High-Performance IP Routing
The Cisco Catalyst 3550 Intelligent Ethernet Switch is a enterprise-class, stackable, multilayer switches that provide high availability, scalability, security and control to enhance the operation of the network. With a range of Fast Ethernet and Gigabit Ethernet configurations, the Catalyst 3550 can serve as both a powerful access layer switch for medium enterprise wiring closets and as a backbone switch for mid-sized networks. For the first time, customers can deploy network-wide 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 built-in Gigabit Ethernet ports in this switch accommodates a range of GBIC transceivers, including the Cisco GigaStack GBIC, 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, and 1000BASE-ZX 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 switch an ideal LAN edge complement to the Cisco Catalyst 6500 Family of Gigabit Ethernet optimized core LAN switches.
Features and Benefits:
Cisco UplinkFast/BackboneFast technologies ensure quick fail-over recovery enhancing overall network stability and reliability
CrossStack UplinkFast (CSUF) technology provides increased redundancy and network resiliency through fast spanning-tree convergence (less than two seconds) across a stack of switches using GigaStack(TM) GBICs in an independent stack backplane cascaded configuration.
Supports Cisco Hot Standby Router Protocol (HSRP) to create redundant failsafe routing topologies-requires Enhanced Multilayer Software Image (EMI).
Redundant stacking connections provide support for a redundant loopback connection for top and bottom switches in an independent stack backplane cascaded configuration.
Command switch redundancy enabled in the Cisco Cluster Management Suite (CMS) Software allows customers to designate a backup command switch that takes over cluster management functions if the primary command switch fails.
Provides unidirectional link detection (UDLD) for detecting and disabling unidirectional links on fiber-optic interfaces caused by incorrect fiber-optic wiring or port faults
Support for Cisco`s optional Redundant Power System 300 (RPS 300) that provides superior internal power source redundancy for up to six Cisco networking devices resulting in improved fault tolerance and network uptime
