A device that operates simultaneously at more than one of these layers is known as a multilayer switch.

The RS family of products were flow-based multilayer switches.

Switches that additionally process data at the network layer (layer 3) and above are often called layer-3 switches or multilayer switches.

Load balancing is usually provided by dedicated software or hardware, such as a multilayer switch or a Domain Name System server Process.

Multilayer switch: a switch which, in addition to switching on OSI layer 2, provides functionality at higher protocol layers.

All the products were multilayer switches (or switch-routers) and specialized in MPLS VPNs.

Rogue DHCP servers can be stopped by means of intrusion detection systems with appropriate signatures, as well as by some multilayer switches, which can be configured to drop the packets.

A multilayer switch (MLS) is a computer networking device that switches on OSI layer 2 like an ordinary network switch and provides extra functions on higher OSI layers.

Application delivery uses one or more layer 4-7 switches, also known as a web switch, content switch, or multilayer switch to intelligently distribute traffic to a pool, also known as a cluster or farm, of servers.

Server-load balancing uses one or more techniques including service-based (global load balancing) or hardware-based, i.e. layer 4-7 switches, also known as a web switch, content switch, or multilayer switch to share traffic among a number of servers or web caches.

Arista's devices are multilayer switches, they all support a range of layer 3 protocols, such as IGMP, VRRP, RIP, BGP, OSPF, and, once the standard is ratified, TRILL.

Multi-layer switches are capable of routing based on layer 3 addressing or additional logical levels.

The Broadcom based multi-layer switches offer a wide range of layer-2 and layer-3 options, and new features are added all the time.

The multi-layer switches with a model-numer 6200 and higher included Broadcom hardware and software.

Although CEF is a Cisco proprietary protocol other vendors of multi-layer switches or high-capacity routers offer a similar functionality where layer-3 switching or routing is done in hardware (in an ASIC) instead of by software and the (central) CPU).
