Cisco WS-C3750G-12S-E Catalyst Ethernet Switch

The Cisco WS-C3750G-12S-E Catalyst is a 1U, stackable multilayer switch in the Catalyst 3750G family that provides 12 SFP-based Gigabit Ethernet ports for fiber-based access and distribution. It delivers 32-Gbps of stacking bandwidth via StackWise and supports a stack of up to nine switches, enabling scalable, single-management network growth. Running the IP Services software image, it offers enterprise-class intelligent services at the network edge, including IPv6 dynamic routing. With 128 MB of DRAM and 32 MB of Flash, the device supports up to 12,000 MAC addresses and up to 20,000 unicast routes, and it achieves a forwarding rate of about 17.8 Mpps for typical Gigabit traffic. The switch supports jumbo frames up to 9000 bytes (MTU) to improve performance for storage, virtualization, and data-transfer-heavy workloads. This model is designed for environments needing reliable Layer 2/3 switching with IPv6 support in a compact, rack-mountable form factor.
