 SA-VAM, Cisco SA-VAM, VPN Acceleration Module (VAM) for Cisco 7200 and 7100 Series
The VAM supports LAN/WAN media and full Layer 3 routing services. VAMs provide hardware-assisted tunneling and encryption services for virtual private network (VPN) remote access, site-to-site intranet and extranet applications, including security, quality of service (QoS), firewall and intrusion detection, and service-level validation and management. The VAM off-loads IPSec processing from the main processor to permit resources on the processor engines for other tasks.
The VAM provides hardware-accelerated support for multiple encryption functions:
•56-bit Data Encryption Standard (DES) standard mode: Cipher Block Chaining (CBC)
•3-Key Triple DES (168-bit)
•Secure Hash Algorithm (SHA)-1 and Message Digest 5 (MD5) hash algorithms
•Rivest, Shamir, Adelman (RSA) public-key algorithm
•Diffie-Hellman key exchange RC4-40
The VAM is available as a service adapter (SA-VAM), and as a service module (SM-VAM). The SA-VAM is supported on the Cisco 7100 series routers, the Cisco 7200 series routers, and the Cisco 7401ASR router. The SM-VAM is supported on the Cisco 7100 series router. |
