Table 1 Features and Beneﬁts Summary—Catalyst 3500 Series XL

Feature Description Beneﬁt

10BaseT/100BaseTX Support 12, 24, or 48 autosensing 10BaseT/100BaseTX ports (Catalyst

3512XL, 3524 XL, and 3548 XL)

Delivers up to 200 Mbps of bandwidth per port for individual

users, server farms, or workgroups to support bandwidth-intensive

applications

Gigabit Ethernet Support Two built-in, GBIC-based Gigabit Ethernet ports (Catalyst 3512

XL, 3524 XL, and 3548 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

Class of Service Prioritization IEEE 802.1p combined with two priority queues on 10/100 Provides quality-of-service and ability to prioritize mission

critical and time sensitive trafﬁc from data, voice, and telephony

applications

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 associated with appropriate network resources, trafﬁc

patterns, and bandwidth

Support for standards-based IEEE 802.1Q and Cisco ISL VLAN

trunking protocols

Enables deployment of up to 250 enterprise-wide, end-to-end

VLANs 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 10.8-Gbps switching fabric and up to a 8.0-Mpps forwarding rate Delivers premium performance to each 10BaseT/100BaseTX port

4 MB shared-memory architecture Ensures the highest-possible throughput by eliminating

head-of-line blocking; minimizes packet loss and reduces

congestion from multicast and broadcast trafﬁc

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

Cisco Group Management Protocol (CGMP) Enables a switch to selectively and dynamically forward routed IP

multicast trafﬁc to targeted multimedia end stations, reducing

overall network trafﬁc

Bandwidth aggregation through Fast EtherChannel technology or

Gigabit EtherChannel

Delivers up to 8-Gbps of bandwidth between switches, routers,

and individual servers

Enhances fault tolerance

Per-port broadcast storm control Prevents faulty end stations from degrading overall systems

performance with broadcast storms

Flexible Stacking and Scalable

Switch Clustering Technology

Hardware-based independent stacking bus delivered through

GigaStack GBIC supports multiple stacking options

Delivers up to 1-Gbps forwarding bandwidth to a cascade of up 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 of management with a

broad range of connectivity options to up to 16 interconnected

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

single IP address
