Catalyst 3000 Series

The Catalyst 3000 series switches provide end user access ports for the wiring closet. The
switches are available in several models such as the Catalyst 3560, 3560-E, 3750, 3750-E,
and 3100. The Catalyst 3000 series is a midline switch that can offer Layer 2 services or
both Layer 2 and Layer 3 services in the same device, depending on the software. The
switch comes in different port densities and offers Fast Ethernet, Gigabit Ethernet, and
Ten Gigabit Ethernet support. This switch series has ports that can be directly configured
as Layer 3 interfaces or can use VLAN interfaces for Layer 3 switching. It also supports
Layer 2 functionalities on a port-by-port basis for basic Layer 2 connectivity and
enhanced features such as trunking, channeling, QoS classification and marking, in addi-
tion to access control for Layer 2 or Layer 3 ports. The Cisco Blade Switch 3100 series
are used in the Data Center Access integrated into blade chassis. The Catalyst 3100,
3750, and 3750-E offer hardware stacking, high levels of resiliency, automation, and sin-
gle point of management; with Cisco StackWise technology, customers can create a sin-
gle, 64-Gbps switching unit with up to nine switches.
Here is the performance for the Catalyst 3xxx series switches:
