|
IP Addresses and Services |
|
|
Support for 255 IPv4 and 255 IPv6 VRRP sessions on Cisco NC57 line cards |
VRRP provides failover redundancy at the first hop by grouping individual routers to form a virtual router. In this release, by default, Cisco NC57 line cards support 255 IPv4 and 255 IPv6 VRRP groups in the native mode. This feature decreases the chances of packet drops. From Release 7.0.2, this support was available only in the compatibility mode. |
|
L2VPN and Ethernet Services |
|
|
This feature is now supported on Cisco NCS 5700 series fixed port routers and the Cisco NCS 5500 series routers that have the Cisco NC57 line cards installed and operating in the native mode. |
|
|
This feature is now supported on Cisco NCS 5700 series fixed port routers and the Cisco NCS 5500 series routers that have the Cisco NC57 line cards installed and operating in the native and compatible modes. |
|
|
This feature enables the access network to control EVPN PE devices by defining the backup path much before the event of a link failure, thereby reducing the traffic loss. The following keywords are added to the service-carving command:
|
|
|
This feature leverages the NTP clock synchronization mechanism to handle the transfer of DF role from one edge device to another. In this mechanism, the newly added or recovered PE advertises the Service Carving Timestamp along with the current time to peering PEs. This improves convergence by reducing the time for DF election from three seconds to a few tens of milliseconds. The show evpn ethernet-segment command is modified to display the Service-Carving wall clock Timestamp (SCT). |
|
|
This feature is now supported on routers that have Cisco NC57 line cards installed and operate in native and comptability modes. |
|
|
This feature is now supported on Cisco NCS 5700 series fixed port routers and the Cisco NCS 5500 series routers that have the Cisco NC57 line cards installed and operating in the native and compatible modes. |
|
|
With this feature, you can set an active and backup path, in a dual-homed mode based on the nexthop IP address, thereby allowing greater control over traffic patterns. If you are unable to use single-active mode due to hardware, topology, or technological limitations, this feature enables you to direct traffic to a specific remote PE. This feature introduces the preferred nexthop command. |
|
|
This feature is now supported on Cisco NCS 5700 series fixed port routers and the Cisco NCS 5500 series routers that have the Cisco NC57 line cards installed and operating in the native and compatible modes. |
|
|
This feature introduces EVPN Single-Flow-Active multihoming mode to connect PE devices in an access network that run Layer 2 access gateway protocols. In this mode, only the PE that first advertises the host MAC address in a VLAN forwards the traffic in a specific flow. When the primary link fails, the traffic quickly switches to the standby PE that learns the MAC address from the originated path, thereby providing fast convergence. A keyword, single-flow-active is added to the load-balancing-mode command. |

This feature is now supported on Cisco NCS 5700 series fixed port routers and the Cisco NCS 5500 series routers that have the Cisco NC57 line cards installed and operating in the native and compatible modes. |
|
|
In the event of a link failure, this feature enables the router to switch traffic quickly to a precomputed loop-free alternative (LFA) path by allocating a label to the incoming traffic. This minimizes the traffic loss ensuring fast convergence. This feature introduces the convergence reroute command. |
|
|
This feature enables you to send Layer 2 protocol data over IP or other L3 networks. Support of this feature is now extended to the Cisco NCS 5500 series routers. This feature introduces the l2protocol command. |
|
|
In the event of a link failure, this feature enables the router to switch traffic quickly to a precomputed loop-free alternative (LFA) path by allocating a label to the incoming traffic. Thus minimizes the traffic loss ensuring fast convergence. This feature is supported only when PE devices are in an EVPN single-flow-active mode. This feature introduces the convergence mac-mobility command. |
|
|
MPLS |
|
|
This feature is now supported on Cisco NCS 5700 series fixed port routers and the Cisco NCS 5500 series routers that have the Cisco NC57 line cards installed and operating in the native mode. |
|
|
The Generalized Multiprotocol Label Switching (GMPLS) User Network Interface (UNI) creates a circuit connection between two clients (UNI-C) of an optical network. This connection is achieved by signaling exchanges between UNI Client (UNI-C) and UNI Network (UNI-N) nodes. The UNI-C nodes are router nodes and UNI-N nodes are optical nodes. |
|
|
This feature is now supported on Cisco NCS 5700 series fixed port routers and the Cisco NCS 5500 series routers that have the Cisco NC57 line cards installed and operating in the native mode. |
|
|
Multicast |
|
|
This feature enables selecting a bundle member in the control plane to steer the L2 and L3 multicast traffic traversing over bundle at the egress NP. This feature helps optimize fabric bandwidth as the member selection is performed in the control plane. |
|
|
When enabled, this feature provides information on the rate of packets received for a multicast route. Starting this release, the feature is extended on the Cisco NCS 5500 series routers. In addition, this feature is supported on ingress IPv6 stats on routers installed with SE cards. |
|
|
