About the Cisco ASR 9000 A9K-MPA-20X1GE Cisco ASR 9000 carrier router
The Cisco ASR 9000 A9K-MPA-20X1GE is managed via on-box CLI through Cisco IOS XR with no separate licensing requirement for basic forwarding operations, making it a straightforward deployment choice for enterprises seeking modular, scalable carrier-class routing without complex controller dependencies.
This Modular Port Adapter delivers 20 SFP-based 1GE ports, each supporting 1000 Mbps throughput, with compatibility across 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-T, and 1000BASE-BX transceiver types. The A9K-MPA-20X1GE slots into Cisco ASR 9000 line cards equipped with MPA slots—including the A9K-MOD80-SE, A9K-MOD160-SE, and A9K-MOD400-CM—enabling rapid port density expansion within existing chassis investments. Layer 2 switching intelligence includes 802.1Q VLAN, 802.1ad Q-in-Q, Ethernet OAM (802.3ah/802.1ag), and LACP (802.3ad) link aggregation. Layer 3 routing encompasses full IPv4, IPv6, MPLS, and L3 VPN (VRF) support, with dynamic routing protocols including OSPF, IS-IS, and BGP. QoS functionality integrates hierarchical traffic shaping, policing, and scheduling to prioritize mission-critical flows. High availability is reinforced through Non-stop Forwarding (NSF), Graceful Restart, and BFD-based fast failure detection, while multicast support spans PIM SSM, PIM SM, IGMP, and MLD. CE, FCC Class A, and UL certifications confirm regulatory alignment.
Network engineers and IT procurement teams managing carrier-grade service provider or large enterprise WAN infrastructure rely on this adapter to scale distributed access layers without swapping chassis. The modular design reduces operational complexity and total cost of ownership by maximizing existing ASR 9000 platform investments.
