Network Convergence System 560 Series Routers
What's New in Cisco IOS XR Release 25.1.1
For more details on the Cisco IOS XR release model and associated support, see Software Lifecycle Support Statement - IOS XR.
Software Features Enhanced and Introduced
To learn about features introduced in other Cisco IOS XR releases, select the release from the Documentation Landing Page.
| Feature | Description |
|---|---|
|
Segment Routing |
|
|
The network administrators can now monitor and manage network performance, capacity planning, and traffic engineering by reviewing the policy counters (POL.CP.SL.INT.E) in SRv6-TE. The feature introduces these changes: CLI:
|
|
|
This feature introduces support for Static Segment Routing over IPv6 (SRv6) Pseudo-wires in the IOSXR platform. This enhancement aims to extend the existing Virtual Private Wire Service (VPWS) capabilities by incorporating SRv6, providing improved flexibility and scalability for service providers. |
|
|
L2VPN and Ethernet Services |
|
|
You can now manage and minimize Neighbor Discovery (ND) for IPv6 traffic on a network segment by configuring partial suppression mode. You can configure EVPN-IRB ARP and ND proxy full or partial suppression modes for these features:
|
|
|
You can now ensure faster convergence and uninterrupted service by redirecting the traffic using the EVPN pseudowire (PW) in an E-Line configuration when a dual-homing link fails. |
|
|
Interface and Hardware Component |
|
|
For statistics aggregation, you can now configure a distinct width for the first bin to adjust for large propagation delay. By using this feature, you can avoid wasting several bins that would be empty in some unavoidable situations such as delay due to speed of light limitations. The feature introduces these changes: CLI:

YANG Data Models Introduced and Enhanced
This release introduces or enhances the following data models. For detailed information about the supported and unsupported
sensor paths of all the data models, see the Github repository. To get a comprehensive list of the data models supported in a release, navigate to the Available-Content.md file
for the release in the Github repository. The unsupported sensor paths are documented as deviations. For example, openconfig-acl.yangprovides details about the supported sensor paths, whereas cisco-xr-openconfig-acl-deviations.yang provides the unsupported sensor paths for openconfig-acl.yang on Cisco IOS XR routers.
You can also view the data model definitions using the YANG Data Models Navigator tool. This GUI-based and easy-to-use tool helps you explore the nuances of the data model and view the dependencies between various containers in the model. You can view the list of models supported across Cisco IOS XR releases and platforms, locate a specific model, view the containers and their respective lists, leaves, and leaf lists presented visually in a tree structure.
To get started with using data models, see the Programmability Configuration Guide for Cisco NCS 560 Series Routers.
| Feature | Description |
|---|---|
|
Programmability |
|
|
Cisco-IOS-XR-infra-sla-cfg.yang |
This native yang data model is enhanced to support BinsMinDelay and MinDelayMicroseconds options under the existing YANG leaf: |
|
Cisco-IOS-XR-um-ethernet-sla-cfg.yang |
This unified data model is enhanced to support BinsMinDelay and MinDelayMicroseconds options under the existing YANG leaf: |
|
Cisco-IOS-XR-infra-sla-oper.yang |
The existing bin width leaf in the Cisco native data model reflects the configured minimum delay value. |
Hardware Introduced
 Note |
Before you install the Cisco router, you must prepare your site for the installation, for more details on site planning and environmental requirements, see Hardware Installation Guide. |

Optics |

Behavior Changes
-
From this release, the default order of authentication methods for SSH clients on Cisco IOS XR routers running Cisco IOS XR SSH is changed to: public-key, keyboard-interactive, and password.
Prior to this release, the default order was: public-key, password, and keyboard-interactive.
-
Prior to Cisco IOS XR Release 7.2.1, a segment of an explicit segment list can be configured as an IPv4 address (representing a Node or a Link) using the index indexaddress ipv4 address command.
Starting with Cisco IOS XR Release 7.2.1, an IPv4-based segment (representing a Node or a Link) can also be configured with the new index index mpls adjacencyaddress command. The configuration is stored in NVRAM in the same CLI format used to create it. There is no conversion from the old CLI to the new CLI.
Starting with Cisco IOS XR Release 7.9.1, the old CLI has been deprecated. Old configurations stored in NVRAM will be rejected at boot-up.
As a result, explicit segment lists with IPv4-based segments using the old CLI must be re-configured using the new CLI.
There are no CLI changes for segments configured as MPLS labels using the index index mpls label label command.
-
If you are on a release before Cisco IOS XR Release 7.4.1, you can configure SR-ODN with Flexible Algorithm constraints using the segment-routing traffic-eng on-demand color color dynamic sid-algorithm algorithm-number command.
Starting with Cisco IOS XR Release 7.4.1, you can also configure SR-ODN with Flexible Algorithm constraints using the new segment-routing traffic-eng on-demand color color constraints segments sid-algorithm algorithm-number command.
From Cisco IOS XR Release 7.9.1, the segment-routing traffic-eng on-demand color color dynamic sid-algorithm algorithm-number command is deprecated. Previous configurations stored in NVRAM will be rejected at boot-up. (Performing In-Service Software Upgrade (ISSU) to Cisco IOS XR Release 7.9.1 will also be rejected.)
Hence, for Cisco IOS XR Release 7.9.1, you must reconfigure all SR-ODN configurations with Flexible Algorithm constraints that use the on-demand dynamic sid-algorithm with the on-demand constraints command.
Restrictions and Limitations
-
Telemetry data collection may timeout due to CPU overload during route churn. In such scenarios, telemetry will resume when the CPU becomes available after the route churn is complete.
-
The standby RP may get into '
NOT READY' state intermittently due to some network churn, though the corresponding VM is up and running. But this is a transient state and shows that some data aren’t in sync between active and standby due to the network churn. After both active and standby are in sync with respect to all the parameters, then the standby RP comes into 'READY' state.
Caveats
There are no caveats in this release.

Important Notes
Licensing
Starting with Cisco IOS XR Release 24.1.1, Smart Licensing Using Policy (SLP) is the default Licensing model. When you upgrade to the Cisco IOS XR Release 24.1.1 release or later, the Smart Licensing Using Policy is enabled by default.
You can migrate your devices to Smart Licensing with Policy model, see Migrating from Smart Licensing to Smart Licensing Using Policy, Smart Licensing Using Policy on Cisco IOS XR Routers.
We recommend that you update to the latest version of SSM On-Prem or Cisco Smart Licensing Utility.
Note |
SSM On-Prem and CSSM both support SLP devices and SL devices. SLP devices and SL devices can coexist in a network. The Smart Licensing (SL) model is available in releases Cisco IOS XR Release 7.11.1 and earlier. |
Supported Transceiver Modules
For more information on the supported transceiver modules, see Transceiver Module Group (TMG) Compatibility Matrix. In the Begin your Search search box, enter the keyword NCS560 and click Enter.
Upgrading Cisco IOS XR Software
For software installation and upgrades, refer to the respective upgrade/downgrade docs .tar files based on your 560 router varaint.
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 for Cisco NCS 560 router is available along with the software image in NCS560_Upgrade_MOP_25.1.1.tar file.
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.
Cisco IOS XR Error messages
To view, search, compare, and download Cisco IOS XR Error Messages, refer to the Cisco IOS XR Error messages tool.
Cisco IOS XR MIBs
To determine the MIBs supported by platform and release, refer to the Cisco IOS XR MIBs tool.
