Feature Benefit
• Cisco control plane and data plane quality of service ACLs on all ports to ensure proper marking on a per packet
basis.
• Four egress queues per port supported in hardware to enable differentiated management of up to four types of traffic.
• WRR scheduling to ensure differential prioritization of packet flows by intelligently servicing the egress queues.
• WRED on all Gigabit Ethernet ports for avoidance of congestion at the egress queues before a disruption occurs.
• Strict priority queuing to guarantee that the highest priority packets will always get serviced ahead of all other traffic.
• No performance penalty for highly granular quality of service functionality.
Granular Rate-
Limiting
• CIR functionality allows bandwidth to be guaranteed in increments as low as 8 Kbps.
• Rate-limiting based on source/destination IP address, source/destination MAC address, or Layer 4 TCP/UDP
information or any combination of these fields using QoS ACLs (IP ACLs or MAC ACLs), class maps, and policy
maps.
• Per port, per VLAN ingress policing enables the rate-limiting of individual VLANs on trunk ports.
• Ability to easily manage data flows asynchronously upstream and downstream from the end station or on the uplink
via ingress and ingress policing.
• 8 aggregate or individual ingress policers and 8 aggregate egress policers on each 10/100 port.
• 128 aggregate or individual ingress policers and 8 aggregate egress policers on each Gigabit Ethernet port.
Manageability
Cluster
Management Suite
• Built-in Web-based Cisco CMS Software provides an easy- to-use Web-based management interface through a
standard Web browser.
• Cisco AVVID Wizards use just a few user inputs to automatically configure the switch to optimally handle different
types of traffic: voice, video, multicast, and/or high-priority data.
• A security wizard is provided to restrict unauthorized access to servers and networks, and restrict certain applications
on the network.
• Cisco CMS Software allows the user to manage up to 16 inter-connected Cisco Catalyst 3550, 2950, 3500 XL, 2900
XL, 2900 LRE XL, and 1900 switches through a single IP address, without the limitation of being physically located
in the same wiring closet. Full backward compatibility ensures any combination of the above switches can be
managed with a Cisco Catalyst 3550 switch.
• The cluster software upgrade feature allows the user to automatically upgrade the system software on a group of
Cisco Catalyst 3550, 2950, 3500 XL, 2900 XL, 2900 LRE XL, and 1900 switches.
• Cisco Cluster Management Suite Software has been extended to include multilayer feature configurations such as
Routing Protocols, ACLs, and QoS parameters.
• Clustering now supports member discovery and cluster creation across a single Catalyst 3550 routed hop, enabling
the entire LAN to be managed in a single web interface (and with a single IP address if desired).
• Cisco Cluster Management Suite Guide Mode assists users in the configuration of powerful advanced features by
providing step-by-step instructions.
• Cisco Cluster Management Suite provides enhanced online help for context-sensitive assistance.
• Easy-to-use graphical interface provides both a topology map and front panel view of the cluster.
• Multi-device and multi-port configuration capabilities allow network administrators to save time by configuring
features across multiple switches and ports simultaneously.
• One-click software upgrades can be performed across the entire cluster simultaneously, and configuration cloning
enables rapid deployment of networks.
• Ability to launch the web-based management for a Cisco Aironet Wireless Access Point by simply clicking on its
icon in the topology map.
• User-personalized interface allows users to modify polling intervals, table views, and other settings within CMS and
