Cisco IOS XR Release 6.5.2 is a limited availability (LA) release. All Cisco IOS XR Release 6.5.2 features are available in Cisco IOS XR Release 6.5.3, which is a general availability (GA) release. For more information on IOS XR Release 6.5.3, see Release Notes for Cisco NCS 5500 Series Routers, Release 6.5.3

The Network Convergence System 5500 Series routers deliver a programmable, high-capacity and modular answer for Core, Peering, and WAN Transport deployments. Running the latest version of Cisco IOS XR Software, the 5500 Series supports segment routing, advanced forwarding feature sets, and programmable network management.

This series of routers deliver:

  • High-Performance, High-Density 100 Gb centric deployments

  • Option for redundant route processors, fabric cards, power modules and system controllers

  • Extreme focus on optimized power consumption in watts/Gbps

  • An infrastructure for hosting applications

  • Programmability with YANG model based APIs

The latest release of Cisco IOS XR operating system opens up the architecture of Cisco IOS XR using a 64-bit Linux-based operating system to deliver greater agility, automation and simplicity, while reducing cost of operating the networks.

Software Features Introduced in this Release

Cisco IOS XR Release 6.5.2 contains all features released in Cisco IOS XR Release 6.5.1. Release 6.5.2 and Release 6.5.1 are limited availability (LA) releases. For more information on IOS XR Release 6.5.1 features, see Release Notes for Cisco NCS 5500 Series Routers, Release 6.5.1

  • G.8273.2

  • G.8275.1

  • G.8275.2

For more information, see Configuring Precision Time Protocol chapter of the System Management Configuration Guide for Cisco NCS 5500 Series Routers.

MPP for Third-Party Applications

This release introduces the following changes for MPP for Third-Party Applications feature:
  • Introduction of sub-mode protection under tpa sub-mode

  • Only tcp and udp protocol can be specified as parameters for the allow protocol command

  • The control-plane and management-plane configuration is now moved to protection sub-mode under tpa.

For more information about MPP, see the System Management Configuration Guide for Cisco NCS 5500 Series Routers.

SR-TE On-Demand Next Hops for 6PE and 6VPE

On Demand Next hop (ODN) leverages upon dynamic SR-TE capabilities and adds the path computation (PCE) capability to find and download the end to end path based on the requirements. Using the SR-TE On-Demand Next Hops for 6PE and 6VPE feature, you can trigger automatic SR-TE tunnels to route traffic based on specific constraints (for example delay and bandwidth) for 6PE and 6VPE services.

New Hardware Introduced in this Release

Important Notes

  • MLD Snooping is not supported until Cisco IOS XR Release 6.5.3. The support will be available in future releases.

  • The SRLB (Segment Routing Local Block) inconsistency and allocation failure error is observed when a non-default values of SRLB and SRGB (Segment Routing Global Block) are configured and a commit-replace is followed by configuration re-application. This issue impacts data forwarding as the SR labels are not properly programmed.

    To prevent the issue, use the clear segment-routing local-block discrepancy all command to clear the label conflicts.

  • The offline diagnostics functionality is not supported in NCS 5500 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.

  • The warning message that the smart licensing evaluation period has expired is displayed on the console every hour. There is, however, no functionality impact on the device. To stop the repetitive messaging, register the device with the smart licensing server and load a new registration token.

    To register the device with the smart licensing server, follow the instructions provided in this link: Register and Activate Your Device.

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.
