Cisco 3550 Series

Intelligent Ethernet Switches

The Cisco Catalyst 3550 Series Intelligent Ethernet Switch is a line of stackable, multilayer switches that provide high availability, quality of service (QoS), and security to enhance network operations. With a range of Fast Ethernet and Gigabit Ethernet configurations, the Cisco Catalyst 3550 Series is a powerful option for enterprise and metro access applications.

Customers can deploy industry-leading intelligent services, such as advanced quality of service (QoS), rate-limiting, Cisco security access control lists, multicast management, and high-performance IP routing--while maintaining the simplicity of traditional LAN switching. Embedded in the Catalyst 3550 Series is the Cisco Cluster Management Suite (CMS) Software, which allows users to simultaneously configure and troubleshoot multiple Catalyst desktop switches using a standard Web browser. Cisco CMS Software provides new configuration wizards that greatly simplify the implementation of converged applications and network-wide services.

The Cisco Catalyst 3550 Series Intelligent Ethernet Switches include the following configurations:

• Catalyst 3550-24 Switch—24 10/100 ports and two Gigabit Interface Converter (GBIC)-based Gigabit Ethernet ports; 1 rack unit (RU)
• Catalyst 3550-24 PWR Switch—24 10/100 ports with integrated inline power and two GBIC-based Gigabit Ethernet ports; 1 RU
• Catalyst 3550-24-DC Switch—24 10/100 ports and two GBIC-based Gigabit Ethernet ports; 1 RU; DC-powered
• Catalyst 3550-24-FX Switch—24 100FX ports and two GBIC-based Gigabit Ethernet ports; 1 RU
• Catalyst 3550-48 Switch—48 10/100 ports and two GBIC-based Gigabit Ethernet ports; 1 RU
• Catalyst 3550-12G Switch—10 GBIC-based Gigabit Ethernet ports and two 10/100/1000BASE-T ports; 1.5 RU
• Catalyst 3550-12T switch—10 10/100/1000BASE-T ports and two GBIC-based Gigabit Ethernet ports; 1.5 RU

The built-in Gigabit Ethernet ports accommodate a range of GBIC transceivers, including the Cisco GigaStack® GBIC, 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX and CWDM GBICs. The dual GBIC-based Gigabit Ethernet implementation on the Fast Ethernet configurations provides customers tremendous deployment flexibility—allowing customers to implement one type of stacking and uplink configuration today, while preserving the option to migrate that configuration in the future. High levels of stack resiliency can also be implemented by deploying dual redundant Gigabit Ethernet uplinks, a redundant GigaStack GBIC loopback cable, UplinkFast and CrossStack UplinkFast technologies for high-speed uplink and stack interconnection failover, and Per VLAN Spanning Tree Plus (PVST+) for uplink load balancing. This Gigabit Ethernet flexibility makes the Catalyst 3550 switches an ideal LAN edge complement to the Cisco Catalyst 6500 family of Gigabit Ethernet optimized core LAN switches.

Included with the Catalyst 3550-24, 3550-24 PWR, 3550-24-DC, 3550-24-FX and 3550-48 are the Standard Multilayer Software Image (SMI) or the Enhanced Multilayer Software Image (EMI). The SMI feature set includes advanced QoS, rate-limiting, access control lists (ACLs), and basic static and routed information protocol (RIP) routing functionality. The EMI provides a richer set of enterprise-class features including advanced hardware-based IP unicast and multicast routing and the Web Cache Communication Protocol (WCCP). After initial deployment, the EMI Upgrade Kit gives users the flexibility to upgrade to the EMI. The Catalyst 3550-12T and 3550-12G are only available with the EMI.
