Cisco ME-3400EG-12CS-M Ethernet Access Switch

The Cisco ME-3400EG-12CS-M Ethernet Access Switch is a fiber-based, Layer 2 switching platform designed for service provider and enterprise metro Ethernet networks, delivering secure VLAN segmentation and scalable access and aggregation fiber connectivity. It provides 12× Gigabit Ethernet SFP fiber ports and 2× dual‑purpose Gigabit Ethernet ports (RJ-45/SFP), supporting up to 44 Gbps of switching capacity and up to 32.7 Mpps forwarding, making it suitable for high‑density edge and aggregation links. Part of the Cisco ME 3400E Series, it supports advanced metro Ethernet features and VLANs, ACLs, QoS, and port security to manage traffic and secure access. Management interfaces include CLI, SNMP, and Web-based management; network standards follow IEEE 802.3 Ethernet. Power is provided by dual redundant internal power supplies and the unit is rack-mountable, designed for telecom and industrial networks requiring reliable fiber-based switching with redundancy. Common deployments include service provider and enterprise metro Ethernet environments to enable secure Layer 2 switching for access networks and aggregation layers.
