SA-VAM2+ Overview
The VPN Acceleration Module 2+ (SA-VAM2+) is a single-width port adapter (see
Figure 1-1
)
supported on the Cisco 7204VXR and Cisco 7206VXR routers with the NPE-225, NPE-400, the
NPE-G1 or NPE-G2 processor, and the Cisco 7301 router.
SA-VAM2+ features 128/192/256-bit Advanced Encryption Standard (AES) in hardware, Data Encryption
Standard (DES), Triple DES (3DES), and IPv6 IPSec, providing increased performance for site-to-site
and remote-access IPSec VPN services. The Cisco SA-VAM2+ provides hardware-assisted Layer 3
compression services with its encryption services, conserving bandwidth and lowering network
connection costs over secured links, as well as full Layer 3 routing, quality of service (QoS), multicast
and multiprotocol traffic, and broad support of integrated LAN/WAN media.
The SA-VAM2+ can be installed directly in the port adapter slots (see
Figure 1-5
) of the Cisco 7000VXR
series routers and the Cisco 7301 router. Alternatively, you can install the SA-VAM2+ into a Port
Adapter Jacket Card (product ID:C7200-JC-PA) that is inserted in the I/O controller slot of a
Cisco 7200VXR router with an NPE-G1 or NPE-G2 processor, for additional bandwidth (see
Figure 1-2
).
The SA-VAM2+ support in the Port Adapter Jacket Card allows you to take advantage of the increase in
NPE-G1 or NPE-G2 performance, while maintaining VPN performance. You allow more bandwidth to
the regular port adapter slots when you install the SA-VAM2+ in the Port Adapter Jacket Card. See the
Port Adapter Jacket Card Installation Guide
for more information.
