Cisco Catalyst 3750 Series Switches
Key Features
• Stackable, fixed-configuration switches with Cisco
StackWise™ technology and a 32-Gbps interconnect
for a unified, resilient system of up to nine switches
• Layer 2-4 switching and intelligent services with dynamic
IP routing and IPv6
• Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet
connectivity
• Up to 48 10/100/1000 ports plus 4 Small Form-Factor Pluggable (SFP) ports per stackable switch
• Integrated Power over Ethernet (PoE) (Cisco pre-standard and IEEE 802.3af); up to 24 ports with 15.4 watts (W) or 48 ports with 7.3W
• Integrated wireless LAN controller supporting up to 200 access points
• AC power supply failure protection with external redundant power supply

Key Benefits
Availability—802.1S/W enables standards-based fault tolerance, load balancing, and rapid recovery; Flexlink provides sub 100-millisecond convergence; Per VLAN Spanning Tree Plus (PVST+) increases available bandwidth by allowing traffic on redundant link

Cisco StackWise™ Technology—One IP address and one command-line interface (CLI) simplify management; a 32-Gbps resilient -architecture speeds convergence; 1:N stack master redundancy and Layer 3 uplink resilience as well as cross-stack Cisco EtherChannel® technology and QoS increase availability; autoconfiguration and Cisco IOS® Software version check and update accelerate deployment; hot add and delete of switches
keep the stack running

Power over Ethernet (PoE)—370W PoE simplify IP telephony, wireless, and video surveillance deployments; intelligent powermanagement features provide greater control and help extend the power budget; combined with Fast Ethernet or Gigabit Ethernet maximizes existing infrastructure investment

Layer 3—Advanced routing protocols like Open Shortest Path First (OSPF), Enhanced Interior Gateway Routing Protocol (EIGRP), Border Gateway Protocol (BGP), Static Routing, and Policy Based Routing (PBR) increase network scale; equal-cost routing as well as multicast routing such as Protocol Independent Multicast (PIM) maximize network resources; Virtual Route Forwarding Lite (VRF-Lite) secures traffic; IPv6 simplifies network addressing and mobile IP while increasing security

QoS—Traffic Shaping smoothes bursty traffic flows without dropping packets; shaped Round Robin helps guarantee bandwidth to mission-critical applications; Scavenger Queueing protects
against worms that can overload resources Management—Cisco Smartports allows fast and easy configuration of advanced Cisco Catalyst intelligent features; express setup facilitates quick and easy setup through a Web-based interface; resource templates help tailor switch resources for the application

Security—Dynamic Host Configuration Protocol (DHCP) snooping allows only trusted ports to relay DHCP messages, eliminating rogue DHCP servers; Network Access Control (NAC) prevents the propagation of costly worms and viruses; Dynamic ARP Inspection and IP Source Guard prevent against man-in-themiddle attacks; 802.1x and Identity-Based Network Services allow only authorized persons on the network; port security prevents MAC address flooding attacks Wireless—Integrated

wireless LAN controller delivers centralized security policies, intrusion protection, RF management, QoS and Layer 3 fast secure roaming for Wireless LANs (WLANs)

Customers
The Cisco Catalyst 3750 Series solutions are ideal for:• Customers with 250 or more employees who need network equipment to enhance business productivity
• Customers who expect resiliency, security, and scalability
• Customers who want to quickly deploy and easily manage their networks
• Customers who are planning to deploy IP telephony, wireless, or gigabit-to-the-desktop (GTTD)
