    Product Overview

    The Cisco® ASR 9000 Series Ethernet Line Cards are the latest generation of service-provider-focused Carrier Ethernet line cards from Cisco. These line cards deliver economical, scalable, highly available, line-rate Ethernet and IP/Multiprotocol Label Switching (IP/MPLS) edge services. The Cisco ASR 9000 Series Line Cards and other Cisco ASR 9000 Series platform components are designed to provide the fundamental infrastructure for scalable Carrier Ethernet and IP/MPLS networks, supporting profitable business, residential, and mobile services (Figure 1).

    Figure 1.      Cisco ASR 9000 Series Ethernet Line Cards

    Features and Benefits

    Each Cisco ASR 9000 Series Ethernet Line Card provides hierarchical quality of service (HQoS) and simultaneous support for both Layer 2 and Layer 3 services and features, allowing operators to qualify and stock a single line card that can be deployed in any combination of Layer 2 and Layer 3 applications. This capability helps to reduce capital expenditures (CapEx) and operating expenses (OpEx), as well as reduce the time required to develop and deploy new services. With support for up to 512,000 queues, 32,000 interfaces, 1.3 million routes, 1 million MAC addresses, and 36,000 VPNs, the Cisco ASR 9000 Series Ethernet Line Cards set a new standard for service density, allowing operators to offer predictable, managed transport services while optimizing the use of network assets.

    With their synchronization circuitry and dedicated backplane timing traces for accessing the route switch processor’s (RSP’s) Stratum-3 subsystem, the Cisco ASR 9000 Series Ethernet Line Cards provide standards-based line-interface functions for delivering and deriving transport-class network timing, enabling support of network-synchronized services and applications such as mobile backhaul and time-division multiplexing (TDM) migration. Recognizing that real-time media dominate next-generation services, Cisco has integrated media-monitoring technology into the Cisco ASR 9000 Series Ethernet Line Cards. This multimedia technology supports real-time, standards-based monitoring and statistics collection of real-time video and voice flows, delivering proactive maintenance and management of today’s media-rich services.

    Addressing the advantages of consolidating IP and dense wavelength division multiplexing (DWDM) networking, G.709 with Advanced Forward Error Correction (FEC) is provided. G.709 provides visibility into the DWDM transmission system to provide rapid detection and recovery from transmission-layer and DWDM impairments. Before traffic is lost and a link outage occurs, G.709 can also be configured for proactive protection if signal degradation is detected. The Advanced FEC extends transmission-layer performance, delivering extended performance over an amplified system without the cost of regeneration or transponders.

    Product Specifications

    Table 4 provides product specifications. Scale support is software and hardware dependent.

    Table 4.       Product Specifications



    Cisco IOS XR Software support

      Modular software design: Cisco IOS XR Software demonstrates Cisco networking leadership in helping customers realize the power of their networks and the Internet. The software provides exceptional routing-system scalability, high availability, service isolation, and manageability to meet the mission-critical requirements of next-generation networks.
      Operating system infrastructure protection: Cisco IOS XR Software provides a microkernel architecture that forces all but the most critical functions, such as memory management and thread distribution, outside of the kernel. This setup prevents failures in applications, file systems, and even device drivers from causing widespread service disruption.
      Process and thread protection: Each process – even individual process threads – occurs in its own protected memory space, and communications between processes are accomplished through well-defined, secure, and version-controlled application programming interfaces (APIs). This setup significantly minimizes the effect that any process failure can have on other processes.
      Process restart: The line cards offer the ability to restart critical control-plane processes both manually and automatically in response to a process failure, rather than restarting the entire OS. This feature helps to support the Cisco IOS XR Software goal of continuous system availability and allows for quick recovery from process or protocol failures with minimal disruption to customers or traffic.
      State checkpointing: The line cards offer the capability to maintain a memory and critical operating state across process restarts so that routing adjacencies and signaling state can be maintained during an RSP switchover.

