Abstract

In some examples, a system includes a router device and a first adapter device in communication with the router device. The first adapter device includes processing circuitry configured to: communicate with the router device, wherein the router device is incapable of communicating in accordance with the MACsec protocol. The processing circuitry is further configured to establish an encrypted connection in accordance with the MACsec protocol between the first adapter device and a remote device, determine that the encrypted connection is offline, and output a message to the router device that the encrypted connection is offline. The router device is configured to communicate with the remote device via a second adapter device configured to communicate in accordance with the MACsec protocol and bypass the first adapter device.
