Make Room for the “Internet of Things”

You need a network that can route both IPv4 and IPv6 without fail. The MLX Series delivers industry-leading scale for simultaneous v4 and v6 routing, with a wide range of configurations to meet every business need.

Great Power and Great Capabilities

Each new module is designed with a unique architecture that allows top-level forwarding performance no matter how many ports you add. Traffic can pass at wire speed—with no degradation in quality.

Move Seamlessly to SDN

Bring the power of “interworking” to your network with SDN. The MLX Series features Extreme’s highly differentiated hybrid-port mode, which lets you combine traditional IPv4, IPv6, and MPLS forwarding with SDN-based forwarding on the same port.
