Service Adapters (SA)

Provide specialized network services on a 7200 or on a VIP or VIP2 card, as follows:

CSA (Compression Service Adapter)

ESA (Encryption Service Adapter)

ISA (Integrated Service Port Adapter)

VAM (VPN Acceleration Module)

 


Compression Service Adapter (CSA)

Provides compression and decompression services (in hardware) for multiple applications concurrently. Can interface with routers that only support software compression. In addition to compression algorithms in use for software compression (Stac compression and Novell Predictor), it supports Magnalink Scalable Algorithm (MSA) and IBM Advanced Loss Data Compression (ALDC).

CiscoView can be used to monitor:

Compression statistics

CSA configuration information

There are three LEDs on the Compression Service Adapter:

LED

Meaning if Lit (Green)

Enabled

The CSA card is enabled.

Compression Enabled

Compression is enabled.

Error

Not currently supported.


ISA Port Adapter

The ISA Port adapter provides high-performance, hardware-assisted tunneling and encryption services for VPN remote access and site-to-site intranet and extranet applications. ISA supports both IPSec or Point-to-Point Tunneling Protocol/Microsoft Point-to-point Encryption (PPTP/MPPE).

SM-ISM

Hardware accelerator for IPSEC encryption and compression, and MPPE encryption.

SM-ISM is used only in slot 5 of the 7100 series.

SA-ISA

Hardware accelerator for IPSEC encryption and compression, and MPPE encryption.

May not be used in slot 5 of the 7100.

 


Encryption Service Adapter (ESA)

The Encryption Service Adapter (ESA) provides hardware-assisted 40/56-bit DES encryption services at 30 Mbs for Cisco 7200 series and 7500 series routers.

7200 Series

Install in any PA slot. Provides encryption services for all supported port adapters in the chassis.

7500 Series

Install in one PA slot of a VIP card (VIP2-40 or later). Provides encryption services for a supported port adapter in the adjacent slot.

Software encryption information is also available for devices that support it.

The ESA has an Enabled LED. You may have to upgrade to a more recent release of IOS if a card is unknown or unsupported.


VAM (VPN Acceleration Module)

The VPN Acceleration Module (VAM) for Cisco 7200 and 7100 Series routers provides high-performance, hardware-assisted encryption, key generation, and compression services suitable for site-to-site virtual private network (VPN) applications.

The VAM supports Data Encryption Standard (DES) or Triple DES (3DES) IPsec encryption at greater than full-duplex DS-3 line rate (up to 145 Mbps) for site-to-site VPNs such as intranets and extranets. Moreover, it supports up to 5000 encrypted tunnels for mixed VPN environments that have both site-to-site and remote access VPN requirements. The VAM also integrates hardware-assisted RSA and IPPCP Layer 3 compression. Accelerating RSA processing speeds tunnel setup and creation time improving overall VPN initialization. And in those environments where bandwidth is costly, the VAM provides hardware-based IP Payload Compression Protocol (IPPCP) Lempel-Ziv-Stac (LZS) processing to compress network traffic before it is encrypted and sent over pay-per-byte WAN connections.

The VPN Acceleration Module II (VAM2) for Cisco7200 series provides high performance IPsec VPN, Advanced Encryption Standards(AES), large VPN scalability and hardware accelerated IPPCP compression.

SM-VAM

SM-VAM, installs in the service module slot on Cisco 7100 Series routers.

SA-VAM

SA-VAM, installs in port adapter slot on Cisco 7200 or 7100 Series routers.

SA- VAM2

SA-VAM2, installs in port adapter slot on Cisco 7200


Unknown Card

A card that is unknown to the Cisco IOS image in the router and to the currently installed CiscoView package. The Cisco Connection Online (CCO) at http://www.cisco.com has information about upgrading the IOS image or the CiscoView package.


Unsupported Card

A card that CiscoView recognizes but does not yet support. The Cisco Connection Online (CCO) at http://www.cisco.com has information about upgrading your CiscoView package.