    Flexible Ethernet services

      Ethernet virtual connections (EVCs): Ethernet services are supported using individual EVCs to carry traffic belonging to a specific service type or end user through the network. EVC-based services can be used in conjunction with MPLS-based L2VPNs and native Ethernet switching deployments.
      Flexible VLAN classification: VLAN classification into EFPs includes single-tagged VLANs, double-tagged VLANs (QinQ and 802.1ad), contiguous VLAN ranges, and noncontiguous VLAN lists.
      IEEE bridging: The line cards support native bridging based on IEEE 802.1Q, IEEE 802.1ad, 802.1ah, and QinQ VLAN encapsulation mechanisms.
      IEEE 802.1s Multiple Spanning Tree (MST): MST extends the 802.1w Rapid Spanning Tree Protocol (RSTP) to multiple spanning trees, providing rapid convergence and load balancing.
      MST Access Gateway: The MST Access Gateway provides a resilient, fast-convergence mechanism for aggregating and connecting to Ethernet-based access rings.

    L2VPN services

      Virtual Private LAN Services (VPLS): These services are included in a class of VPN that supports the connection of multiple sites in a single bridged domain over a managed IP/MPLS network. VPLS presents an Ethernet interface to customers, simplifying the LAN and WAN boundary for service providers and customers, and supporting rapid and flexible service provisioning, because the service bandwidth is not tied to the physical interface. All services in a VPLS appear to be on the same LAN, regardless of location.
      Hierarchical VPLS (HVPLS): HVPLS provides a level of hierarchy at the edge of the VPLS network for increased scale. Two options of HVPLS are supported: QinQ access and Ethernet over MPLS (pseudowire) access.
      Virtual Private Wire Service (VPWS) with Ethernet over MPLS (EoMPLS): EoMPLS transports Ethernet frames across an MPLS core using pseudowires. Individual EFPs or traffic from an entire port can be transported over the MPLS backbone using pseudowires to an egress interface or subinterface.
      Pseudowire redundancy: Pseudowire redundancy supports the definition of a backup pseudowire to protect a primary pseudowire that fails.
      G.8032: G.8032 is a feature that provides the sub-50-ms protection for Ethernet traffic in a ring topology.  The implementation on the Cisco ASR 9000 Series is compliant with version 2 of the ITU-T standard.
      Multisegment pseudowire stitching: Multisegment pseudowire stitching is a method for interworking two pseudowires together to form a cross-connect relationship.


      IPv4 Multicast: The line cards support Internet Group Management Protocol Versions 2 and 3 (IGMPv2 and v3), Protocol Independent Multicast-Source Specific Multicast (PIM-SSM), PIM sparse mode (PIM-SM), PIM SSM Mapping, Multicast Source Discovery Protocol (MSDP), Multicast VPN, and Anycast rendezvous point (RP).
      IGMP v2 and v3 snooping: This Layer 2 mechanism efficiently tracks multicast membership on an L2VPN network. Individual IGMP joins are snooped at the VLAN level or pseudowire level and then results are summarized into a single upstream join message. In residential broadband deployments, this scenario allows the network to send only channels that are being watched to the downstream users.


      Ethernet OA&M (EOAM) (IEEE 802.3ah): Ethernet link layer OA&M is a vital component of EOAM that provides physical-link OA&M to monitor link health and assist in fault isolation. Along with 802.1ag, Ethernet link layer OA&M can be used to assist in rapid link-failure detection and signaling to remote end nodes of a local failure.
      EOAM (IEEE 802.1ag): Ethernet Connectivity Fault Management (E-CFM) is a subset of EOAM that provides numerous protocols and procedures that allow discovery and verification of the path through 802.1 bridges and LANs.
      EOAM (ITU Y.1731): Y.1731 provides two separate feature sets: Fault Management (FM) and Performance Monitoring (PM).  Fault Management builds on 802.1ag message types to allow verification of the Ethernet network and provide a toolset for troubleshooting any found faults.  Performance Monitoring allows service providers to provide SLAs to their end customers by measuring the delay, latency, and loss across an Ethernet network.
      Ethernet LMI (E-LMI): Ethernet Local Management Interface (E-LMI) is a protocol between the customer-edge (CE) device and the provider-edge (PE) device. It runs only on the PE-to-CE User Network Interface (UNI) link and notifies the CE device of connectivity status and configuration parameters of Ethernet services available on the CE port.
      MPLS OA&M: The line cards support label switched path (LSP) ping, LSP traceroute, and VCCV.

