Data Sheet

Cisco Catalyst 3750-E Software

Cisco Catalyst 3750-E Series is available with either the IP Base or the IP Services feature set. The IP Base feature

set includes advanced quality of service (QoS), a suite of security features, rate-limiting, access control lists, basic

static, Routing Information Protocol (RIP), and OSPF routing capability. The IP Services feature set provides a richer

set of enterprise-class features, including advanced hardware-based IP unicast and multicast routing—Enhanced

Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), Border Gateway Protocol (BGP),

Protocol Independent Multicast (PIM), and IPv6 routing such as OSPFv3 and EIGRPv6.

Customers can transparently upgrade the software feature set in the Cisco Catalyst 3750-E Series Switches through

Cisco IOS

Software Activation. Software activation authorizes and enables the Cisco IOS Software feature sets. A

special file contained in the switch, called a license file, is examined by Cisco IOS Software when the switch is

powered on. Based on the license’s type, Cisco IOS Software activates the appropriate feature set. License types

can be changed, or upgraded, to activate a different feature set. For detailed information about Software Activation,

Investment Protection

The Cisco Catalyst 3750-E Series Switches are compatible with the Cisco Catalyst 3750 Series Switches, enabling

customers to stack them together and thereby protect existing investment in the Cisco Catalyst 3750 Series

Switches. The Cisco TwinGig Small Form-Factor Pluggable (SFP) converter module further protects customers’

investment in Cisco Catalyst 3750-E Series Switches by enabling migration from Gigabit Ethernet to 10 Gigabit

Ethernet uplinks, as business needs require, without having to upgrade the switches.

Cisco StackWise Plus Technology

Cisco StackWise Plus technology is built on the highly successful StackWise

™

technology, which is a premium

stacking architecture optimized for Gigabit Ethernet. StackWise technology was designed to respond to additions,

deletions, and redeployment while maintaining constant performance. 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. StackWise creates a highly resilient single unified system of up to nine

switches, providing simplified management using a single IP address, single telnet session, single command-line

interface (CLI), auto-version checking, autoconfiguration, and more. StackWise Plus supports all the features of

StackWise and provides backward compatibility with the existing Cisco Catalyst 3750 Series Switches while

enhancing the throughput of the system up to 64 Gbps. StackWise Plus also enables local switching in Cisco

Catalyst 3750-E Series Switches. Local switching packets coming into a port in the Cisco Catalyst 3750-E Series

Switch destined for another port in the same switch do not have to traverse through the stack ring, thus increasing

the forwarding capacity of the switch.

Cisco EnergyWise Technology

Cisco EnergyWise is an innovative architecture, added to the Cisco Catalyst 3750-E switches, promoting

companywide sustainability by reducing energy consumption across an entire corporate infrastructure and affecting

more than 50 percent of global greenhouse gas emissions created by worldwide building infrastructure, a much

greater effect than the 2 percent generated by the IT industry. Cisco EnergyWise enables companies to measure the

power consumption of network infrastructure and network-attached devices and manage power consumption with

specific policies, reducing power consumption to realize increased cost savings, potentially affecting any powered

device.
