Abstract: Examples disclosed herein relate to security actions that can be taken at a network appliance based on a received copy of a neighbor discovery packet. The neighbor discovery packet copy is received on a control plane of a network that originated at a port on a data plane of the network. The neighbor discovery packet copy includes identification information including an internet protocol address, a media access control address, and information about the port. The identification information is compared to a binding state table to determine that the internet protocol address and the media access control address match the binding state table, but the port does not match a previous port on the binding state table for the internet protocol address. A security action is performed.