    Layer 3 routing

      IPv4 routing: Cisco IOS XR Software supports a wide range of IPv4 services and routing protocols, including Border Gateway Protocol (BGP), Intermediate System-to-Intermediate System (IS-IS), Open Shortest Path First (OSPF), Routing Information Protocol (RIP), static, IPv4 Multicast, Routing Policy Language (RPL), and Hot Standby Router Protocol (HSRP) and Virtual Router Redundancy Protocol (VRRP) features.
      IPv6 routing: Cisco IOS XR Software supports IPv6 services, including OSPFv3, IS-IS, Virtual Router Redundancy Protocol (VRRPv6), DHCPv6 relay, and static routing.
      BGP Prefix Independent Convergence (PIC): BGP PIC provides the ability to converge BGP routes using the fast-convergence innovation that is distinctive to Cisco IOS XR Software.


      MPLS L3VPN: The IP VPN feature for MPLS allows a Cisco IOS Software or Cisco IOS XR Software network to deploy scalable IPv4 Layer 3 VPN backbone services. An IP VPN is the foundation that companies use for deploying or administering value-added services, including applications and data-hosting network commerce, and telephony services to business customers.
      Carrier supporting carrier (CSC): CSC allows an MPLS VPN service provider to connect geographically isolated sites using another backbone service provider and still maintain a private address space for its customer VPNs. CSC is implemented as defined by IETF RFC 4364.
      Selective VRF Download:  This feature provides the ability to selectively download VRF forwarding information base (FIB) entries to line cards that have VRF membership for each VRF.  This provides larger FIB scale at a chassis level without burdening line cards with unnecessary FIB entries.
      6PE and 6VPE: 6PE and 6VPE allow for introduction of IPv6 from the edge, in a scalable way, without any IPv6 addressing restrictions and without putting a well-controlled IPv4 backbone in jeopardy. This provides a solution that has minimal risk and operational cost with no effect on either the existing IPv4/MPLS backbone or edge and customer IPv6 networks.

    MPLS Traffic Engineering (TE)

      MPLS Traffic Engineering: Cisco IOS XR Software supports MPLS protocols, such as Traffic Engineering-Fast Reroute (TE-FRR), Resource Reservation Protocol (RSVP), Label Distribution Protocol (LDP), and Targeted Label Distribution Protocol (T-LDP).
      MPLS Traffic Engineering Preferred Path: Preferred tunnel path functions let you map pseudowires to specific traffic engineering tunnels. Attachment circuits are cross-connected to specific MPLS TE tunnel interfaces instead of remote provider-edge router IP addresses (reachable using Interior Gateway Protocol [IGP] or LDP).
      MPLS Traffic Engineering Auto-Bandwidth: MPLS TE automatic bandwidth adjustment provides the means to automatically adjust the bandwidth allocation for traffic engineering tunnels based on their measured traffic load.
      Point to Multipoint (P2MP) Traffic Engineering:  The MPLS P2MP TE feature allows you to forward MPLS traffic from one source to multiple destinations. P2MP TE provides a single point of traffic control and the ability to configure explicit paths to optimize traffic distribution, while benefitting from extending FRR protection to P2MP TE sub-LSPs.

    High availability

      MPLS TE-FRR: MPLS Traffic Engineering-FRR delivers Layer 3 protection switching for networks currently configured with MPLS LSP. MPLS TE-FRR provides temporary rerouting around a failed link, node, or path.
      Bidirectional Forwarding Detection (BFD): BFD is a detection protocol that is designed to provide fast-forwarding path-failure detection times for all media types, encapsulations, topologies, and routing protocols.
      802.3ad Link Aggregation Bundles: The line cards support a bundle of multiple links to provide added resiliency and the ability to load-balance traffic over multiple member links.
      Multichassis Link Aggregation Group (MC-LAG): MC-LAG provides a standards-based 802.3ad bundle for a connecting device to reach a pair of Cisco ASR 9000 Series Aggregation Services Routers that appear as a single router to the connecting device. Rapid restoration times are possible even if there is a link or node failure, which improves the operational environment for the connecting device. MC-LAG can work with a long list of solutions on the Cisco ASR 9000 Series routers, such as business L2VPN and L3VPN, residential service backhaul, mobile aggregation, and service provider edge.


