Features

Cisco StackWise Plus technology
Cisco StackWise Plus technology is built on the highly successful industry leading StackWise technology,which is a premium stacking architecture optimized for GbE. StackWise technology was designed to respond to additions,deletions,and redeployment while maintaining constant performance. 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,auto configuration,and more. StackWise Plus supports all the features of StackWise and provides backward compatibility with the existing Cisco Catalyst 3750-X series switches while enhancing the throughput of the system up to 64 Gbps. StackWise Plus also enables local switching in Cisco Catalyst 3750-X series switches.

Cisco StackPower technology
The Cisco Catalyst 3750-X series introduces Cisco StackPower technology,innovative power interconnect system that allows the power supplies in a stack to be shared as a common resource among all the switches. Cisco StackPower unifies the individual power supplies installed in the switches and creates a pool of power,directing that power where it is needed. Up to four switches can be configured in a StackPower stack with the special connector at the back of the switch using the StackPower cable.

MACsec
The Cisco Catalyst 3750-X series switches offer exceptional security with integrated hardware support for MACsec defined in IEEE 802.1AE. MACsec provides MAC layer encryption over wired networks using out-of-band methods for encryption keying. The MACsec Key Agreement (MKA) protocol provides the required session keys and manages the keys required for encryption when configured. MKA and MACsec are implemented following successful authentication using 802.1x Extensible Authentication Protocol (EAP) framework.

Dual redundant modular power supplies
The Cisco Catalyst 3750-X series switches support dual redundant power supplies. The switch ships with one power supply by default and the second power supply can be purchased at the time of ordering the switch or at a later time. If only one power supply is installed,it should always be in the power supply bay.

Borderless security
The Cisco Catalyst 3750-X series switches provide superior layer 2 threat defense capabilities for mitigating man-in-the-middle attacks (such as MAC,IP,and ARP spoofing). TrustSec,a primary element of borderless security architecture,helps enterprise customers secure their networks,data and resources with policy-based access control,identity and role-aware networking,pervasive integrity,and confidentiality.
