**tipc bearer list**

# [OPTIONS](#OPTIONS)

Options (flags) that can be passed anywhere in the command chain.

[**-h**, **--help**](#h)

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](#DESCRIPTION)

## [Bearer identification](#Bearer_identification)

[**media 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** identifies a bearer with a *LOCALIP* and a *NAME*

**ib** - Infiniband

**eth** - Ethernet

**udp** - User Datagram Protocol (UDP)

[**name NAME**](#name)

Logical bearer identifier valid for bearers on **udp** media.

[**device DEVICE**](#device)

Physical bearer device valid for bearers on **eth** and **ib** media.

## [Bearer properties](#Bearer_properties)

[**domain**](#domain)

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

[**priority**](#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 a multi-bearer setup. For more info about link priority see [**tipc-link**(8)](/man/os/iproute2/tipc-link.8)

[**tolerance**](#tolerance)

Default link tolerance inherited by all links subsequently established over a bearer. For more info about link tolerance see [**tipc-link**(8)](/man/os/iproute2/tipc-link.8)

[**window**](#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)](/man/os/iproute2/tipc-link.8)

## [UDP bearer options](#UDP_bearer_options)

[**localip LOCALIP**](#localip)

Specify a local IPv4/IPv6 address for a **udp** bearer.

[**localport LOCALPORT**](#localport)

Specify the local port for a **udp** bearer. The default port 6118 is used if no port is specified.

[**remoteip 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**](#remoteport)

Specify the remote port for a **udp** bearer. The default port 6118 is used if no port is specified.

# [EXIT STATUS](#EXIT_STATUS)

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