Note - Requires XFPs for 10GE, SFPs for GE
The Cisco A9K-2T20GE-E High Queue Combo Line Card is a high-density Ethernet line card designed for Cisco ASR 9000 Series Aggregation Services Routers, providing flexible connectivity for service provider and enterprise WAN networks. It combines 2 × 10 Gigabit Ethernet XFP ports with 20 × Gigabit Ethernet SFP ports for scalable optical connectivity across edge routing, aggregation, and Carrier Ethernet environments. Its High Queue/Extended architecture provides enhanced traffic-management scalability for demanding network services.
Built for wire-speed Layer 2 and Layer 3 forwarding, the A9K-2T20GE-E supports IP/MPLS, Carrier Ethernet, VLAN services, Ethernet Flow Points (EFPs), and advanced Quality of Service (QoS). The line card provides high-scale queue and policer capabilities for bandwidth-intensive and latency-sensitive applications, while support for G.709, Forward Error Correction (FEC), frequency synchronization, and Synchronous Ethernet (SyncE) on compatible configurations provides additional flexibility for carrier-grade deployments.
Running Cisco IOS XR, the Cisco A9K-2T20GE-E integrates with the resilient architecture of ASR 9000 routers and supports high-availability deployments. It is an ideal solution for service provider networks, IP/MPLS edge routing, Carrier Ethernet, metro Ethernet aggregation, enterprise WAN infrastructure, and high-capacity network expansion requiring scalable Ethernet connectivity and advanced traffic management.
