tipc bearer list

OPTIONS

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

-h, --help

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

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)

tolerance

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

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)

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 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

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.