Secondary Subnets and Multicast Source |
This feature enables the use of PIM sparse-mode where a multicast source is on a secondary address subnet. |
|
MLDP Aggregated and Drop Statistics Measurement (v6 ingress stats on J2) |
This feature is now supported on routers that have the Cisco NC57 line cards installed and operate in compatible mode. |
|
This feature is now supported on routers that have the Cisco NC57 line cards installed and operate in compatible mode. |
|
|
In the event of a link failure, this feature enables the router to quickly switch traffic to a precomputed loop-free alternative (LFA) path by allocating a label to the incoming traffic. This minimizes the traffic loss ensuring fast convergence. |
|
|
Routing |
|
|
This feature is now supported on Cisco NCS 5700 series fixed port routers and the Cisco NCS 5500 series routers that have the Cisco NC57 line cards installed and operating in the native mode. |
|
|
Modular QoS |
|
|
With this feature you can configure a desired traffic policy, to which your network complies, by using the bandwidth management technique of two-level traffic shaping. You can also increase the Link Aggregation Group (LAG) sub-interface scale or pseudowires up to 4K. This increased scale value enables you to increase the number of devices connected to your router, resulting in benefits such as increased bandwidth and cost-effective operations. |
|
|
Cisco NC57 Compatibility Mode: QoS Enablement on Layer 2 MPLS/BGP |
This feature is now supported on routers that have the Cisco NC57 line cards installed and operate in the compatibility mode. The following Layer 2 services are supported:
Apart from packet classification, this feature is available for the following QoS operations:
|
|
Conditional Marking of MPLS Experimental Bits for EVPN-VPWS Single-Homing Services |
This feature enables you to differentiate traffic in the MPLS forwarding domain and manage traffic from ingress PE to egress PE based on the MPLS EXP bit of the MPLS header. This feature is supported only for EVPN-VPWS single-homing services, and not supported for EVPN-VPWS multi-homing services. |
|
With this feature, unique policy maps associated to the same template are shared in TCAM, thus enabling scaling of — or creating more number of — policy maps. |
|
|
This feature allows you to share a single instance of QoS policy across multiple sub-interfaces, allowing for aggregate shaping of the sub-interfaces to one rate. The ability to facilitate queue consumption in this manner offers the advantage of saving on QoS and hardware resources, while ensuring that the specified rate is not exceeded. |
|
|
Segment Routing |
|
|
The Segment Routing Mapping Server (SRMS) is a key component of the interworking between LDP and segment routing, enabling SR-capable nodes to interwork with LDP nodes. This release introduces support for SRMS SID-mapping entries to be advertised between IS-IS levels (for example, from Level 1 to Level 2-only and from Level 2 to Level 1), where previously, the mappings were advertised only within the same IS-IS level, but not between IS-IS levels. This feature simplifies and centralizes the deployment of SRMS by removing the requirement of having a mapping server for each IS-IS area. |
|
|
Cisco NC57 Compatible and Native Mode: BVI co-existence with SRTE on same NPU |
This feature is now supported on Cisco NCS 5700 series fixed port routers and the Cisco NCS 5500 series routers that have the Cisco NC57 line cards installed and operating in the native and compatible modes. |
|
With this feature, SRTE calculates a shortest path that satisfies multiple metric bounds. This feature provides flexibility for finding paths within metric bounds, for parameters such as latency, hop count, IGP and TE. |
|
|
TI-LFA provides protection for SR-labeled traffic (IPv4 and IPv6 prefixes associated with a prefix SID) and for other unlabeled IPv4 prefixes. This feature introduces support for protecting unlabeled IPv6 prefixes. |
|
|
This feature is now supported on Cisco NCS 5700 series fixed port routers and the Cisco NCS 5500 series routers that have the Cisco NC57 line cards installed and operating in the native mode. |
|
|
The performance measurement for link delay determines the source and destination IP addresses used in the OAM packet based on the IP address of the interface, where the delay measurement operation is enabled. This feature enables using the IPv6 link-local address as the OAM packet source IP address, when no IPv4 or IPv6 address is configured in the interface. |
|
|
With this feature, you can use SR and MVPN for optimally transporting IP VPN multicast traffic over the SP network, using SR-PCE as a controller. With SR’s minimal source router configuration requirement, its ability to implement policies with specific optimization objectives and constraints, protect against network failures using TI-LFA FRR mechanism, and use SR-PCE to dynamically generate optimal multicast trees (including when topology changes occur in the multicast tree), the SR-enabled SP network can transport IP multicast traffic efficiently. |
|
|
With this feature, NC57 line cards will support SR Policy in native mode. Native mode is used when the chassis contains only NC57 line cards. After you configure the native mode, ensure to reload the router. |
|
|
This feature extends the current TI-LFA functionality to support OSPF. |
|
|
SR OAM for SR Policy (Policy Name / Binding SID / Custom label stack) |
