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 estab-
lished 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 es-
tablished over a bearer. For more info about link tolerance see
tipc-link(8)
window
Default link window inherited by all links subsequently estab-
lished 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 speci-
fied a udp bearer runs in multicast mode and tries to auto-dis-
cover 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 com-
mand. Adding one or more unicast remoteip addresses to an exist-
ing udp bearer puts the bearer in replicast mode where IP multi-
cast 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.
