System Setup and Software Installation |
|
|
Install Owner and Partner RPMs Using IOS XR Install Infrastructure |
You can now use the existing IOS XR install infrastructure to install your proprietary Owner and Partner RPMs. This enhancement streamlines the process of integrating third-party software seamlessly into the IOS XR environment, including bundling the owner and partner RPMs into a GISO. In previous releases, you could only install Owner and Partner applications using the Application Manager interface. This feature introduces the keyword skip-implicit-owner-packages-checks in the following install commands:
|
|
Routing |
|
|
Introduced in this release on: ; NCS 5700 fixed port routers You can save IP addresses and resources, prevent the use of multiple node SIDs for labels associated with loopback interfaces, and save time configuring multiple loopback interfaces for an Area Border Router (ABR) in a network. These improvements are possible as you can now configure a single loopback interface for multiple areas. With this feature, an ABR can use a single loopback interface for all areas it connects to, eliminating the need for separate loopback interfaces for each area. Previously, each loopback interface was linked to only one area. The feature introduces these changes: CLI: The multi-area-interface command is extended to support loopback interfaces. |
|
| Introduced in this release on:NCS 5700 fixed port routers This feature enables prompt alerts for out-of-resource (OOR) conditions in IS-IS processes that could otherwise cause network instability and disruption due to memory leaks and excessive link-state packets (LSPs). That, in addition, they can disable the overload bit status flag that's included in the router's LSP to prevent setting of the overload-bit, but it's not recommended without Cisco consultation Previously, during OOR conditions, IS-IS processes restarted themselves, but the OOR conditions could persist. This ability to protect IS-IS processes in OOR conditions is enabled by default and you can't disable it. The feature introduces these changes: CLI:

|
|
Introduced in this release on: NCS 5700 fixed port routers This feature introduces support for NCS 5500 routers as a Seamless BFD (S-BFD) reflector. Seamless BFD simplifies the negotiation and state establishment aspects of BFD by predetermining session discriminators and maintaining session state only at the headend. This approach ensures quicker connectivity tests and reduces complexity in session establishment. Previously, support for Seamless BFD reflector was not available. The feature introduces these changes: CLI: This feature introduces the sbfd command. |
|
|
Segment Routing |
|
|
Data Plane Validation for SR-MPLS IPv6-based Controller Instantiated LSPs |
Introduced in this release on: NCS 5700 fixed port routers You can now verify the network configuration and paths and policies set up, without interrupting or potentially disrupting live network traffic, for SR-MPLS (Segment Routing over Multiprotocol Label Switching) IPv6-based Label Switched Paths (LSPs). With this feature, you can validate controller instantiated LSPs programmed directly into the forwarding hardware. Previously, SR data plane validation was possible over IPv4-based LSPs. The feature introduces these changes: CLI: The dataplane-only keyword is introduced in the traceroute sr-mpls and ping sr-mpls commands. YANG Data Models:
See (GitHub, Yang Data Models Navigator) |
|
Introduced in this release on: NCS 5700 fixed port routers You can now improve the user experience, understand the features and functionalities supported by neighboring routers, reduce operational work hours and human errors by gaining better visibility into the routing capabilities of directly connected neighboring routers in an OSPF network. These improvements are now possible when you enable Segment Routing on a neighboring connected router. Previously, there was no straightforward method to display the segment routing and other capabilities of neighboring routers in an OSPF network. The feature introduces these changes: CLI:

|
|
MPLS OAM support for SR-TE Policies using MPLS IPv6-based LSPs |
Introduced in this release on: NCS 5700 fixed port routers You can now verify the network configuration and paths and SR-TE policies set up, without interrupting or potentially disrupting live network traffic, for SR-MPLS (Segment Routing over Multiprotocol Label Switching) IPv6-based Label Switched Paths (LSPs). Previously, MPLS OAM support was only for IPv4-based LSPs. The feature introduces these changes: CLI: The traceroute sr-mpls and ping sr-mpls commands are extended to support IPv6 nexthop addresses. YANG Data Models:
See (GitHub, Yang Data Models Navigator) |
|
Introduced in this release on: NCS 5700 fixed port routers This feature adds support for user-defined generic metric as a metric type for IS-IS Flexible Algorithm. You can now have more control over traffic flows using user-defined generic metrics. You can define a family of user-defined generic metrics that can advertise different types of administrative metrics such as jitter, reliability, and fiscal cost depending on the traffic class for Flexible Algorithms. You can selectively define and assign semantics of these metrics as per the network requirement. The feature introduces the following changes: CLI:
YANG Data Models:
|
|
|
BGP |
|
|
Introduced in this release on: NCS 5700 fixed port routers You can now configure a maximum of 96 BGP additional paths instead of 32, which enhances network resiliency, and provides an improved load balancing capability. This feature introduces these changes: CLI:

