  • 4 x 100G

Note
Cisco N540-24Q8L2DD-SYS and N540X-4Z14G2Q-A/D routers are not supported in Cisco IOS XR Release 7.3.2.

The following features are supported only on N540-FH-CSR-SYS and N540-FH-AGG-SYS variants.

Feature Description

L2VPN

EVPN-VPWS support to RoE interface

This feature extends support in carrying the Radio over Ethernet (RoE) packets from Cell Site Router (CSR) to the aggregation router.

Modular QoS

Low Latency Queuing for Specific QoS Flows

This feature allows you to configure low latency or priority for specific QoS flows at the class-level within a policy map. It enables delay-sensitive data to be prioritized and transmitted before other packets in other queues.

The following features are supported only on N540-28Z4C-SYS-A/D, N540X-16Z4G8Q2C-A/D, N540-12Z20G-SYS-A/D, and N540X-12Z16G-SYS-A/D variants.

Feature Description

System Security

CiscoSSH

This release introduces CiscoSSH, a newer implementation of SSH on NCS 540 Small Density, NCS 540 Large Density, NCS 540 Medium Density (except N540-ACC-SYS, NC540X-ACC-SYS, N540-24Z8Q2C-SYS variants).

CiscoSSH leverages OpenSSH implementation, by using the Linux TCP/IP stack to transmit and receive SSH packets over the management Ethernet interface and line card interfaces on the router. CiscoSSH provides additional security features like FIPS compliance and X.509 digital certification. It supports packet path features like MPP, ACL and VRF support, and ensures interoperability with various existing SSH implementations.

Note

 

Cisco IOS XR SSH, the SSH implementation that existed prior to this release, is now deprecated on all variants of NCS 540 except for N540-ACC-SYS, NC540X-ACC-SYS, N540-24Z8Q2C-SYS.

System Setup

ZTP over Layer 2

Previously available over Layer 3, this feature is now available to auto-provision your routers and DHCP devices on Layer 2 networks.

This functionality is essential because many service provider topologies have services configured for various Layer 2 VLAN tags, requiring cost-effective and reliable provisioning.

The following features are supported only on N540-ACC-SYS, N540X-ACC-SYS, N540-24Z8Q2C-SYS, N540-28Z4C-SYS, N540-28Z4C-SYS-A/D, N540X-16Z4G8Q2C-A/D, N540-12Z20G-SYS-A/D, N540X-12Z16G-SYS-A/D, N540X-6Z18G-SYS-A/D, N540X-8Z16G-SYS-A/D, and N540X-4Z14G2Q-A/D variants.

Feature Description

System Security

Graceful Termination of SSH Sessions

This functionality gracefully terminates the active SSH sessions on the router by returning a successful exit code (0) to the SSH client. This functionality is mainly helpful for automation scenarios such as image installation on a router initiated by a client through an SSH session, where the router reloads automatically post-upgrade. This functionality existed earlier with Cisco IOS XR SSH and is now getting introduced with CiscoSSH.

Without this functionality, the SSH sessions terminated abruptly by returning a failure error code (255) to the SSH client, causing the automation scripts to fail.

The new functionality is applicable only for upgrade and router reload scenarios; not for RP failovers and active RP reload scenarios.

SSH Port Forwarding

With this feature enabled, the SSH client on a local host forwards the traffic coming on a given port to the specified host and port on a remote server, through an encrypted SSH channel. Legacy applications that do not otherwise support data encryption can leverage this functionality to ensure network security and confidentiality to the traffic that is sent to remote application servers.

This feature introduces the ssh server port-forwarding local command.

Note

 

For the following Cisco NCS 540 router variants, this feature is supported with Cisco IOS XR SSH:

  • N540-ACC-SYS

  • N540X-ACC-SYS (Premium)

  • N540-24Z8Q2C-SYS

For all other Cisco NCS 540 router variants, this feature is supported with CiscoSSH, an OpenSSH-based implementation of SSH.

Programmability

Cisco IOS XR mpls-ping-act and Cisco IOS XR mpls-traceroute-act YANG data model

This feature introduces the Cisco-IOS-XR-mpls-ping-act and Cisco-IOS-XR-mpls-traceroute-act YANG data models to accommodate OAM RPCs for MPLS and SR-MPLS.

You can access these Cisco IOS XR native data models from the Github repository.

Routing

Fast Path - Graceful Conflict Identification or Resolution for Encapsulation-ID

BGP

BGP PIC: Export of Backup Path Agnostic to its Multipath Eligibility

Prior to this release, you could only import the backup paths of a prefix to the respective VRFs only when the backup paths are multipath eligible. For backup paths to be multipath eligible, all the following attributes in the backup paths must be the same: weight, local preference, autonomous system path, origin code, Multi Exit Discriminator (MED), and Interior Gateway Protocol (iGP) distance. Also, the next hop router for each multipath must be different. This feature introduces flexibility to allow the import of backup paths to the VRF even if the said attributes are not the same.

