 Configuration
 #############
 
+.. cfgcmd:: set interfaces macsec <interface> security cipher [gcm-aes-128]
+
+  Select cipher suite used for cryptographic operations. This setting is
+  mandatory.
+
+  .. note:: gcm-aes-256 support planned once iproute2 package is updated to
+     version >=5.2.
+
+.. cfgcmd:: set interfaces macsec <interface> security encrypt
+
+  MACsec only provides authentication by default, encryption is optional. This
+  command will enable encryption for all outgoing packets.
+
+.. cfgcmd:: set interfaces macsec <interface> source-interface <physical-source>
+
+  A physical interface is required to connect this MACsec instance to. Traffic
+  leaving this interfac will now be authenticated/encrypted.
+
+
+Key Management
+--------------
+
+.. cfgcmd:: set interfaces macsec <interface> security key cak <key>
+
+  IEEE 802.1X/MACsec pre-shared key mode. This allows to configure MACsec with
+  a pre-shared key using a (CAK,CKN) pair.
+
+.. cfgcmd:: set interfaces macsec <interface> security key ckn <key>
+
+  CAK Name
+
