Devices, systems, methods, and processes for data plane redundancy management in network devices are described herein. A linecard in a network device may classify a plurality of packets into a first category or a second category based on whether a packet is a control packet or a data packet. The linecard may transmit all control packets and data packets to an active data plane. The linecard may selectively transmit the control packets and a sampled subset of the data packets to a standby data plane. Thus, the standby data plane is equipped with dynamic information of network using the control packets and Media Access Control addresses using the sampled subset of the data packets. When a failure is detected in the active data plane, the linecard starts transmitting all the data packets also to the standby data plane and starts accepting processed packets from the standby data plane for forwarding.

A system for implementing a multiplane network comprises a network device including a plurality of switches for routing traffic to an endpoint through a network of other switches. Each switch in the plurality of switches corresponds to a different plane of the multiplane network. The system includes one or more circuits that manages the plurality of switches as a single logical entity.
