The Cisco Network Convergence System 540 Routers (NCS 540) complements Cisco’s offerings for IP RAN solutions for the GSM, UMTS, LTE, and CDMA. Cisco NCS 540 Series routers are designed with I-Temp grade devices.

The Cisco NCS 540 Series routers are designed for cost-effective delivery of these next-generation services. These routers are temperature-hardened, high-throughput, small form factor, low-power-consumption devices suitable for both outdoor and indoor deployments. They combine a comprehensive and scalable feature set of Layer 2 VPN (L2VPN) and Layer 3 VPN (L3VPN) services and a rich set of mobile features for a cost-optimized converged access platform. Capabilities such as advanced packet classification, segment routing, ultrawide ECMP, programmable network management, and telemetry are added to the robust and mature features already present in Cisco IOS XR Software.

This release notes describe the features provided in the Cisco IOS XR Software Release. See the Features Introduced in Cisco IOS XR Software Release 6.5.3 section in this document for information on new software features.

The bug IDs are sorted alphanumerically.


Note
The Caveats section includes the bug ID and a short description of the bug. For details on the symptoms, conditions, and workaround for a specific caveat you must use the Bug Search Tool.

Caveats Specific to the NCS 540 Routers

Bug ID

Headline

CSCvn15539

Memory alarms are observed when restart SMU is added and activated

CSCvi36859

Operational Failures are not made available to "Show configurations warnings" CLI

Upgrading Cisco IOS XR Software

Cisco IOS XR Software is installed and activated from modular packages, allowing specific features or software patches to be installed, upgraded, or downgraded without affecting unrelated processes. Software packages can be upgraded or downgraded on all supported card types, or on a single card (node).

The upgrade document is available along with the software images.

Production Software Maintenance Updates (SMUs)

A production SMU is a SMU that is formally requested, developed, tested, and released. Production SMUs are intended for use in a live network environment and are formally supported by the Cisco TAC and the relevant development teams. Software bugs identified through software recommendations or Bug Search Tools are not a basis for production SMU requests.

For information on production SMU types, refer the Production SMU Types section of the IOS XR Software Maintenance Updates (SMUs) guide.
