Cisco Catalyst 3550-24 Switch

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.

Features:

• 24 10/100 ports and 2 GBIC-based Gigabit Ethernet ports.
• 1 RU stackable, multilayer switch.
• Delivers enterprise-class intelligent services to the network edge.
• Standard Multilayer Software Image (SMI) installed, upgradeable to full dynamic IP routing.
• IEEE 802.1x (planned future software support) for dynamic port-based security.
• Cisco security VLAN ACLs (VACLs) on all VLANs to prevent unauthorized data flows to be bridged within VLANs.
• Time-based ACLs allow the implementation of security settings during specific periods of the day.
• Private VLAN edge provides security and isolation between ports on a switch, ensuring that voice traffic travels directly from its entry point to the aggregation device through a virtual path and cannot be directed to a different port.
• TACACS+ and RADIUS (planned future software support) authentication to enable centralized control of the switch and restrict unauthorized users from altering the configuration.
• MAC-based port-level security prevents unauthorized stations from accessing the switch (planned future software support).
• Multilevel security on console access prevents unauthorized users from altering the switch configuration.
• The user-selectable address-learning mode simplifies configuration and enhances security.
• Bridge protocol data unit (BPDU) guard shuts down Spanning-Tree Protocol PortFast-enabled interfaces when BPDUs are received to avoid accidental topology loops.
• Spanning-tree root guard (STRG) prevents edge devices not in the network administrator's control from becoming Spanning-Tree Protocol root nodes.
