Cisco Catalyst 3750-X Spotlight
Software Features
Cisco Catalyst 3750-X Series is orderable with three feature sets:
• The LAN Base feature set offers enhanced intelligent services that include comprehensive Layer
2 features.
• The IP Base feature set provides baseline enterprise services, including the support for routed access,
StackPower, and MACsec.
• The IP Services feature set provides full enterprise services that include advanced Layer 3 features
such as 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.
Cisco StackPower Technology
The Cisco Catalyst 3750-X Series introduces
Cisco StackPower technology, an 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. StackPower can
be deployed in either power sharing mode or
redundancy mode. In power sharing mode, the
power of all the power supplies in the stack is
aggregated and distributed among the switches in
the stack. In redundant mode, when the total power
budget of the stack is calculated, the wattage of the
largest power supply is not included. That power
is held in reserve and used to maintain power to
switches and attached devices when one power
supply fails, enabling the network to operate without
interruption. StackPower eliminates the need for an
external redundant power system or installation of
dual power supplies in all the stack members.
MACsec
The Cisco Catalyst 3750-X and 3560-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. In Cisco Catalyst 3750-X and
3560-X Series Switches only the user/down-link
ports (links between the switch and endpoint
devices such as a PC or IP phone) can be secured
using MACsec.
