OPTIONS

35       Options (flags) that can be passed anywhere in the command chain.
36
37       -h, --help
38              Show help about last valid command. For example tipc bearer
39              --help will show bearer help and tipc --help will show general
40              help. The position of the option in the string is irrelevant.

DESCRIPTION

43   Bearer identification
44       media MEDIA
45              Specifies the TIPC media type for a particular bearer to operate
46              on.  Different media types have different ways of identifying a
47              unique bearer.  For example, ib and eth identify a bearer with a
48              DEVICE while udp identify a bearer with a LOCALIP and a NAME
49
50              ib - Infiniband
51
52              eth - Ethernet
53
54              udp - User Datagram Protocol (UDP)
55
56
57
58       name NAME
59              Logical bearer identifier valid for bearers on udp media.
60
61
62       device DEVICE
63              Physical bearer device valid for bearers on eth and ib media.
64
65
66   Bearer properties
67       domain
68              The addressing domain (region) in which a bearer will establish
69              links and accept link establish requests.
70
71
72       priority
73              Default link priority inherited by all links subsequently estab‐
74              lished over a bearer. A single bearer can only host one link to
75              a particular node. This means the default link priority for a
76              bearer typically affects which bearer to use when communicating
77              with a particular node in an multi bearer setup. For more info
78              about link priority see tipc-link(8)
79
80
81       tolerance
82              Default link tolerance inherited by all links subsequently
83              established over a bearer. For more info about link tolerance
84              see tipc-link(8)
85
86
87       window
88              Default link window inherited by all links subsequently estab‐
89              lished over a bearer. For more info about the link window size
90              see tipc-link(8)

92
93   UDP bearer options
94       localip LOCALIP
95              Specify a local IP v4/v6 address for a udp bearer.
96
97
98       localport LOCALPORT
99              Specify the local port for a udp bearer. The default port 6118
100              is used if no port is specified.
101
102
103       remoteip REMOTEIP
104              Specify a remote IP for a udp bearer. If no remote IP is speci‐
105              fied a udp bearer runs in multicast mode and tries to auto-dis‐
106              cover its neighbours.  The multicast IP address is generated
107              based on the TIPC network ID. If a remote IP is specified the
108              udp bearer runs in point-to-point mode.
109
110              Multiple remoteip addresses can be added via the bearer add com‐
111              mand. Adding one or more unicast remoteip addresses to an exist‐
112              ing udp bearer puts the bearer in replicast mode where IP multi‐
113              cast is emulated by sending multiple unicast messages to each
114              configured remoteip.  When a peer sees a TIPC discovery message
115              from an unknown peer the peer address is automatically added to
116              the remoteip (replicast) list, thus only one side of a link
117              needs to be manually configured. A remoteip address cannot be
118              added to a multicast bearer.
119
120
121       remoteport REMOTEPORT
122              Specify the remote port for a udp bearer. The default port 6118
123              is used if no port is specified.
124
125

EXIT STATUS

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