This feature extends SR OAM ping and traceroute function for an SR policy (or binding SID)-LSP end-point combination. This addresses the limitations of the Nil-FEC LSP Ping and Traceroute function which cannot perform a ping operation to a segment list that is not associated with an installed SR policy. Also, it cannot validate egress device-specific SR policies. |
|
You can use this feature to create specific performance measurement delay and liveness profiles, and associate it with an SR policy. This way, a delay or liveness profile can be associated with a policy for which the performance measurement probes are enabled, and performance measurement is precise, and enhanced. The performance-measurement delay-profile sr-policy command was updated with the name profile keyword-argument combination. The performance-measurement liveness-profile sr-policy command was updated with the name profile keyword-argument combination. The performance-measurement delay-measurement command was updated with delay-profile name profile . The performance-measurement liveness-detection command was updated with liveness-profile name profile |
|
|
This feature allows you to verify end-to-end traffic forwarding over an SR Policy candidate path by periodically sending performance monitoring packets. |
|
|
SR-PCE: Flex Algo Aware Policy Computation + Live-Live Disjointness Enhancements |
This feature is now supported on Cisco NCS 5700 series fixed port routers and the Cisco NCS 5500 series routers that have the Cisco NC57 line cards installed and operating in the native and compatible modes. |
|
SR-PCE: IP Unnumbered in Path Computation (ZTP/ZTD use case) |
This feature is now supported on Cisco NCS 5700 series fixed port routers and the Cisco NCS 5500 series routers that have the Cisco NC57 line cards installed and operating in the native and compatible modes. |
|
SR-PCE: Inter-Domain Computation using Redistributed SID (SRTE - BGP-LU Domains Interworking) |
This feature is now supported on Cisco NCS 5700 series fixed port routers and the Cisco NCS 5500 series routers that have the Cisco NC57 line cards installed and operating in the native and compatible modes. |
|
SR-PCE: North-Bound API Enhancements for Cisco Optimization Engine (COE) v1.0 release |

|
|
SRTE: Per Flow (Class) ODN and Automated Steering (GRT and L3 BGP Services) |
This feature is now supported on Cisco NCS 5700 series fixed port routers and the Cisco NCS 5500 series routers that have the Cisco NC57 line cards installed and operating in the native and compatible modes. |
|
This feature is an extension of the SRv6 architecture. It leverages the existing SRv6 Network Programming architecture to encode up to six SRv6 Micro-SID (uSID) instructions within a single 128-bit IPv6 address, called the uSID Container. In addition, this feature leverages the existing SRv6 data plane and control plane with no changes. It also provides low MTU overhead; for example, 6 uSIDs per uSID container results in 18 source-routing waypoints in only 40 bytes of overhead. SRv6 uSID supports the following existing SRv6 functionality:
|
|
|
With this feature, the egress PE can signal an SRv6 Service SID with the BGP global route. The ingress PE encapsulates the IPv4/IPv6 payload in an outer IPv6 header where the destination address is the SRv6 Service SID provided by the egress PE. BGP messages between PEs carry SRv6 Service SIDs as a means to interconnect PEs. |
|
|
With this feature, the egress PE can signal an SRv6 Service SID with the BGP overlay service route. The ingress PE encapsulates the IPv4/IPv6 payload in an outer IPv6 header where the destination address is the SRv6 Service SID provided by the egress PE. BGP messages between PEs carry SRv6 Service SIDs as a means to interconnect PEs and form VPNs. |
|
|
In a typical Anycast scenario, if an advertising node becomes unavailable or unreachable while still advertising its Anycast SID, traffic could still be routed to the node and, as a result, get dropped. This feature allows a node to advertise its loopback address when it’s connected to the domain, and to track the loopback addresses of the other nodes in the domain. If a node becomes unavailable or unreachable, it stops advertising its loopback address, allowing for a new path to be computed. |
|
|
This feature extends Anycast SIDs with weighted nodes. Weighted Anycast nodes advertise a cost (weight) along with the Anycast SID. Traffic is then distributed according to the weights. Weighted Anycast SIDs allow for highly available paths with node redundancy and path optimality that provide Fast ReRoute (FRR) for node failure of service provider edge (PE) routers and ABR/ASBRs nodes in multi-domain networks. |
|
|
System Management |
|
|
Any delays on Precision Time Protocol (PTP) paths can impact PTP accuracy and in turn impact clock settings for all devices in a network. This feature allows you to configure the static asymmetry such that the delay is accounted for and the PTP synchronization remains accurate. The delay-symmetry command is introduced for this feature. |
|
|
SIA license grants you access to the latest software upgrades which contain new features, bug fixes, and security enhancements for devices on your network. Also, it enables the consumption of Advanced and Essential Right-to-Use (RTU) licenses on your device, and allows portability of these RTU licenses from one device to another. |
|
|
System Monitoring |
|
|
This feature is now supported on Cisco NCS 5700 series fixed port routers and the Cisco NCS 5500 series routers that have the Cisco NC57 line cards installed and operating in the native mode. |
|
|
System Security |
|
|