    Cisco IOS XR Software manageability: This feature provides industry-standard management interfaces, including modular command-line interface (CLI), Simple Network Management Protocol (SNMP), Cisco Discovery Protocol (CDP), Link Layer Discovery Protocol (LLDP) and native XML interfaces.

    Smart Call Home (SCH): This proactive support capability identifies and reports problems before they affect your business. This allows for less time troubleshooting and a speedier resolution experience for network issues.

    Cisco Active Network Abstraction (ANA): Cisco ANA is a flexible, vendor-neutral management framework for a multitechnology, multiservice network environment. Operating between the network and the operations-support-system (OSS) layer, Cisco ANA aggregates virtual network elements (VNEs) into a software-based virtual network, much as real network elements create the real-world network. Cisco ANA dynamically discovers network components and tracks the status of network elements in near real time.Cisco ANA offers service providers:

      Simplified integration of OSS applications with network information
      A flexible common infrastructure for managing network resources
      Consistent procedures and interfaces for all network elements


    Cisco IOS XR Software: Cisco IOS XR Software provides comprehensive network security features, including access control lists (ACLs); control-plane protection; routing authentications; authentication, authorization, and accounting (AAA) and TACACS+; Secure Shell (SSH) Protocol; SNMPv3; and leading Routing Policy Language (RPL) support.

    Layer 2 ACLs: You can use this security feature to filter packets under an EVC based on MAC addresses.

    Layer 3 ACLs: This feature provides ACL matching by IPv4 packet attributes.

    Security: Many critical security features are supported:

      802.1ad Layer 2 Control Protocol (L2CP) and bridge-protocol-data-unit (BPDU) filtering
      MAC limiting per EFP or bridge domain
      Unicast, multicast, and broadcast storm-control blocking on any interface or port
      Unknown Unicast Flood Blocking (UUFB)
      Dynamic Host Configuration Protocol (DHCP) snooping
      Unicast Reverse Path Forwarding (URPF)

    System Requirements

    The Cisco ASR 9000 Series Line Cards may be deployed in both the 10-slot and 6-slot chassis. The Cisco ASR 9000 Series delivers superior scale, service flexibility, and high availability into access and aggregation networks. It is powered by Cisco IOS XR Software – an innovative self-healing, distributed operating system designed for always-on operation while scaling system capacity up into the Tbps.

    Cisco ASR 9000 Series Carrier Ethernet applications include business services such as L2VPN and L3VPN, IPTV, Content Delivey Networks (CDNs), and mobile backhaul transport networks. Features supported include Ethernet Services; L2VPN; IPv4, IPv6, and L3VPN; Layer 2 and Layer 3 multicast; IP over DWDM (IPoDWDM); Synchronous Ethernet (SyncE); EOAM;  MPLS OA&M; Layer 2 and Layer 3 ACLs; HQoS; MPLS TE-FRR; MC-LAG; Integrated Routing and Bridging (IRB); Nonstop Forwarding (NSF); and Nonstop Routing (NSR).

    The Cisco ASR 9000 Series also has a comprehensive portfolio of shared port adaptors (SPAs) to facilitate the multiservice edge (MSE) and Ethernet MSE (E-MSE) capability on the Cisco ASR 9000 Series. The Cisco ASR 9000 Series MSE and E-MSE capabilities allow enterprises to offer powerful business VPN services with strong SLA enforcement. This complements the high-queue (-E) class of Ethernet linecards that are designed for high-touch high-scale business-VPN E-MSE services. Such services typically require simultaneous scale increases across multiple dimensions, for example, the number of Virtual Route Forwarding (VRF) interfaces, IPv4 and IPv6 route scaling, Bidirectional Forwarding Detection (BFD) sessions and instances of Border Gateway Protocol (BGP) Non-Stop Routing (NSR) interfaces. A Cisco ASR 9000 Series system configuration requiring high multiple dimensional scale requires the Cisco ASR 9000 Series Route Switch Processor with 8 GB memory to support the increased system scale.
