For mid-sized organizations and enterprise branch offices, the Cisco Catalyst 3750 Series eases deployment of
converged applications and adapts to changing business needs by providing configuration flexibility, support for
converged network patterns, and automation of intelligent network-services configurations. In addition, the
Cisco Catalyst 3750 Series is optimized for high-density Gigabit Ethernet deployments and includes a diverse
range of switches that meet access, aggregation, or small-network backbone-connectivity requirements.
Configurations
• Cisco Catalyst 3750G-24TS—24 Ethernet 10/100/1000 ports and 4 SFP uplinks
• Cisco Catalyst 3750G-24T—24 Ethernet 10/100/1000 ports
• Cisco Catalyst 3750G-12S—12 Gigabit Ethernet SFP ports
• Cisco Catalyst 3750-48TS—48 Ethernet 10/100 ports and 4 SFP uplinks
• Cisco Catalyst 3750-24TS—24 Ethernet 10/100 ports and 2 small form-factor pluggable (SFP) uplinks
• Cisco Catalyst 3750-48PS—48 Ethernet 10/100 ports and 4 SFP uplinks with IEEE 802.3af and Cisco
pre-standard Power over Ethernet (PoE)
• Cisco Catalyst 3750-24PS—24 Ethernet 10/100 ports and 2 SFP uplinks with IEEE 802.3af and Cisco
pre-standard Power over Ethernet (PoE)

Cisco Catalyst 3750 Series is available in the Standard Multilayer Software Image (SMI) or the Enhanced Multilayer
Software Image (EMI). The SMI feature set includes advanced quality of service (QoS), rate-limiting, access control
lists (ACLs), and basic static and routed information protocol (RIP) routing functionality. The EMI provides a richer
set of enterprise-class features including advanced hardware-based IP unicast and multicast routing.
Cisco StackWise Technology—A New Standard in Stackable Resiliency
Cisco StackWise technology is a premium stacking architecture optimized for Gigabit Ethernet. This technology
is designed to respond to additions, deletions, and redeployment while maintaining constant performance.
Cisco StackWise technology unites up to nine individual Cisco Catalyst 3750 switches into a single logical unit, using
special stack interconnect cables and stacking software. The stack behaves as a single switching unit that is managed
by a master switch elected from one of the member switches. The master switch automatically creates and updates
all the switching and optional routing tables. A working stack can accept new members or delete old ones without
service interruption.
Key Features and Benefits
Ease of Use—"Plug-and-Play" Configuration
A working stack is self-managing and self-configuring. When switches are added or removed, the master switch
automatically updates all the routing tables to reflect changes. Upgrades are applied universally and simultaneously
to all members of the stack.
