Catalyst 3512 XL and 3524 XL Stackable 10/100 and Gigabit Ethernet Switches

Cisco Catalyst 3500 series XL switches take stacking to a new level with revolutionary Cisco Switch Clustering technology and GigaStack GBICs. With Cisco Switch Clustering, users can manage over 380 ports from a single IP address, and connect up to 16 switches, regardless of physical location, with a broad range of Ethernet, Fast Ethernet, and Gigabit Ethernet media. Cisco Switch Clustering is supported on all Catalyst 3500 XL, 2900 XL and Catalyst 1900 switches.

All Catalyst 3500 series XL switches feature Cisco IOS software and Cisco Visual Switch Manager (CVSM) software, an easy-to-use Web-based management interface. All high-performance Catalyst 3500 series XL switches are available in either Standard or Enterprise Editions. Enterprise Edition switches offer advanced software features, including complete 802.1Q and ISL VLAN support, TACACS+ security, and fault tolerance through Uplink Fast.

With a 10-Gbps switching fabric and a maximum 6.5-million-packet-per second, wire-speed forwarding rate, these switches are ideal for creating high-performance local-area networks.

The Catalyst 3512 XL switch has 12 10/100 switched ports and two Gigabit Interface Converter (GBIC)-based Gigabit Ethernet ports, and the Catalyst 3524 XL has 24 10/100 ports and two GBIC-based Gigabit Ethernet ports. The built-in Gigabit Ethernet ports accommodate a range of GBIC transceivers, including the Cisco GigaStack GBIC, and 1000BaseSX and 1000BaseLX/LH GBICs.
The Catalyst 3500 series XL family includes three switch models and the

Cisco GigaStack Gigabit Interface Converter (GBIC):

Catalyst 3512 XL---A single rack unit (RU) stackable 10/100 and Gigabit Ethernet switch with 12 10BaseT/100BaseTX ports and two GBIC-based Gigabit Ethernet ports. The two Gigabit ports accommodate a range of industry-standard GBICs, including the Cisco GigaStack GBIC, 1000BaseSX, and 1000BaseLX/LH GBICs. The Catalyst 3512 XL is a high-performance, nonblocking switch, ideal for aggregating a small group of Catalyst 2900 series XL or Catalyst 1900 switches in a clustered configuration. In a standalone or stacked configuration, the Catalyst 3512 XL offers low port density at a low entry price.

Catalyst 3524 XL---A single RU stackable 10/100 and Gigabit Ethernet switch with 24 10BaseT/100BaseTX ports and two GBIC-based Gigabit Ethernet ports. The Catalyst 3524 XL is ideal for delivering dedicated 10 or 100 Mbps to individual users and servers in a stack or cluster configuration. Built-in dual GBIC-based Gigabit Ethernet ports provide users with a flexible and scalable solution for Gigabit Ethernet uplinks or GigaStack GBIC stacking.

Catalyst 3508G XL---A single RU stackable Gigabit Ethernet switch with eight GBIC-based Gigbit Ethernet ports. The Catalyst 3508G XL is ideal for aggregating a group of 10/100 and Gigabit Ethernet switches and Gigabit Ethernet servers through Cisco GigaStack GBICs or standard 1000BaseX GBICs.

GigaStack GBIC---A versatile, low-cost, Gigabit Ethernet stacking GBIC that offers high-speed interconnectivity between Catalyst 3500 series XL and gigabit-enabled Catalyst 2900 series XL switches. The GigaStack GBIC is ideal for performance- and cost-conscious customers who require an independent stack bus to interconnect multiple Catalyst 3500 XL and gigabit-enabled Catalyst 2900 XL switches.

The switches' dual GBIC-based Gigabit Ethernet ports provide an ultra-flexible and scalable solution for Gigabit Ethernet uplinks or GigaStack GBIC stacking solutions. Available in Standard and Enterprise Editions, the Catalyst 3512 XL and Catalyst 3524 XL switches are software upgradable, so your investment is protected and your LAN can grow and evolve with your network requirements. The switches are easy to deploy, either on a desktop or in a wiring closet, and feature Cisco IOS^® software support.

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 managed single IP address network.

In a Cisco Switch Cluster, one Catalyst 3500 series XL or 2900 XL switch is specified as the "command" switch and all other switches in the cluster are designated as "member" switches. The command switch serves as the single IP address management point and disburses all management action dictated by the network administrator. Command switches can cluster up to additional 15 interconnected member switches regardless of their interconnection media. Cisco Switch Clustering command software is preinstalled on all Catalyst 3500 series XL switches and is available as an upgrade for Catalyst 2900 series XL switches with the Catalyst 2900 XL Command Software upgrade kit.

Standard Edition Software

Cisco Catalyst 3500 series XL Standard Edition switches include several exceptional features to increase network performance, manageability, and security.

The command switch feature delivers single-IP managed Cisco Switch Clustering technology to up to 16 interconnected Catalyst 3500 XL, 2900 XL, or Catalyst 1900 switches. Fast EtherChannel and Gigabit EtherChannel technology offer from 400-Mbps to 4-Gbps high-performance bandwidth among Catalyst switches, routers, and servers.
The 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 250 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.
Network Time Protocol (NTP) provides a unified clock across the network, ensuring accurate time stamps for troubleshooting all network events. MAC-based port level security prevents unauthorized stations from accessing the switch. Multilayer security on the switch console prevents unauthorized users from accessing or altering switch configuration.

All Standard Edition switches can be upgraded with the purchase of an optional Catalyst 3500 XL Enterprise Edition upgrade kit.

Enterprise Edition Software

Enterprise Edition software includes all of the features of the Standard Edition and adds enhanced end-to-end VLAN support to your Catalyst 3500 series XL switch.

Virtual LAN trunks can be created from any port using either 802.1Q trunking or the Cisco Inter-Switch Link (ISL) VLAN architecture. VLANs using standards-based 802.1Q and ISL trunking provide broadcast control and enhanced security, and simplify adds, moves, and changes.
TACACS+ authentication enables centralized access control of the switch and restricts unauthorized users from altering the configuration. Uplink Fast technology ensures quick failover recovery, enhancing overall network stability and reliability.
An Enterprise Edition switch is the best choice for use in a network with the requirement of higher level of security, superior fail safe redundancy, and end-to-end VLANs spanning multiple routers, switches, and access servers.
