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 10BaseT/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 10BaseT/100BaseT, 100BaseFX, 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 100BaseFX connections in small and midsized campus environments.
The Catalyst 2912MF XL switch, a member of the Catalyst 2900 Series XL family, contains 12 100BaseFX ports and two versatile module slots to provide unmatched expansion capabilities and high-speed connectivity. The modular design allows users to easily add 10BaseT/100BaseT, 100BaseFX, 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.
The Catalyst 2924M-XL and Catalyst 2912MF-XL both feature Cisco Switch Clustering technology. This break- through technology enables up to 16 interconnected Catalyst 2900 XL, 3500 XL, and 1900 switches, regardless of physical proximity, to form a single-IP managed network. Catalyst 2900 XL switches can be clustered using a broad range of connectivity options to meet customer requirements, including Fast Ethernet, Fast EtherChannel® technology, Gigabit Ethernet, Gigabit EtherChannel technology and the Cisco low-cost GigaStack GBIC. Because customers are not limited by proprietary stacking modules and stacking cables, Cisco Switch Clustering technology expands the traditional stacking domain beyond a single wiring closet and lets users "mix and match" interconnections to meet specific manage- ment, performance, and cost requirements.
Catalyst 2900 XL switches can be configured either as command (with command software upgrade) or member switches in a Cisco switch stack or cluster. The command switch serves as the single IP address management point and disburses all management instructions dictated by the network administrator.
The Catalyst 2924M XL and 2912MF-XL switches are an integral component of the complete line of Cisco end-to-end LAN solutions. Integrated Cisco IOS software provides superior functionality for network management, bandwidth aggregation, networked multimedia, and virtual LAN (VLAN) support. Available in Standard and Enterprise editions, the Catalyst 2924M XL switch is upgradable via software, so your investment is protected if your network grows or changes. Catalyst 2912MF-XL switches are available only in Enterprise editions.

The Catalyst 2924M XL features the Cisco Web-based management tool, Cisco Visual Switch Manager (CVSM), which allows network administrators to view and manage the switch from anywhere on the network through a standard browser such as Microsoft Internet Explorer or Netscape Navigator. Launched from the switch itself, CVSM delivers simple network- and device-level management, including port configuration, VLAN setup, network views, and port monitoring. CVSM is an integral part of the Cisco scalable stacking architecture, allowing users to easily configure and manage stacks and switch clusters and to administer software upgrades across multiple switches.
The Cisco Catalyst 2924M XL Standard Edition switch includes several exceptional features to increase network performance for users. Fast EtherChannel or Gigabit EtherChannel technology offers up to 800 Mbps or 4 Gbps of high-performance bandwidth between other Catalyst 2900 XL switches, servers, and other key network stations. Cisco Group Management Protocol (CGMP) enhances performance of multimedia applications and reduces network traffic by allowing a switch to selectively and dynamically forward IP multicast traffic to targeted end stations. Up to 64 port-based VLANs per switch allow data packets to be forwarded only to stations within a specific VLAN, creating a virtual firewall between groups of ports on the network. CVSM, a Web-browser interface, makes all Catalyst 2900 XL switches exceptionally easy to use and manage. CVSM allows network administrators to view and manage the switch from anywhere on the network through a standard browser such as Microsoft Explorer or Netscape Navigator. Multilevel security on the switch console prevents unauthorized users from gaining access and altering the switch configuration. And auto-configuration eases deployment by automatically configuring multiple switches across a network from a single boot server. All Standard Edition switches can be upgraded with the purchase of an optional Enterprise Edition Software Upgrade Kit.
Enterprise Edition software includes all the features of the Standard Edition, and adds enhanced end-to-end VLAN trunk support to your Catalyst 2924M XL/2912MF-XL switch. VLAN trunks can be created from any port using either standards-based 802.1Q protocols or the Cisco Inter-Switch Link (ISL) VLAN architecture. Each Catalyst 2924M XL switch supports up to 64 VLANs to provide broadcast control, enhance network security, and simplify moves, adds, and changes. An Enterprise Edition switch is the best choice for use in a network with enterprise-wide VLAN trunks spanning multiple Cisco routers, chassis switches, and access servers.
