Cisco ASR 1000 Series SPA Interface Processor 40G - expansion module

The Cisco ASR 1000 Series 10-N-Gbps ESP (ASR1000-ESP10-N) is the nonencryption version of the Cisco ASR 1000 Series 10-Gbps ESP (ASR1000-ESP10). The Cisco ASR 1000 Series 10-N-Gbps ESP can only support noncrypto Cisco IOS Software images and will never support encryption capabilities such as IP Security (IPsec). In future releases, the Cisco ASR 1000 Series 10-N-Gbps ESP may support secured network management features such as Secure Shell (SSH) Protocol, Secure Sockets Layer (SSL), and Simple Network Management Protocol Version 3 (SNMPv3). - The Cisco ASR 1000 Series ESPs are responsible for the data-plane processing tasks, and all network traffic flows through them. The modules perform all baseline packet routing operations, including MAC classification, Layer 2 and Layer 3 forwarding, quality-of-service (QoS) classification, policing and shaping, security access control lists (ACLs), VPNs, load balancing, and NetFlow. They are also responsible for features such as firewalls, intrusion prevention, Network Based Application Recognition (NBAR), Network Address Translation (NAT), and Cisco IOS Flexible Pattern Matching.
