Abstract
An intelligent electronic device (IED) of an electric power distribution system includes processing circuitry and a memory having instructions. The instructions, when executed by the processing circuitry, are configured to cause the processing circuitry to determine establishment of setup criteria to operate in a passive mode, operate in the passive mode to communicate data without initiation of a media access control security key agreement (MKA) protocol in response to determination of the establishment of the setup criteria, receive activation data during operation in the passive mode, the activation data being indicative that a media access control security (MACsec) communication link is to be established, and operate in an active mode in response to receipt of the activation data to initiate the MKA protocol to establish the MACsec communication link.
