Feature Benefit
• Bandwidth aggregation up to 800 Mbps through Cisco Fast EtherChannel
®
technology enhances fault
tolerance and offers higher-speed aggregated bandwidth between switches and to routers and
individual servers.
Multicast
Efficient Multicast Distribution • Multicast VLAN Registration provides efficient multicast distribution in ring networks by dedicating a
single VLAN for multicast traffic, thereby removing duplicate multicast traffic in other VLANs.
• Internet Group Management Protocol (IGMP) Snooping helps enable intelligent management of
multicast traffic by examining IGMP messages.
Robust Multicast Control • IGMP Fast Leave provides a fast channel-changing capability for IPTV services.
• IGMP filtering provides control of groups each user can access.
• IGMP Throttling controls the maximum number of multicast groups each user can access.
QoS and Control
Advanced QoS • The Cisco Modular QoS CLI (MQC) provides a modular and highly extensible framework for deploying
QoS, by standardizing the CLI and semantics for QoS features across all platforms that are supported
by Cisco IOS Software.
• Standard 802.1p class of service (CoS) and differentiated services code point (DSCP) field
classification are provided, using marking and reclassification on a per-packet basis by source and
destination IP address, source and destination MAC address, or Layer 4 TCP/User Datagram Protocol
(TCP/UDP) port number.
• Cisco control-plane and data-plane QoS ACLs on all ports help ensure proper marking on a per-packet
basis.
• Shaped Round Robin (SRR) scheduling helps ensure differential prioritization of packet flows by
intelligently servicing the ingress and egress queues.
• Weighted Tail Drop (WTD) provides congestion avoidance at the ingress and egress queues before a
disruption occurs.
• Strict priority queuing helps ensure the highest-priority packets are serviced ahead of all other traffic.
• Priority queue rate limiting provides optional protection against queue starvation.
• There is no performance penalty for advanced QoS functionalities.
Granular Rate Limiting • The Cisco Committed Information Rate (CIR) function provides bandwidth in increments as low as 8
kbps.
• Ingress policing is provided based on source and destination IP address, source and destination MAC
address, Layer 4 TCP/UDP information, or any combination of these fields, using QoS ACLs (IP ACLs
or MAC ACLs), class maps, and policy maps.
• Asynchronous data flows upstream and downstream from the end station or on the uplink are easily
managed using ingress policing and egress shaping.
• Egress shaping for each queue provides smooth traffic control of available bandwidth.
• Egress port rate limiting allows the service provider to control the traffic rate that is transmitted out of
the port.
Network Security
Complete Security Solutions Subscriber Security
• IEEE 802.1x allows dynamic, port-based security by providing user authentication.
• IEEE 802.1x with VLAN assignment allows a dynamic VLAN assignment for a specific user regardless
of where the user is connected.
• IEEE 802.1x and port security are provided to authenticate the port and manage network access for all
MAC addresses.
• No local switching behavior provides security and isolation between UNIs, helping ensure that users
cannot monitor or access other users’ traffic on the same switch.
• DHCP Snooping prevents malicious users from spoofing a DHCP server and sending out bogus
