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)](https://www.chedong.com/phpMan.php/man/link/8/markdown) ### tolerance Default link tolerance inherited by all links subsequently established over a bearer. For more info about link tolerance see [**tipc-link**(8)](https://www.chedong.com/phpMan.php/man/tipc-link/8/markdown) ### 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)](https://www.chedong.com/phpMan.php/man/tipc-link/8/markdown) ### 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 con‐ figured **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. ## SEE ALSO [**tipc**(8)](https://www.chedong.com/phpMan.php/man/tipc/8/markdown), [**tipc-link**(8)](https://www.chedong.com/phpMan.php/man/tipc-link/8/markdown), [**tipc-media**(8)](https://www.chedong.com/phpMan.php/man/tipc-media/8/markdown), [**tipc-nametable**(8)](https://www.chedong.com/phpMan.php/man/tipc-nametable/8/markdown), [**tipc-node**(8)](https://www.chedong.com/phpMan.php/man/tipc-node/8/markdown), [**tipc-peer**(8)](https://www.chedong.com/phpMan.php/man/tipc-peer/8/markdown), **tipc-** [**socket**(8)](https://www.chedong.com/phpMan.php/man/socket/8/markdown) ## REPORTING BUGS Report any bugs to the Network Developers mailing list **<>** where the de‐ velopment and maintenance is primarily done.
