Cisco Catalyst 3550 Series Intelligent Ethernet Switches
Chapter 2 LAN Switching
Key Features
• Network control and bandwidth optimization via advanced Quality of Service (QoS),
granular rate-limiting, Access Control Lists (ACLs), and multicast services
• Network security through a wide range of authentication methods, data encryption
technologies, and access restriction features based on users, ports, and MAC addresses
• Network scalability through advanced routing protocols such as EIGRP, OSPF, BGP,
and PIM (requires Enhanced Multilayer Software Image (EMI))
• Intelligent adaptability through Cisco Identity Based Networking Services (IBNS)
offering greater flexibility and mobility to stratified users
• Lower Total Cost of Ownership (TCO) for IP Telephony and Wireless LAN
deployments through integrated inline power (Catalyst 3550-24 PWR only)
• Easy switch configuration and deployment of advanced services through the embedded
Cluster Management Suite (CMS) Software
• Stackable up to 9 switches with the Gigastack GBIC
