       tipc bearer enable [ domain DOMAIN ] [ priority PRIORITY ] media
               { { eth | ib } device DEVICE } |

               remoteport REMOTEPORT ] }

       tipc bearer disable media
               { { eth | ib } device DEVICE } |
               { udp name NAME }

       tipc bearer set { priority PRIORITY | tolerance TOLERANCE | window WINDOW } media
               { { eth | ib } device DEVICE } |
               { udp name NAME }

       tipc bearer get [ priority | tolerance | window ] media

OPTIONS

       Options (flags) that can be passed anywhere in the command chain.

       -h, --help
              Show help about last valid command. For example tipc bearer --help will show bearer
              help and tipc --help will show general help. The position of the option in the
              string is irrelevant.

DESCRIPTION

   Bearer identification
       media MEDIA
              Specifies the TIPC media type for a particular bearer to operate on.  Different
              media types have different ways of identifying a unique bearer.  For example, ib
              and eth identify a bearer with a DEVICE while udp identify a bearer with a LOCALIP
              and a NAME

              ib - Infiniband

              eth - Ethernet

              udp - User Datagram Protocol (UDP)

       name NAME
              Logical bearer identifier valid for bearers on udp media.

       device DEVICE
              Physical bearer device valid for bearers on eth and ib media.

   Bearer properties
       domain
              The addressing domain (region) in which a bearer will establish links and accept
              link establish requests.

       priority
              Default link priority inherited by all links subsequently established over a
              bearer. A single bearer can only host one link to a particular node. This means the
              default link priority for a bearer typically affects which bearer to use when
              communicating with a particular node in an multi bearer setup. For more info about
              link priority see tipc-link(8)

       tolerance
              Default link tolerance inherited by all links subsequently established over a
              bearer. For more info about link tolerance see tipc-link(8)

       window
              Default link window inherited by all links subsequently established over a bearer.
              For more info about the link window size see tipc-link(8)

   UDP bearer options
       localip LOCALIP
              Specify a local IP v4/v6 address for a udp bearer.

       localport LOCALPORT
              Specify the local port for a udp bearer. The default port 6118 is used if no port
              is specified.

       remoteip REMOTEIP
              Specify a remote IP for a udp bearer. If no remote IP is specified a udp bearer
              runs in multicast mode and tries to auto-discover its neighbours.  The multicast IP
              address is generated based on the TIPC network ID. If a remote IP is specified the
              udp bearer runs in point-to-point mode.

              Multiple remoteip addresses can be added via the bearer add command. Adding one or
              more unicast remoteip addresses to an existing udp bearer puts the bearer in
              replicast mode where IP multicast is emulated by sending multiple unicast messages
              to each configured remoteip.  When a peer sees a TIPC discovery message from an
              unknown peer the peer address is automatically added to the remoteip (replicast)
              list, thus only one side of a link needs to be manually configured. A remoteip
              address cannot be added to a multicast bearer.

       remoteport REMOTEPORT
              Specify the remote port for a udp bearer. The default port 6118 is used if no port
              is specified.

EXIT STATUS

       Exit status is 0 if command was successful or a positive integer upon failure.
