• Forwarding Reliability: Zero packet loss during RSP stateful switchover events, stable wire-speed unicast and multicast packet forwarding at full rated throughput
• Multi-rate port bandwidth: Each QSFP28 port runs full line rate at 100G, 40G, or breakout aggregated lower-speed bandwidth
• Typical Power Consumption: Approximately 320W per line card, with power-saving mode for unused port slices to reduce idle power draw.

Physical & Environmental Parameters

4. SE (Service Edge) Exclusive Expanded Hardware Resource Profile

1. Massive Hierarchical QoS Queue Pool
   Expanded multi-level hierarchical queuing resources supporting hundreds of thousands of independent subscriber traffic profiles, dedicated LLQ low-latency scheduling for real-time voice, IPTV, VoD, and 5G mobile backhaul media streams; multi-level per-subscriber traffic policing, bandwidth shaping and weighted fair queuing (WFQ).
2. High-Scale Policer & Packet Classification Engines
   Large pools of hardware offloaded two-color and three-color multi-rate policers; high-capacity ingress/egress ACL and deep packet classification fully offloaded to line card NPUs, eliminating RSP CPU load even with hundreds of thousands of unique subscriber access control policies active simultaneously.
3. Wire-Speed Multi-Service Hardware Offloading
   Hardware accelerated wire-speed processing for MPLS label switching, MPLS Traffic Engineering (TE), Layer 2 VPNs (VPLS, EoMPLS), Layer 3 VPNs, NAT44/NAT64/CGNAT large-scale carrier-grade network address translation, IPsec VPN encryption/decryption, multicast packet replication, MACsec link-layer encryption, EVPN-VXLAN tunnel termination, Segment Routing SRv6, integrated OTN mapping support, and NetFlow v9/IPFIX traffic recording.
4. High-Density Carrier Ethernet Flow Point (EFP) Capacity
   Supports up to 64,000 independent EFPs for large-scale BNG subscriber termination and multi-service access edge deployments, significantly higher than the 16,000 EFP limit of transport-focused -TR line cards optimized for pure backbone transmission.
5. Unified Forwarding Table Scale (Shared with TR Variants)
   Consistent high-capacity forwarding table resources across all 32-port 100GE 5th-gen line card variants: 4 million IPv4 FIB routes, 2 million IPv6 FIB routes, 2 million MAC address table entries, and support for up to 8,000 independent Layer 3 VRF routing instances for multi-tenant service deployments.

5. Carrier-Grade High Availability (HA) Feature Set

1. OIR Online Insertion and Removal
   Full hot-swap capability; the line card can be inserted, removed, or replaced without chassis power cycling, RSP reboot, or live traffic interruption on other installed line cards within the chassis.
2. Independent Hardware Fault Isolation
   Separate dedicated power supply, clock distribution, and forwarding plane for each line card; hardware faults on individual ports or the entire line card cannot propagate to other line cards or chassis Route Switch Processors (RSPs).
3. Full Chassis Redundancy Compatibility
   Seamless interoperability with all ASR 9900 chassis redundant components: 1+1 redundant RSP5-X control processors, N+1 redundant power supplies, and redundant fan tray assemblies, enabling end-to-end five-nines (99.999%) annual carrier-grade service availability.
4. ISSU In-Service Software Upgrade
   Supports non-disruptive IOS XR firmware image upgrades for the line card without terminating active BNG subscriber sessions, IPTV video streams, mobile backhaul links, or live MPLS backbone traffic flows.
5. Synchronous Timing Support
   Integrated SyncE and IEEE 1588-2008 PTP precision timing hardware for mobile 5G transport and broadcast video deployments, with support for BITS, GPS ToD, 1-PPS and 10MHz timing interfaces.

7. Front Panel LED Indicator System

1. Global Line Card STATUS LED: Displays line card power supply status, boot initialization progress, and critical hardware fault alarm notifications.
2. Per-Port Dual-Color LED Indicators (32 QSFP28 ports):
   • Off: QSFP28 transceiver absent, port administratively shut down, or optical signal loss (LOS) detected
   • Solid Amber: Link established with active Layer 1 optical alarms (excessive bit error rate BER, loss of frame LOF)
   • Solid Green: Stable, error-free active 100GE/40GE breakout link
   • Blinking Green: Bidirectional data packet traffic transmitting/receiving on the port

8. Key Deployment Advantages

1. Service Edge Optimized Hardware Architecture for Large-Scale Subscriber Aggregation
   The SE variant’s massively expanded QoS, policer, EFP, NAT and MACsec hardware resources eliminate RSP CPU bottlenecks in BNG, multi-service PE, and broadband access edge deployments, delivering superior concurrent subscriber session scale compared to transport-focused -TR line cards with limited service processing resources.
2. Ultra-High-Density 32-Port Wire-Speed 100GE QSFP28 Interfaces
   Thirty-two independent QSFP28 100GE interfaces deliver industry-leading high 100G uplink density for access aggregation, mobile edge, carrier Ethernet, IPTV, and DCI deployments, minimizing total chassis slot consumption to reduce overall hardware CapEx. Broad QSFP28 transceiver compatibility supports flexible fiber reach selection for varied aggregation and core link distances, plus breakout capability to replace dozens of 10GE links with a single 100G port.
3. Unified Layer 2 / Layer 3 Multi-Service Convergence
   A single line card simultaneously supports Layer 2 carrier Ethernet switching and Layer 3 MPLS backbone routing services, allowing network operators to consolidate broadband subscriber aggregation, video delivery, and mobile transport workloads onto a single ASR 9900 chassis to lower daily operational OpEx overhead.
4. Complete Carrier-Grade High Availability Toolkit
   Native OIR hot swap, ISSU non-disruptive firmware upgrades, hardware fault isolation, and full chassis redundant component compatibility deliver uninterrupted service for mission-critical subscriber-facing edge networks with strict high-uptime operational requirements.
5. Broad Transceiver & Chassis Investment Protection
   Fully compatible with the complete Cisco QSFP28 100G/40G optical transceiver portfolio, and all modern ASR 9900 series chassis models, enabling flexible network capacity expansion and full investment protection for existing ASR 9900 router deployments.
