Catalyst 2924M XL 10/100 Autosensing Fast Ethernet Switch
Catalyst 2912MF XL 100BaseFX Fast Ethernet Aggregator Switch

The Cisco Catalyst® 2924M XL 10/100 autosensing Fast Ethernet switch combines outstanding performance, ease of use, and from the leader in networking, integrated Cisco IOS® software. The Catalyst 2924M XL is a flexible, scalable, and affordable solution, ideal for aggregating Ethernet and Fast Ethernet workgroups and delivering dedicated 10 or 100 Mbps connectivity for individual users and servers with high-speed uplink modules, including Gigabit Ethernet and ATM, to connect to servers and LAN backbones.

The Catalyst 2924M XL switch, a member of the Catalyst 2900 Series XL family, contains 24 10Base-T/100Base-TX ports and two versatile module slots to provide unmatched expansion capabilities and high-speed connectivity. The modular design allows users to easily add 10Base-T/100Base-T, 100Base-FX, Gigabit Ethernet, or Asynchronous Transfer Mode (ATM) (OC-3) ports to increase port density and deliver high-speed uplinks. With the Gigabit Ethernet module, Catalyst 2924M XL switches can be stacked (up to nine switches) with the low-cost Cisco GigaStack gigabit interface controller (GBIC). The advanced Cisco architecture incorporates a switch fabric of 3.2 Gbps and a forwarding rate of 3.0 million packets per second (pps) to deliver wire-speed performance across all ports.

The Cisco Catalyst 2912MF XL Fast Ethernet switch combines outstanding performance, ease of use, and integrated Cisco IOS software from the leader in networking. The Catalyst 2912MF XL is a flexible, scalable, and affordable solution, ideal for aggregating Fast Ethernet workgroups over 100Base-FX connections in small and midsized campus environments.

The Catalyst 2912MF XL switch, a member of the Catalyst 2900 Series XL family, contains 12 100Base-FX ports and two versatile module slots to provide unmatched expansion capabilities and high-speed connectivity. The modular design allows users to easily add 10Base-T/100Base-T, 100Base-FX, Gigabit Ethernet, or ATM (OC-3) ports to increase port density and deliver high-speed uplinks. With the Gigabit Ethernet module, Catalyst 2912MF XL switches (as well as the Catalyst 2924M XL switch) can be stacked (up to nine switches) with the low-cost Cisco GigaStack GBIC. The advanced Cisco architecture incorporates a switch fabric of 3.2 Gbps and a forwarding rate of 3.0 million pps to deliver wire-speed performance across all ports. Flexible Stacking with the GigaStack GBIC

Gigabit Ethernet-enabled Catalyst 2900 Series XL switches and Catalyst 3500 Series XL can be stacked using the low-cost two-port Cisco GigaStack GBIC, which offers a range of highly flexible stacking and performance options. Customers can deploy a 1-Gbps independent stack backplane in a cascade configuration, or scale up to 5-Gbps of bandwidth in a star configuration using the Catalyst 3508G XL Gigabit Ethernet aggregation switch. Network managers may use one or both of the available GBIC ports on a Gigabit Ethernet-enabled Catalyst 2900 Series XL switch to create high-speed uplinks to the network core, using standard Gigabit Ethernet or Gigabit EtherChannel technology. High resiliency can also be implemented by deploying dual Gigabit Ethernet uplinks, a redundant GigaStack loopback cable, Cisco Uplink Fast and Cross-stack Uplink Fast technologies for high-speed uplink and stack interconnection failover, and PVST+ (Per VLAN Spanning Tree) for uplink load balancing. Cisco Switch Clustering

Breakthrough Cisco Switch Clustering technology enables up to 16 interconnected Catalyst 3500 XL, 2900 XL, and Catalyst 1900 switches, regardless of geographic proximity, to form a single IP management domain. Switch Clustering supports a broad range of standards-based connectivity options and configurations to deliver levels of performance that are scalable to meet customer requirements. Switch Clustering connectivity options for the Catalyst 2900 Series XL include Ethernet, Fast Ethernet, Fast EtherChannel ports, low-cost Cisco GigaStack GBIC, Gigabit Ethernet, and Gigabit EtherChannel ports. Because the technology is not limited by proprietary stacking modules and stacking cables, Cisco Switch Clustering expands the traditional stacking domain beyond a single wiring closet and lets users mix and match interconnections to meet specific management, performance, and cost requirements.

A command switch, either a Catalyst 2900 XL or 3500 XL, provides the proxy and redirection services for single IP address management for each cluster. All cluster management commands are targeted to the command switch IP address. For redundancy, a second switch can be assigned an IP address, and the overall cluster can then be managed using a single virtual IP address. If the primary command switch fails, the backup or secondary command switch seamlessly takes over the management of the cluster while a user still accesses the cluster via the virtual IP address.

Cisco Switch Clustering can be accessed via Cisco Cluster Management Suite (CMS), a Web-based management interface, which allows network administrators to configure, monitor, and manage a switch from anywhere on the network through a standard browser such as Microsoft Internet Explorer or Netscape Navigator. Network administrators simply point their Web-browsers to the IP address of the cluster Command switch and access all management capabilities. The CMS interface is launched from the switch itself and delivers simple, cluster-wide, device-level management, including port configuration, VLAN setup, network views, and port monitoring—all from a single graphical interface. Web-based management is an integral part of the Cisco Switch Clustering architecture, allowing users to easily configure and manage stacks and switch clusters, and administer software upgrades across multiple switches. Command switch and cluster management redundancy are ensured via an automatic failover scheme in the rare event of a command switch failure.

  • 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.
  • Autoconfiguration 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 multifunction LED for port status, half-duplex/full-duplex, and 10Base-T/100Base-T 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.
  • Domain Name Services (DNS) client support provides IP address resolution with user-defined device names.

  • TACACS+ authentication enables centralized control of the switch and restricts unauthorized users from altering the configuration.
  • 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.
  • 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.
