Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Control plane, forwarding plane and management plane elements, centralized network timing, full device programmability, and services orchestration. The Cisco® NCS 560-4 Route Switch Processor 4 (RSP4) is the powerful centralized engine that is designed to accommodate new programmable deployment models and convergence of advanced Layer 2 and Layer 3 services. The NCS 560-4 RSP4 (Figure 1) addresses the evolving requirements for converged service provider networks, delivering a variety of advanced technologies for mobile xHaul, Radio Access Network Aggregation (RAN), carrier Ethernet, and Data Center Interconnect (DCI), such as MPLS, segment routing, segment routing traffic engineering, and advanced Ethernet VPN technologies. With in-built trust anchor hardware infrastructure and software enabled security features, NCS 560-4 RSP4 is trusted and secured platform. The NCS 560-4 RSP4 helps service providers add innovative traffic management, packet switching, intelligent routing, and service creation features.

Product overview

The NCS 560-4 RSP4 modules contain separate control plane, forwarding (data) plane, and management plane components. These include the main control plane CPU for the Cisco IOS-XR® software operating system and platform control software. The forwarding (data) plane packet processing and traffic management are performed by the carrier Ethernet Application-Specific Integrated Circuit (ASIC) embedded in the RSP.

The Cisco NCS 560-4 Route Switch Processor 4 also supports a field-replaceable Global Navigation Satellite System (GNSS) module that allows direct interface to external antennas. The GNSS module supports several satellite systems, such as the Global Positioning System (GPS), GLONASS, GALILEO, BEIDU, QZSS, and SBAS.

The Cisco NCS 560-4 Route Switch Processor 4 is available in two different memory (TCAM) configurations to support large- and extra-large-scale capabilities. The software is identical between the two RSPs.

The Cisco NCS 560-4 interface module support is not dependent on the type of RSP used. The NCS 560 Series Interface Modules Datasheet contains the slot compatibility matrix for the NCS 560-4 RSP.

Features and benefits



Carrier Ethernet

Delivers essential carrier Ethernet technologies such as Hierarchical Quality of Service (H-QoS), IPv4, IPv6, MPLS, segment routing, Segment Routing Traffic Engineering (SR-TE), On-Demand Next Hop (ODN), Topology Independent Loop Free Alternate (TI-LFA), Layer 2 VPN (VPLS/H-VPLS), Ethernet VPN (EVPN-VPWS), and Layer 3 VPN services. It provides line-rate performance and incorporates innovative traffic management capabilities while providing intelligent packet switching and routing operations. Device programmability and services orchestration capabilities for carrier Ethernet are embedded as part of the Evolved Programmable Network Solution Architecture.

Is MEF CE 3.0 Certified.

Service enhancement

Provides advanced per-traffic-class metering and offers bidirectional packet-count and byte-count statistics. The service offering is enhanced with Operations, Administration, and Maintenance (OAM) functionality that includes Layer 2 Connectivity Fault Management (CFM), IP Service-Level Agreements (IP SLA) for Layer 3, and MPLS OAM.

Service scale

Provides flexible and high service scalability in a small footprint, delivering high performance and scale for point-to-point and multipoint services, accommodating the requirements from the most demanding wireline and wireless applications.

Clocking and timing services

Offers integrated support for the Global Navigation Satellite System (GNSS), Building Integrated Timing Supply (BITS), 10 MHz, 1 Pulse Per Second (1 PPS), and Time-Of-Day (TOD) interfaces, crucial functions required in a modern unified network. As the central system clocking and timing functions for the NCS 560-4 Router, the Cisco NCS 560 RSPs support Synchronous Ethernet (SyncE) and IEEE 1588-2008 Precision Time Protocol (PTP). The NCS 560-4 router can act as an IEEE 1588-2008 ordinary clock, boundary clock, end-to-end transparent clock, and primary clock function in an IEEE 1588-2008 timing domain.

High availability and modularity

Delivers optional intrachassis hardware redundancy for all hardware components and supports software redundancy with In-Service Software Upgrade (ISSU) support when a pair of route switch processor 4s is inserted in the Cisco NCS 560 system chassis fully modular platform.

With two RSPs inserted in the Cisco NCS 560-4 router, one RSP operates in active mode, and the other RSP operates in hot standby mode. The Cisco NCS 560 RSP is a Field-Replaceable Unit (FRU), and it can be Online Inserted and Removed (OIR) while the Cisco NCS 560 system is operating. The removal or failure of the active RSP in the Cisco NCS 560 system results in the automatic switchover to the standby RSP.

Management interfaces

Contains the Out-Of-Band (OOB) management interfaces for the system. To offer flexible access to the router, a variety of interfaces are available for management access to the platform, including a dual-mode console port that functions as either a USB console or a serial console port.

In addition to the serial console access, the Cisco NCS 560 RSP contains an Ethernet management port that has no interaction with actual carrier Ethernet ASIC traffic. In addition to the OOB control interfaces, a USB port can connect USB flash devices for loading Cisco IOS software images and configurations on the platform.

Industry-leading, carrier-class Cisco IOS XR software

The Cisco NCS 560-4 router delivers extra-large scale, service flexibility, and high availability into access and (pre)aggregation networks. It is powered by Cisco IOS XR software, an innovative self-healing, distributed operating system designed for always-on operation. Cisco IOS XR software supports a Software-Maintenance-Update (SMU) capability, which allows bug fixing or even small feature releasing without interrupting existing services.

The Cisco IOS XR software provides scale and serviceability for service providers by:

      Supporting the complete set of Cisco IOS XR software features for a consistent experience

      Scaling advanced service delivery without affecting system performance

      Integrating applications in the network, improving security, reliability, and simplicity

      Facilitating programmability for service orchestration

The initial software support for the Cisco NCS 560-4 router is with IOS XR 6.6.25 software
