CSM modul

The Cisco Content Switching Module (CSM) adds advanced layer 4 to layer 7 content switching capabilities to the Cisco Catalyst 6500 Series Switch or the Cisco 7600 Series Router providing high-performance, feature rich layer 4 to layer 7 load balancing to existing layer 2 and layer 3 features of the Catalyst platforms. The Cisco CSM offers a complete set of advanced features and benefits including:

• Investment protection in a high-density, scalable platform with proven reliability
• Reduced application response times, optimized service delivery, increased application uptime and service scalability for servers, firewalls, VPN devices, SSL termination devices and caches
• Fault-tolerant configurations to provide improved application uptime utilizing connection and sticky state redundancy for seamless failover
• Accommodation for a wide range of common IP protocols, including TCP, User Datagram Protocol (UDP), and higher-level protocols, including Hypertext Transfer Protocol (HTTP), File Transfer Protocol (FTP), Telnet, Domain Name System (DNS), Real-Time Streaming *Protocol (RTSP) and Simple Mail Transfer Protocol (SMTP)
• Integration into an existing infrastructure, minimizing the time and resources required to deploy content switching services

MSFC

Multilayer switching feature card (MSFC)—The MSFC is essentially a Cisco IOS router based upon the high-performance 7200 series router. This provides the route processor functions required by the PFC to implement L3 switching. The MSFC provides the necessary routing information in the PFC route cache so that the PFC can L3 switch packets.
