Key Features/Benefits

Exceptional Performance

•Twelve or 24 wire-speed 10BaseT/100BaseTX autosensing ports, each delivering up to 200 Mbps of bandwidth to individual users, servers, or workgroups to support bandwidth-intensive applications

•Two built-in, wire-speed GBIC-based Gigabit Ethernet ports, delivering up to 4-Gbps aggregated bandwidth to Gigabit Ethernet backbones, or Gigabit Ethernet servers, or between switches

•10-Gbps switching fabric and up to 6.5 million packets-per-second forwarding rate, ensuring full-wire speed operation for each 10BaseT/100BaseTX and Gigabit Ethernet port

•4-MB shared memory architecture, ensures the highest-possible throughput with a design that eliminates head-of-line blocking, minimizes packet loss, and delivers better overall performance in environments with extensive multicast and broadcast traffic

•Full-duplex operation on all ports, delivering up to 200 Mbps on 10/100 ports or 2 Gbps on 1000BaseX ports

•8-MB DRAM and 4-MB Flash memory onboard, enabling the addition of a continuous stream of feature upgrades, maximizing customers’ investments

•Dual priority forwarding queues on each 10/100 port and eight priority forwarding queues on all Gigabit Ethernet ports, enabling network traffic prioritization and seamless data, voice, and video integration (enabled in future software)

•Bandwidth aggregation through Fast EtherChannel and Gigabit EtherChannel technology, enhancing fault tolerance and offering from 400 Mbps up to 4 Gbps of aggregated bandwidth between switches, and to routers and individual servers

•Configurable network port, supporting unlimited MAC addresses for backbone connectivity

Flexible and Scalable Switch Clustering and Stacking

•GigaStack GBIC delivers a low-cost, independent stack bus with a 1-Gbps forwarding bandwidth in a daisy-chain configuration, with up to nine Catalyst 3500 XL

or gigabit-enabled Catalyst 2900 series XL switches or a

2-Gbps forwarding rate in a point-to-point configuration

•Cisco switch clustering technology allows a user to manage up to 16 inter-connected Catalyst 3500 XL, 2900 XL, and Catalyst 1900 switches through a single IP address regardless of location

•GBIC-based Gigabit Ethernet ports give customers a choice of 1000BaseSX, 1000BaseLX/LH, or Cisco GigaStack stacking GBICs to fit their connection needs

Ease of Use and Ease of Deployment

•Cluster software upgrade feature allows the network manager to quickly and easily upgrade the system software on a group of Catalyst 3500 XL, 2900 XL, and Catalyst 1900 switches

•IEEE 802.3z-compliant 1000BaseSX and 1000BaseLX/LH physical interface support through a field-replaceable GBIC module provides customers unprecedented flexibility in switch deployment

•Autosensing on each port detects attached device speed and automatically configures the port for 10- or 100-Mbps operation, easing the deployment of the switch in mixed 10BaseT and 100BaseTX environments

•Autonegotiating on all ports automatically selects half- or full-duplex transmission mode to optimize bandwidth

•Autoconfiguration eases deployment of switches in the network by automatically configuring multiple switches across a network via a boot server

•Default configuration stored in Flash memory ensures that a switch can be quickly connected to the network and can pass traffic with minimal user intervention, preserving configuration in case of a power outage

3524 XL, 3512 XL specifications

Cisco Systems has long been a leader in networking technology, and the Catalyst 3524 XL and 3512 XL switches exemplify the company’s commitment to providing high-performance, scalable solutions for businesses. These devices, part of the Catalyst 2900 series, are known for their robust features, catering to the needs of both enterprise and small office environments.

The Cisco Catalyst 3524 XL switch offers twenty-four 10/100 Mbps Ethernet ports, allowing for fast data transmission and efficient handling of network traffic. One of the standout features of the 3524 XL is its ability to support Power over Ethernet (PoE), which simplifies the deployment of devices such as IP phones and wireless access points by delivering power through the Ethernet cable. With a switching capacity of up to 8.8 Gbps, it ensures minimal congestion and high performance, making it an ideal choice for organizations looking to enhance their network infrastructure.

In contrast, the Cisco Catalyst 3512 XL switch is a more compact option, offering twelve 10/100 Mbps Ethernet ports. This model is particularly suited for small networks that do not require the extensive port density of larger switches. The 3512 XL benefits from similar technologies as its larger counterpart, including support for fast Ethernet and the ability to handle multiple network protocols effectively, ensuring seamless integration into existing systems.

Both the 3524 XL and 3512 XL switches support a range of advanced networking features, such as VLAN (Virtual Local Area Network) support, which enables network segmentation for improved security and performance. Additionally, they incorporate Cisco's own Quality of Service (QoS) technology, which prioritizes traffic flow and ensures that critical applications receive the necessary bandwidth.

Another key characteristic shared by both models is their reliability and ease of management. The switches are designed to be user-friendly, featuring an intuitive interface and support for SNMP (Simple Network Management Protocol), which allows network administrators to monitor performance and manage devices efficiently.

Overall, Cisco's Catalyst 3524 XL and 3512 XL switches provide organizations with essential features and technologies that support a robust, scalable networking environment. Their combination of performance, power management capability, and advanced networking features makes them valuable assets for businesses looking to build a reliable and efficient network infrastructure.
