Catalyst 2900

Product Overview

Cisco Systems' standalone Catalyst 2900 switch combines high-speed configuration flexibility with exceptional affordability for workgroup applications. Available for a very low cost per port, the Catalyst 2900 is ideal for Ethernet workgroups and individual users requiring increased performance and 100BaseT or 100BaseF connectivity to servers and backbones.

The Catalyst 2900 is part of Cisco's Catalyst family, a comprehensive line of high-performance switches designed to help you easily migrate from traditional shared LANs to fully switched networks. An integral element of the CiscoFusion scalable architecture, the Catalyst family delivers the varying levels of flexibility and cost-effectiveness required for today's desktop, workgroup, and backbone applications while enabling enterprise-wide switched internetworks.

The Catalyst 2900 switch supports up to 16,000 MAC addresses, has 14 Fast Ethernet ports in a fixed configuration of either 10/100BaseTX or 100BaseFX, and can be used to deploy 100-Mbps Fast Ethernet connections to existing LAN segments or high-performance workstations and servers.

Standard Features

The Catalyst 2900 switch supports the following standard features:

• 14-port fixed configuration chassis, which includes a single power supply
  

• Supervisor Engine:
  

  • High-performance, low latency 1.2-Gbps switching backplane with tri-level priority
    

  • Hardware-based support for static entries and self-learning of the 16,000 active MAC addresses and associated VLANs in the bridge lookup table
    

  • 25-MHz 68EC040 network management processor
    

  • Two Fast Ethernet interfaces (full or half-duplex), which can be ISL trunks
    

  • Fully integrated support for 1024 VLANs
    

  • Console port (female DCE EIA/TIA-232)
    

  • 8-MB DRAM
    

  • 4-MB Flash EPROM for downloadable microcode and software upgrades
    

  • 256-KB NVRAM
    

  • 192-KB input buffers per interface
    

  • Self-diagnostics at startup and runtime
    

  • Environmental monitoring
    

• VLAN ISL support
  

  • Virtual Trunking Protocol (VTP) for distributing VLAN configuration information
    

  • Virtual Trunking Protocol MIB
    

  • Dynamic ISL Protocol providing SNMP instrumentation for VTP
    

• Embedded RMON: provides the following four RMON groups: statistics, history, alarms, events
  

• Switched port analyzer functionality: allows monitoring of a single port or VLAN via a single monitor port. Segment traffic is "mirrored" to a user-designated port
  

• Load sharing via spanning-tree priority on a per-VLAN basis on ISL trunks between Catalyst 2900 and Catalyst 5000s; multiple ports can be used to achieve 800 Mbps and above
  

• 10/100 Fast Ethernet interface with autosensing speed detection for easy upgrade
  

• Standards-compliant Fast Ethernet interfaces for 100BaseTX and 100BaseFX
  

• AC power supply
  

• Power cord
  

• Rack-mounting hardware
  

• Cable management system
