Table 1 Features and Beneﬁts Summary: Catalyst 3500 Series XL

Feature Description Beneﬁt

10BaseT/100BaseTX support 12 or 24 autosensing 10BaseT/100BaseTX ports

(Catalyst 3512 XL and 3524 XL)

Delivers wire-speed performance withup to 200 Mbps ofbandwidth

per port for individual users, server farms, orworkgroups to support

bandwidth-intensive applications

Gigabit Ethernet Support Two built-in, GBIC-based GigabitEthernet ports (Catalyst3512

XL and 3524 XL)

Delivers up to 4-Gbps aggregated bandwidth to Gigabit Ethernet

backbone, to Gigabit Ethernet-connected server farms or between

switches

GBIC-Based Gigabit Ethernet

Aggregation

Eight ﬁxed Gigabit Ethernet ports (Catalyst 3508G XL) Delivers up to 5-Gbps aggregated forwarding bandwidth to

connected switches in a point-to-point conﬁguration

Virtual LANs on All Ports Up to 250 port-based VLANs per Catalyst 3500 series XL

support

Improve performance and scalability by assigning users to VLANs

associatedwith appropriatenetworkresources, trafﬁcpatterns,and

bandwidth

Support for standards-based IEEE 802.1Qand Cisco ISL VLAN

trunking protocols (Enterprise Editions only)

Enables deploymentof upto 250enterprise-wide, end-to-endVLANs

per 3500 series XL switch, spanning multiple routers, switches, and

access routers

Reduces administrative costs and simpliﬁes network moves, adds,

and changes

Enables better management and control of broadcast and multicast

trafﬁc

Improves network security by establishing separate VLAN groups

for high-security users and relocating workgroup servers into

secured centralized areas

Outstanding Performance 10-Gbps switching fabric and up to 7.5 million

packets-per-second forwarding rate

Delivers wire-speed performance to each 10BaseT/100BaseTX port

4-MB shared-memory architecture Ensures the highest-possible throughput byeliminating head-of-line

blocking; minimizes packet loss and reduces congestion from

multicast and broadcast trafﬁc

8-MB DRAM and 4-MB Flash memory onboard Enables delivery of a continuous stream of software upgrades and

enhancements, maximizing customers’ return on investment

Full-duplex operation on switched 10/100 ports Delivers up to 200 Mbps of bandwidth to end stations and servers,

and between switches

CGMP Fast Leave Allows quick stoppage of multicasts to end stations that want to

drop a data stream, reducing superﬂuous trafﬁc on the network

Flexible and Scalable Switch

Clustering Technology

to nine Catalyst 3500 series XL and gigabit-enabled Catalyst 2900

series switches or 2-Gbps forwarding bandwidth in a point-to-point

conﬁguration

High-performance aggregation using the Catalyst 3508G XL Delivers up to 5-Gbps aggregated forwarding rate to a stack of

switches in a point-to-point conﬁguration

Cisco Switch Clustering technology Delivers ﬂexibility,scalability,and ease ofmanagement witha broad

range of connectivity options to up to 16 interconnected Catalyst

3500 XL, 2900 XL, and Catalyst 1900 switches managed from a single

IP address

Ease of Use and Ease of Deployment Cluster software upgrade Allows a network administrator to quickly and easily upgrade

system software for up to 16 interconnected Catalyst 3500 XL,

2900 XL, and Catalyst 1900 switches through a single CLI

command or an easy-to-use CVSM interface

IEEE 802.3z-compliant 1000BaseSX and 1000BaseLX/LH

physicalinterface supportthrougha ﬁeld-replaceableGigaBit

Interface Converter (GBIC)

Provides standards-based technology and unprecedented ﬂexibility

in switch deployment

Cisco Visual Switch Manager interface Easy-to-use, Web-based interface allows switch management from

anywhere in the Intranet with a Web browser

Autosensing on each 10/100 port Detects attached device speed and automatically conﬁgures the

port for 10- or 100-Mbps operation, easing switch deployment in

mixed 10BaseT and 100BaseTX environments

Autonegotiating on each 10/100 port Automatically selects half- or full-duplex transmission mode to

optimize bandwidth

Default conﬁguration stored in Flash memory Ensures that a switch can be connected to a network and can pass

trafﬁc with minimal user intervention

19-inch, rack-mountable Catalyst 3508G XL, 3512 XL, and 3524

XL are each available in one rack-unit-high (1.73 in.)

enclosure

Compliant with standard 19-inch, rack-mount scheme for easy

installation; allows high-density port allocation while conserving

valuable rack space in the wiring closet
