Outstanding Performance
12 or 24 10BaseT/100BaseTX autosensing ports deliver performance where it is needed most---to demanding workgroups and servers---while preserving legacy 10BaseT connectivity (Catalyst 2912 XL and Catalyst 2924 XL).
Twenty-two 10BaseT/100BaseTX autosensing ports deliver performance where it is needed most---to demanding workgroups and servers---while preserving legacy 10BaseT connectivity. Two 100BaseFX ports deliver up to 200 Mbps of bandwidth over an extended distance of up to 2 kilometers (Catalyst 2924C XL).
A 3.2-Gbps switching fabric and 3.0-million-pps forwarding rate ensure optimal performance on all 10BaseT/100BaseTX ports.
Full-duplex operation on switched 100BaseT ports delivers up to 200 Mbps of bandwidth to end stations, servers, and between switches.
A 4-MB shared-memory architecture ensures the highest possible throughput by eliminating head-of-line blocking, minimizing packet loss, and reducing congestion from multicast and broadcast traffic.
Bandwidth aggregation through Fast EtherChannel technology enhances fault tolerance and offers up to 800 Mbps of bandwidth among switches, routers, and individual servers.
Up to 12 Fast EtherChannel bandwidth aggregation groups per switch allow each Catalyst 2900 XL switch to aggregate multiple network devices via standard, full-duplex 10/100 Fast EtherChannel links.
CGMP enables a switch to selectively and dynamically forward routed IP multicast traffic to targeted multimedia end stations, reducing overall network traffic.
A configurable network port supports unlimited Media-Access-Control (MAC) addresses for backbone connectivity.
Ease of Use and Ease of Deployment
Cisco Switch Clustering technology allows a user to manage up to 16 interconnected Catalyst 2900 XL, 3500 XL, and 1900 switches through a single IP address, regardless of location.
CVSM software, a Web-based interface, provides network and stack views of a group of Catalyst 2900 XL switches from any node on the Internet with a Web browser.
Autosensing on each port detects the speed of the attached device and automatically configures the port for 10- or 100-Mbps operation, easing the deployment of the switch in mixed 10BaseT and 100BaseT environments.
Autonegotiation on all 10/100 ports automatically selects half- or full-duplex transmission mode to optimize bandwidth.
Default configuration stored in flash memory ensures that the switch can be connected to the network and pass traffic with minimal user intervention, and preserves configuration in case of power outages.
Integrated Cisco IOS Switching Software
CGMP Fast Leave software allows end stations to quickly exit from a multicast session, reducing superfluous traffic on the network.
Bandwidth aggregation through Fast EtherChannel technology enhances fault tolerance and offers up to 800 Mbps of bandwidth between switches, routers, and individual servers.
Per-port broadcast storm control prevents faulty end stations from degrading overall systems performance with broadcast storms.
Command-line interface (CLI) support provides common user interface and a command set with Catalyst 5000, 5500, and 8500 series switches and all Cisco routers.
Comprehensive Manageability
Simple Network Management Protocol (SNMP) and Telnet interface support delivers comprehensive in-band management, and the Cisco IOS CLI-based management console provides detailed out-of-band management.
CVSM, a built-in Hypertext Transfer Protocol (HTTP) server, provides an ease-of-use Web-based management interface through a standard browser such as Netscape Navigator or Microsoft Explorer.
The switch is manageable through CiscoWorks Windows and CiscoWorks2000 network management software on a per-port and per-switch basis, providing a common management interface for Cisco routers, switches, and hubs.
Cisco Discovery Protocol (CDP) enables a CiscoWorks network management station to automatically discover the switch in a network topology.
An embedded Remote Monitoring (RMON) software agent supports four RMON groups (history, statistics, alarms, and events) for enhanced traffic management, monitoring, and analysis.
Cisco IOS software supports all nine RMON groups through use of a Switched Port Analyzer (SPAN) port, which permits high-performance traffic monitoring of a single port, a group of ports, or the entire switch from a single network analyzer or RMON probe.
Auto-configuration eases deployment of switches in the network by automatically configuring multiple switches across a network via a boot server.
Trivial File Transfer Protocol (TFTP) reduces the cost of administering software upgrades by enabling downloads from a centralized location.
Each port includes a LED for port status, half duplex/full duplex, and 10BaseT/100BaseT indications as well as switch-level status LEDs for system, module status, redundant power supply (RPS), and bandwidth utilization, providing a comprehensive and convenient visual management system.
Security and Redundancy
IEEE 802.1D Spanning-Tree Protocol support for redundant backbone connections and loop-free networks simplifies network configuration and improves fault tolerance.
MAC-based, port-level security prevents unauthorized stations from accessing a switch.
User-selectable address learning mode simplifies configuration and enhances security.
Support for the optional Cisco 600-watt redundant AC power system provides a backup power source for up to four units for improved fault tolerance and network uptime.
Multilevel security on the console access prevents unauthorized users from altering the switch configuration.