|
Interface and Hardware Component |
|
|
Introduced in this release on: NCS 5700 fixed port routers With the carrier-delay timer functionality, the Ethernet interface state remains stable for the configured delay duration, even if the hardware link state fluctuates. This prevents interface flapping and improves network reliability. If you haven't configured the timer, the default carrier delay automatically delays the hardware link-up notifications by 200 ms. This time delay ensures that a stable hardware link state is established. If you want to change the delay of the interface state change notification, you can use the carrier-delay command to set a different value. The feature introduces these changes: CLI:
|
|
|
IP Addresses and Services |
|
|
Introduced in this release on: NCS 5700 fixed port routers You can now convert an entire TCP dump of packet traces in binary files into readable formats such as text or cap, which makes it easier to analyze them for troubleshooting using third-party or open-source tools. This feature saves time and effort by preventing the need to examine each packet for failure. This feature introduces the tcp dump-file convert command. |
|
|
L2VPN and Ethernet Services |
|
|
Layer 2 Fast Reroute on Cisco NCS 5700 series routers and line cards |
Introduced in this release on Cisco NCS 5700 fixed port routers Layer 2 Fast Reroute is now supported on the Cisco NCS 5700 series routers and line cards. |
|
L3VPN |
|
|
Introduced in this release on Cisco NCS 5700 fixed port routers Generic Routing Encapsulation (GRE) allows you to configure point-to-point and multiple traffic types connections to send the various types of network traffic. GRE supports L3VPN by encapsulating various network layer protocols, allowing IPv4 and IPv6 protocols to transport within the same GRE tunnel. |
|
|
You can now verify that MPLS labels are correctly programmed in the control plane (or software) and the data plane (hardware forwarding tables) using the show mpls forwarding labels command. Previously the command only showed the MPLS label information for software, additional steps were required to verify the label status in the hardware, by checking in the SDK. |
|
|
Modular QoS |
|
|
Introduced in this release on: NCS 5700 fixed port routers When a PE device transports IP traffic over a VXLAN tunnel that originates on the device, it automatically sets the DSCP value in the VXLAN outer IP header to 0 (CS0). |
|
|
Netflow |
|
| Introduced in this release on: NCS 5700 fixed port routers You now get a comprehensive view of your 5G network's performance and gain detailed insights into slice utilization, deployed QoS policies, and their impact on traffic. This includes verifying deployed QoS policies, assessing 5G slice mechanisms, and tracking GTP-U endpoints for specific applications. This feature specifically applies to 5G network slicing when the GTP User Plane carries data within the core network and to the radio access network. This is achieved by exporting GTP-U related Information Elements using Netflow and IPFIX records to collectors for analysis. This feature introduces these changes: CLI:
|
|
|
System Management |
|
|
Introduced in this release on:NCS 5700 fixed port routers This feature permits the flexible selection of timing sources by filtering out Foreign Master (FM) clocks that exhibit unstable timing. This filtering causes the secondary clocks to produce a signal deemed Packet Timing Signal Fail (PTSF)-unusable, from consideration within the Best Master Clock Algorithm (BMCA). The system continuously monitors these clocks for timing stabilization, and upon detecting enhanced stability, it may reevaluate and possibly reintegrate them as suitable time sources. This feature introduces these changes: CLI:
YANG Data Models: The following data models are enhanced:
|
|
|
PTP Phase Difference Threshold Between Passive and Secondary Ports |
Introduced in this release on:NCS 5700 fixed port routers Passive ports can now be included in the Delay Request-Response Mechanism (DRRM), which allows for the monitoring of PTP phase differences between a passive port and a secondary port. If these PTP phase differences surpass a predefined limit, system logs are triggered. This feature enables you to detect potential errors such as fiber asymmetry or a clock failure in the PTP network. This feature introduces these changes: CLI:
YANG Data Models: The following data models are enhanced:
|
|
System Security |
|
|
Layer 2 Untagged Sub-interface configuration in IEEE 802.1X Port-based Authentication |
Introduced in this release on: NCS 5700 fixed port routers This feature enhances network security by extending the 802.1X port-based authentication to Layer 2 untagged sub-interfaces. It ensures that data transmission is only possible from authenticated devices, including those on interfaces without VLAN tags. Consequently, this reinforces access control policies across all devices attempting to connect to the network. |
|
System Monitoring |
|
|
Introduced in this release on: NCS 5700 fixed port routers. We help you save debugging time to locate packet drops by automatically detecting nonzero traffic drops from the commands running in the background and giving you the exact location of the packet drop. In earlier releases, you used multiple show commands with their respective locations to detect packet drops. This feature introduces the show drops all command. |
|

Important Notes
-
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 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.
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
To determine the transceivers that Cisco hardware device supports, refer to the Transceiver Module Group (TMG) Compatibility Matrix tool.
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).
Before starting the software upgrade, use the show install health command in the admin mode. This command validates if the statuses of all relevant parameters of the system are ready for the software upgrade without interrupting the system.
Note |
You can ignore these messages and proceed with the installation operation.

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.
