VSA Overview

Note The C7200 VSA is only supported on the Cisco 7200VXR with the NPE-G2 processor.

The VSA features hardware acceleration for Advanced Encryption Standard (AES), Data Encryption Standard (DES), and Triple DES (3DES), providing increased performance for site-to-site and remote-access IPSec VPN services. The Cisco C7200 VSA solution provides quality of service (QoS), multicast and multiprotocol traffic, and broad support of integrated LAN/WAN media.
