NAME
       ip-macsec - MACsec device configuration

SYNOPSIS
       ip  link  add  link DEVICE name NAME type macsec [ [ address <lladdr> ]
       port PORT | sci <u64> ]  [  cipher  {  default  |  gcm-aes-128  |  gcm-
       aes-256"}][" icvlen ICVLEN ] [ encrypt { on | off } ] [ send_sci { on |
       off } ] [ end_station { on | off } ] [ scb { on | off } ] [  protect  {
       on  |  off  }  ] [ replay { on | off } ] [ window WINDOW ] [ validate {
       strict | check | disabled } ] [ encodingsa SA ]

       ip macsec add DEV tx sa { 0..3 } [ OPTS ] key ID KEY
       ip macsec set DEV tx sa { 0..3 } [ OPTS ]
       ip macsec del DEV tx sa { 0..3 }

       ip macsec add DEV rx SCI [ on | off ]
       ip macsec set DEV rx SCI [ on | off ]
       ip macsec del DEV rx SCI

       ip macsec add DEV rx SCI sa { 0..3 } [ OPTS ] key ID KEY
       ip macsec set DEV rx SCI sa { 0..3 } [ OPTS ]
       ip macsec del DEV rx SCI sa { 0..3 }

       ip macsec show [ DEV ]

       OPTS := [ pn { 1..2^32-1 } ] [ on | off ]
       SCI := { sci <u64> | port PORT address <lladdr> }
       PORT := { 1..2^16-1 }

DESCRIPTION
       The ip macsec commands are used to configure transmit  secure  associa-
       tions  and  receive  secure channels and their secure associations on a
       MACsec device created with the ip link add  command  using  the  macsec
       type.

EXAMPLES
   Create a MACsec device on link eth0
       # ip link add link eth0 macsec0 type macsec port 11 encrypt on

   Configure a secure association on that device
       # ip macsec add macsec0 tx sa 0 pn 1024 on key 01 81818181818181818181818181818181

   Configure a receive channel
       # ip macsec add macsec0 rx port 1234 address c6:19:52:8f:e6:a0

   Configure a receive association
       # ip macsec add macsec0 rx port 1234 address c6:19:52:8f:e6:a0 sa 0 pn 1 on key 00 82828282828282828282828282828282

   Display MACsec configuration
       # ip macsec show

NOTES
       This  tool  can be used to configure the 802.1AE keys of the interface.
       Note that 802.1AE uses GCM-AES with a initialization  vector  (IV)  de-
       rived  from  the  packet number. The same key must not be used with the
       same IV more than once. Instead, keys must  be  frequently  regenerated
       and distibuted.  This tool is thus mostly for debugging and testing, or
       in combination with a  user-space  application  that  reconfigures  the
       keys. It is wrong to just configure the keys statically and assume them
       to work indefinitely. The suggested and standardized way for  key  man-
       agement is 802.1X-2010, which is implemented by wpa_supplicant.
