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.