With this feature, a snapshot of the filesystem metadata such as when the file was created, modified, or accessed is collected at each configured interval. In addition to displaying the changes that the file underwent as compared to the previous snapshot, the inventory helps in maintaining data integrity of all the files in the system. |
|
|
This algorithm is now supported on Cisco IOS XR 64-bit platforms when establishing SSH sessions. It is a modern and secure public-key signature algorithm that provides several benefits, particularly resistance against several side-channel attacks. Prior to this release, DSA, ECDSA, and RSA public-key algorithms were supported. This command is modified for this feature: |
|
|
Integrity Measurement Architecture (IMA) is a Linux-based utility that attests and appraises the integrity of a system security, at runtime. In this release, IMA introduces the following IMA optimization aspects:
|
|
|
With this feature, when you key in a password or secret, it is not displayed on the screen. This enhances security. The feature is enabled by default. The following options are added to the username command:
|
|
|
This feature allows you to generate and securely store crypto key pair for the Ed25519 public-key signature algorithm on Cisco IOS XR 64-bit platforms. This signature system provides fast signing, fast key generation, fool proof session keys, collision resilience, and small signatures. The feature also facilitates integration of Cisco IOS XR with Cisco Crosswork Trust Insights. Commands introduced for this feature are: show crypto key mypubkey ed25519 Commands modified for this feature are: |
|
|
This feature allows you to set a limit on the number of user authentication attempts allowed for SSH connection, using the three authentication methods that are supported by Cisco IOS XR. The limit that you set is an overall limit that covers all the authentication methods together. If the user fails to enter the correct login credentials within the configured number of attempts, the connection is denied and the session is terminated. This command is introduced for this feature: |
|
|
This feature helps in verifying the authenticity of an installable package. A Known Good Value (KGV) is calculated and published for each package. The installed and running software is compared with the KGV to determine whether the package is genuine or not. These two values are displayed only in the Yang model output. No CLI commands are provided to view these values. |
|
|
This feature adds new public-key algorithms that use X.509v3 digital certificates for SSH authentication. These certificates use a chain of signatures by a trusted certification authority to bind a public key to the digital identity of the user who is authenticating with the SSH server. These certificates are difficult to falsify and therefore used for identity management and access control across many applications and networks. Commands introduced for this feature are: This command is modified for this feature: |
|
|
System Setup and Software Installation |
|
|
To comply with US DoD, an option to enable display of login banner is introduced. The login banner provides information such as number of successful and unsuccessful login attempts, time stamp, login method, and so on. The login-history command is introduced. |
|
|
This feature allows devices in the network to establish a secure connection with the ZTP server and authenticate information using a three-step validation process involving validation of the network device, the ZTP server, and onboarding information. This eliminates security risks or malicious actions during remote provisioning.
|
|
|
Zero Touch Provisioning is now extended to support provisioning using removable storage, such as USB drive. |
|
|
Telemetry |
|
|
This feature leverages machine learning to detect and retrieve important network-state changes on the router. Relevant data is filtered and exported to the network management system for analysis or troubleshooting purposes. ADT significantly simplifies the configuration of streaming telemetry, and you are no longer required to manually choose sensor paths or tune the cadence at which counters have to be collected. |
|
|
This feature synchronises the timestamp for accurate calculation of data rate from the router, wherein the counters are read from the hardware. The counters are updated only when the collector reads the counters from hardware, irrespective of the number of times the MDT client polls data. With hardware timestamping in rate computation while streaming periodic statistics, the spikes due to the inconsistent timestamp from cache files is resolved. |
|
|
Streaming Digital Optical Monitoring (DOM) data from the router |
This feature streams fiber optic transceiver parameters such as optical input or output levels, temperature, laser bias current, supply voltage, receiver power, bias threshold, etc., in real-time. This helps network operators to easily locate a fiber link failure, thereby simplifying the maintenance process, and improving overall system reliability. Sensor paths introduced for this feature are:

Other Important Information
-
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.
Supported Transceiver Modules
To determine the transceivers that Cisco hardware device supports, refer to the Transceiver Module Group (TMG) Compatibility Matrix tool.
Supported Modular Port Adapters
For the compatibility details of Modular Port Adapters (MPAs) on the line cards, see the datasheet of that specific line card.
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.
