QUALITY OF SERVICE
• User Monitoring and Profiling-Gain detailed understanding of user utilization of network and application resources. This information can then be used to efficiently plan and allocate resources.
• Application Monitoring and Profiling-Gain a detailed view of application traffic patterns over the network. For example, the network administrator can see the percentage of traffic used by the Web, File Transfer Protocol (FTP), Telnet, and other well-known TCP/IP applications.
• Network Monitoring-Enables network monitoring capabilities. RMON, RMON2, and flow-based analysis techniques can be used to provide proactive problem detection, efficient troubleshooting, and rapid problem resolution.
• Network Planning-Provides key information for sophisticated tools such as those from the Cisco Netsys application to optimize strategic network planning.
• Accounting and Billing-Provides metering (for example, flow data, including details such as IP addresses, packet and byte counts, time stamps, application ports) for flexible resource utilization accounting.
MORE ADVANCED SERVICES
• Protocol Filtering-On a port-by-port basis, the NFFC II can filter broadcast traffic by protocol, resulting in more efficient use of bandwidth for end stations. For example, IP-only workstations will not receive broadcasts from "chatty" protocols such as IPX Service Advertisement Protocol (SAPs), and RIPS. In addition, protocol filtering is automatically set up by system software so that there is no configuration overhead for the network manager.
• IGMP Snooping-User stations request multicast applications by sending IGMP messages. With an NFFC II, Catalyst switches are able to act upon these user-station IGMP messages with a feature called IGMP snooping. By receiving and reading IGMP messages, Catalyst switches become intelligent multicast devices and forward only multicast streams to the appropriate user end stations.
• Efficient Multicast-With a future software upgrade, the NFFC II provides hardware-based duplication of IP multicast packets destined for multiple subnets. This feature offloads the software-based router from duplicating and transmitting multicast packets.
