Configures the MACsec cipher suite on a switch port for enhanced traffic security. MACsec supports two cipher suites, the GCM-AES-128 with a maximum key length of 128 bits and the GCM-AES-256 with a maximum key length of 256 bits.
Configuring a MACsec cipher suite is optional and is not supported on all hardware platforms.
