Description

The Catalyst 3750-X is a stackable Layer 3 switch built for enterprise access and aggregation in fibre-based wiring closets. This model provides 12 Gigabit Ethernet SFP downlink ports in a 1RU chassis, with routed access and stack resiliency for campus and branch deployments.

The 12 downlinks accept standard SFP modules, and there is no PoE on this SKU. It is powered by a 350W AC supply (100-240 VAC) and has a 160 Gbps switching fabric with a forwarding rate of 35.7 mpps. An optional uplink network module slot adds 4x 1G SFP, 2x 10G SFP+ or 2x 10GBASE-T, and typical consumption sits at roughly 86 to 128 W depending on the module fitted. It ships with the IP Base feature set, which includes routed access, StackPower, MACsec and 1K VLANs, and can be upgraded to IP Services through a licence.

StackWise Plus delivers 64 Gbps of stack throughput with other Catalyst 3750-X switches. The supported uplink modules are C3KX-NM-1G, C3KX-NM-10G, C3KX-NM-10GT and the C3KX-SM-10G service module.
