Catalyst 3500 Series XL — Stackable 10/100 and Gigabit Ethernet
Switches
Switches
Product Overview
The Cisco Systems Catalyst 3500 series XL is a scalable line of stackable 10/100 and Gigabit Ethernet switches that deliver
premium performance, manageability, and flexibility, with unparalleled investment protection. This line of low-cost, high-
performance switching solutions provides next-generation stackable switching. Catalyst 3500 XL stacks allow management
of all switched ports from a single IP address and provide interconnected switches with an independent high-speed stack bus
that preserves valuable desktop ports.

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.

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.

Key Features and Benefits
Exceptional Performance
•
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
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
