FAILOVER IN A MEDIA ACCESS CONTROL SECURITY CAPABALE DEVICE

Examples disclosed herein relate to providing a failover in a MACsec capable device. In an example, a determination may be made on a Media Access Control (MAC) Security (MACsec) capable device, whether a primary management engine that manages a protocol related to MACsec standard on the MACsec capable device has failed. In response to a determination that the primary management engine has failed, a secondary management engine in the MACsec capable device may create a Connectivity Association (CA) between the MACsec capable device and a peer MACsec capable device by performing an IEEE 802.1X re-authentication with the peer MACsec capable device within MACsec Key Agreement (MKA) lifetime. The MKA lifetime may refer to a period during which no MACsec Key Agreement Protocol Data Unit (MKPDU) is received by the peer MACsec capable device from the MACsec capable device.
