port.
