.SH OPTIONS
Options (flags) that can be passed anywhere in the command chain.
.TP
.BR "\-h" , " --help"
Show help about last valid command. For example
.B tipc bearer --help
will show bearer help and
.B tipc --help
will show general help. The position of the option in the string is irrelevant.
.SH DESCRIPTION

.SS Bearer identification
.TP
.BI "media " MEDIA
.br
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,
.BR "ib " "and " eth
identify a bearer with a
.I DEVICE
while
.B udp
identify a bearer with a
.IR "LOCALIP " "and a " NAME

.B ib
- Infiniband
.sp
.B eth
- Ethernet
.sp
.B udp
- User Datagram Protocol (UDP)
.sp

.TP
.BI "name " NAME
.br
Logical bearer identifier valid for bearers on
.B udp
media.

.TP
.BI "device " DEVICE
.br
Physical bearer device valid for bearers on
.B eth
and
.B ib
media.

.SS Bearer properties

.TP
.B domain
.br
The addressing domain (region) in which a bearer will establish links and accept
link establish requests.

.TP
.B priority
.br
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
.BR tipc-link (8)

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

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

.SS UDP bearer options

.TP
.BI "localip " LOCALIP
.br
Specify a local IP v4/v6 address for a
.B udp
bearer.

.TP
.BI "localport " LOCALPORT
.br
Specify the local port for a
.B udp
bearer. The default port 6118 is used if no port is specified.

.TP
.BI "remoteip " REMOTEIP
.br
Specify a remote IP for a
.B udp
bearer. If no remote IP is specified a
.B 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
.B udp
bearer runs in point-to-point mode.

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

.TP
.BI "remoteport " REMOTEPORT
.br
Specify the remote port for a
.B udp
bearer. The default port 6118 is used if no port is specified.

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