Description:
The Cisco A9K‑MPA‑1X40GE is a high‑performance 40 Gigabit Ethernet Modular Port Adapter (MPA) designed for deployment in Cisco ASR 9000 Series Aggregation Services Routers. Engineered for carrier‑grade core, edge, and aggregation networks, this modular port adapter delivers full‑line‑rate 40 Gbps throughput via a single QSFP+ 40G Ethernet interface and supports a broad range of Cisco‑qualified optics such as 40GBASE‑SR4, 40GBASE‑LR4, and direct attach/AOC options (optics sold separately). The module integrates seamlessly into MPA‑capable slots of ASR 9000 platforms, enabling advanced Layer 2 and Layer 3 forwarding under Cisco IOS XR software with support for IPv4/IPv6, MPLS, L2VPN/L3VPN, jumbo frames, QoS, and carrier transport features. Typical use cases include high‑bandwidth uplinks, backbone interconnects, and service provider edge aggregation.
