Long-Reach Ethernet Switches
Cisco's Long Reach Ethernet switches meet the demands of high bandwidth
applications while leveraging existing copper wiring infrastructures. Catalyst

2950
Long-Reach Ethernet (LRE) Series switches enable enterprise and service provider
customers to extend intelligent Ethernet services over existing phone and legacy
wiring, at distances of up to 5000 feet. Cisco is the only company with the breadth of
technologies that allow customers to deliver intelligent network services across any
combination of wired and wireless infrastructures.
The Cisco Catalyst 2950 LRE solution delivers cost-effective, high-performance broadband
access to enterprise campus environments and multi-tenant buildings (such as, hotels,
apartment buildings, and office buildings). The Cisco LRE technology dramatically extends
the reach of Ethernet up to 5,000 feet over existing Category 1/2/3 wiring at speeds from 2
to 15 Mbps symmetric. LRE co-exists on the same medium as Plain Old Telephone Service
(POTS), digital telephone, and ISDN traffic, and co-exists with asymmetric digital subscriber
line (ADSL) in the same wire bundle, allowing service providers to provision LRE to buildings
where broadband services already exist.
Enterprise
The Catalyst 2950 LRE enables enterprises to deploy productivity enhancing applications across
their entire network while avoiding the costs of rewiring. Based on Cisco's market leading
Catalyst 2950 Series, the 2950 LRE is a familiar product for existing Cisco customers and allows
networks to reach areas previously not feasible due to wiring or distance limitations.
Metro Access
Ideal for metro Ethernet access in residential and small-office, home-office (SOHO) markets,
the Catalyst 2950 LRE switches extend intelligence to the metro access edge, enabling service
breadth, availability, security, and manageability while leveraging the existing in-building
wiring. Featuring advanced rate limiting, voice virtual LAN (VLAN) support, and multicast
management, these switches enable a variety of residential metro services such as Internet
access, voice over IP (VoIP), and broadcast video.
Hospitality
The Catalyst 2950 LRE broadband networking solution enables hoteliers to deliver secure
high-speed Internet access to guest and conference rooms to attract and retain business
travelers. By deploying the Cisco LRE solution, hotel owners can future proof their buildings
for a wide range of applications that will ensure operational efficiency and customer loyalty
for years to come while avoiding the costs of rewiring.

- Page 5 LRE, 3500 XL, 2900 XL, and 2900 LRE XL switches. Through Cisco Switch Clustering technology, users access Cisco CMS with any standard Web browser to manage up to 16 of these switches at once, regardless of their geographic proximity—with the option of using a single IP address for the entire cluster if desired. With the addition of the Catalyst 3550 switches, Cisco CMS Software can now extend beyond routed boundaries for even more flexibility in managing a Cisco cluster.
- Page 6 EtherChannel, Gigabit Ethernet, and Gigabit EtherChannel connectivity. Because Cisco Switch Clustering technology is not limited to a single stack of switches, Cisco CMS Software expands the traditional cluster domain beyond a single wiring closet and saves time and effort for network administrators.
