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.
