Cisco Catalyst 3750-E Series Spotlight
Simplified Management
Software Features
Cisco Catalyst 3750-E Series is orderable with two feature sets: 
•  The IP Base feature set includes advanced QoS, security, and basic routing functionality.
•   The IP Services feature set provides a richer set of enterprise-class features, including advanced 
hardware-based IP unicast and multicast routing as well as Virtual Route Forwarding (VRF), and  
policy-based routing (PBR).
Upgrades
•  The IP Advanced Services software license can be purchased separately to enable IPv6 routing.

Cisco StackWise Plus Technology
A unique stacking architecture optimized for 
Gigabit and 10 GBE, this technology is designed to 
respond to additions, deletions, and redeployment 
while maintaining constant performance. It unites up 
to nine individual Cisco Catalyst 3750-E switches 
into a single logical unit, using special interconnect 
cables and stacking software. Cisco Catalyst 
3750-E switches can also be stacked with existing 
Catalyst 3750 switches. The stack is managed as a 
single switching unit controlled by a master switch 
elected from one of the member switches. The 
master switch automatically creates and updates 
all the switching and routing tables. A working stack 
can accept new members or delete old members 
without service interruption.
Addition of IP Communications
Cisco Catalyst 3750-E Series PoE models support 
Cisco IP phones and Cisco Aironet
®
 wireless 
LAN (WLAN) access points, as well as any IEEE 
802.3af–compliant end device. The Catalyst 3750-E 
24-port models can support 24 simultaneous 
full-powered PoE ports at 15.4 W for maximum 
powered device support. The 48-port versions can 
deliver the necessary power to support all 48 ports 
at 15.4W. 
Available for the Catalyst 3750-E Series, Cisco Network Assistant is a centralized management application 
that simplifies the administration task of Cisco switches, routers, and wireless access points. Free of 
charge, Cisco Network Assistant provides configuration wizards that greatly simplify the implementation of 
converged networks and intelligent network services.
