Cisco A9K-40GE-E

The latest generation of carrier-focused ethernet line cards, the Cisco ASR 9000 Series delivers economical, scalable line-rate Ethernet and IP/Multiprotocol Label Switching edge services. This new Cisco series provides hierarchical quality of service and simultaneous support for both Layer 2 and Layer 3 services, with allowing operators to qualify and stock a single line card that can be deployed in any combination of Layer 2 and Layer 3 applications. With their synchronization circuitry and dedicated backplane timing traces for accessing the route switch?s Stratum-3 subsystem, the Cisco ASR 9000 Series Ethernet Line Cards provide standards-based line-interface functions for enabling transport-class network timing, network-synchronized services and applications. These line cards can also be configured for proactive protection if signal degradation is detected.

This is a 40-Port GE High Queue line card and requires SFP compatibility.
