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.

Important Notes

  • After you run the show tech ofa command, the system prints the easy_debug_ltrace syslog message on the console. However, there is no functional impact on the router.

  • The total number of bridge-domains (2*BDs) and GRE tunnels put together should not exceed 1518.

    Here the number 1518 represents the multi-dimensional scale value.

  • The maximum number of Bridge-Domains that are supported in Release 6.5.3 is 250. However, the show l2vpn capability command displays the maximum number of BD supported as 750, which will be available in a future release.

  • The offline diagnostics functionality is not supported in NCS 540 platform. Therefore, the hw-module service offline location command will not work. However, you can use the (sysadmin)# hw-module shutdown location command to bring down the LC.

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.
