7. Catalyst 3500 Series XL — Stackable 10/100 and Gigabit Ethernet 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, highperformance 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. 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

basis, providing a common management interface for Cisco routers, switches, and hubs • Embedded Remote Monitoring (RMON) software
agent supports four RMON groups (history, statistics, alarms, and events) for enhanced traffic management, monitoring, and analysis • IEEE
802.1p Layer-2 prioritization protocol ready, allowing users to assign data packets to prioritized forwarding queues Cisco 1000BaseT GBIC—
Gigabit Interface Converter The Cisco 1000BaseT Gigabit Interface Converter (GBIC) is an ideal solution for Catalyst 3500 Series XL and Catalyst
2900 Series XL customers, providing full duplex Gigabit Ethernet connectivity to high-end workstations and between wiring closets over
existing

8. copper infrastructures. The GBIC technology leverages the industry’s flexible, standards-based 1000BaseX design allowing for a simple and
low-cost migration path to Gigabit Ethernet. The availability of the new 1000BaseT GBIC increases the deployment and application flexibility
of the Catalyst 3500 Series XL and 2900 Series XL with a range of media transceivers that include multiple stacking options, short-and long-
haul fiber, and copper connectivity (including SX, LX/LH, ZX, TX, and Cisco GigaStack converters). For more information, see Specifications

switches are used mostly for desktop connectivity with limited aggregation. Gigabit Ethernet ports will be used for uplinks to corporate
backbone or connections to a Gigabit aggregation switch. Illustrated here are three sample configurations: Independent Stack Bus, Point-to-
Point Connections, and Cisco Switch Clustering. Performance levels scale from a 1 Gbps forwarding rate in a daisy-chain configuration up to a
2 Gbps forwarding rate in a point-to-point connection. 4 Cisco Product Catalog, April, 2002 _x000C_Figure 21-7: Creating an Independent