Segment Routing

Dual-Stack L3VPNServices (IPv4, IPv6) (SRv6 Micro-SID)

This feature introduces support for Dual-stack (VPNv4/VPNv6) VRFs. VPNv4/VPNv6 Dual-stack supports both IPv4 (uDT4) and IPv6 (uDT6) based SRv6 L3VPN service on the same interface, sub-interface, or VRF.

SRv6 Services: EVPN VPWS—All-Active Multi-Homing (SRv6 Micro SID)

This feature provides an ELINE (P2P) service with all-active multihoming capability over an SRv6 network.

All-Active Multi-Homing enables an operator to connect a customer edge (CE) device to two or more provider edge (PE) devices to provide load balancing and redundant connectivity. With All-Active Multi-Homing, all the PEs can forward traffic to and from the multi-homed device.

BGP-LU Inter-AS Option-C Interworking with LDP and IGP SR-MPLS using Proxy BGP-SR

This feature extends the current Proxy BGP-SR functionality by allowing the BGP-LU ASBR router with Proxy BGP-SR configured to also interconnect attached LDP domains.

The Proxy BGP-SR feature allows interconnection of IGP SR-MPLS domains and legacy domains via BGP-LU Inter-AS option-C. It provides a prefix-to-SID mapping for BGP-LU prefixes that are learned without a Prefix-SID.

SR-TE BGP Soft Next-Hop Validation For ODN Policies

This feature addresses BGP Next-Hop reachability issues through BGP Next-Hop soft validation, and also enhances BGP best path selection.

  • nexthop validation color-extcomm disable

  • nexthop validation color-extcomm sr-policy

  • bgp bestpath igp-metric sr-policy

SR-TE PCE Groups

This feature allows an SR policy to be delegated to a set of PCE servers configured under a PCE group. Multiple PCE groups can be configured to allow SR policies on the same head-end to be delegated to different sets of PCEs.

With this functionality, an operator can designate sets of PCEs for various purposes, such as PCE-per-service-type or PCE-per-wholesale-customers.

Autoroute Include

This feature allows you to steer specific IGP (IS-IS, OSPF) prefixes, or all prefixes, over non-shortest paths and to divert the traffic for those prefixes on to an SR-TE policy.

SR-PCE: North-Bound API for SRv6 and Flexible Algorithm in Cisco Optimization Engine (COE) v3.0 release

The SR-PCE provides a north-bound HTTP-based API to allow communication between SR-PCE and external clients and applications. The Cisco Crosswork Optimization Engine is an application that leverages the SR-PCE.

This release adds support for the following:

  • Reporting of Flexible Algorithm participation and definitions

  • SRv6 topology information (nodes, links, Node uSIDs and Adj uSIDs)

  • SRv6 uSID list and uB6 SIDs allocated for a policy

For more information, refer to the Cisco Crosswork Optimization Engine User Guides.

IP Endpoint Delay Measurement and Liveness Monitoring

This feature measures the end-to-end delay and monitors liveness of a specified IP endpoint node, including VRF-aware (awareness of multiple customers belonging to different VRFs).

This feature is supported on IPv4, IPv6, and MPLS data planes.

OSPF: Microloop Avoidance for Flexible Algorithm

This feature extends the current OSPF Flexible Algorithm functionality to support Microloop Avoidance.

SRv6TE Phase1: PCC/PCE (PCEPv6) uSID Introduction - PCE Delegated, Constraints: Disjoint, affinity, Metric: IGP, TE, Latency, L3 Services ODN/AS

This feature brings the Segment Routing Traffic Engineering features to the SRv6 data plane.

This release supports the following features:

  • SRv6-TE with SRv6 micro-SIDs (uSIDs)

  • SRv6 policies

  • Manual SRv6 policies

  • On-Demand SRv6 policies - SR On-Demand Next-Hop (SR-ODN)

  • Automated steering for Layer 3-based BGP services (IPv4 L3VPN, IPv6 L3VPN, IPv4 BGP global, IPv6 BGP global)

  • SRv6-aware Path Computation Element (PCE)

  • PCEPv6

  • Path computation optimization objectives (TE, IGP, latency)

  • Path computation constraints (affinity, disjointness)

Use user-class Option 'xr-config' Instead Of 'exr-config' To Provision ZTP

In Cisco IOS XR Release 7.3.1 and earlier, the system accepts the device sending user-class = "exr-config"; however starting Cisco IOS XR Release 7.3.2 and later, you must use only user-class = "xr-config".

In Cisco IOS XR Release 7.3.2 and later, use:

host cisco-rp0 {
   hardware ethernet e4:c7:22:be:10:ba;
   fixed-address 172.30.12.54;
   if exists user-class and option user-class = "iPXE" {
      filename = "http://172.30.0.22/boot.ipxe";
   } elsif exists user-class and option user-class = "xr-config" {
      filename = "http://172.30.0.22/scripts/cisco-rp0_ztp.sh";
   }
}
