Applications

The three major product applications of the Catalyst 3500 series

XL are deﬁned as follows:

• Enterprise Wiring Closet—Catalyst 3500 series XL switches

are deployed in the wiring closet at the enterprise edge,

aggregated by Catalyst 4000/5X00/6X00 switches that

implement multilayer services in the network core.

• Midmarket/Branch Ofﬁce LAN—Catalyst 3500 series XL

switches are deployed as the primary LAN backbone and

desktop connectivity solutions in smaller site installations.

• Low-Cost Multilayer Network—When deployed together with a

Layer 3 switch, the Catalyst 3500 series XL product line offers

a high- performance multilayer solution for cost-conscious

users.

Enterprise Wiring Closet

The Catalyst 3500 series XL creates a very cost-effective and

scalable solution for enterprise wiring closet connectivity (Figure

3). Users can deploy high-performance 10/100 and Gigabit

Ethernet solutions that will support bandwidth- intensive

applications. Customers have the capability to implement

GigaStack stacking and to link each switch to the network core

over Gigabit Ethernet uplinks. Switched uplinks to a Cisco

Catalyst network core use the 3500 XL’s high-performance and

high-availability features, including: dual redundant uplinks,

Uplink Fast, PVST+, Gigabit EtherChannel technology, and other

features. QoS and Cisco AVVID (Architecture for Voice, Video,

and Integrated Data) are supported from the desktop to the

network core. The Catalyst 3500 XL supports IEEE 802.1p to

prioritize and queue trafﬁc of connected desktops at the network

edge.
