SERVICE PROVIDER - ETHERNET ACCESS SWITCHES
I. Catalyst 3750 Metro Series
Product Overview
With service provider-friendly hardware and mission-specific software, the Cisco Catalyst 3750 Metro Series
is the first access switch optimized for both the Ethernet-to-the-home (ETTH) triple-play services and
Ethernet-to-the-business (ETTB) VPN services. It provides the most complete security solution for Metro
Ethernet access that covers subscriber, switch, and network protection. The Cisco Catalyst 3750 Metro
Series supports multiple software images to provide a "pay-as-you-grow" deployment model. With service
breadth spanning triple-play and Layer 2 and Layer 3 VPN services, reduced total cost of ownership (TCO)
and operating expenses (OpEx) can be achieved from a single ETTH and ETTB access solution.
The switches feature bidirectional hierarchical quality of service (QoS) and traffic shaping, intelligent 802.1Q
tunneling, VLAN translation, Multiprotocol Label Switching (MPLS), Ethernet over MPLS (EoMPLS), and
Hierarchical Virtual Private LAN Service (H-VPLS) support and redundant AC or DC power. They are ideal
for service providers seeking to deliver profitable business services, such as Layer 2, Layer 3, and MPLS
VPNs, in several bandwidths and with different service-level agreements (SLAs). With flexible software
options, the Cisco Catalyst 3750 Metro Series offers providers a cost-effective path for meeting current and
future service requirements from enterprises and commercial businesses.
