.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.

.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.
