NAME¶
ltpcli - LTP-based BP convergence layer input task
SYNOPSIS¶
ltpcli local_node_nbr
DESCRIPTION¶
ltpcli is a background "daemon" task that receives LTP data
transmission blocks, extracts bundles from the received blocks, and passes
them to the bundle protocol agent on the local ION node.
ltpcli is spawned automatically by bpadmin in
response to the 's' (START) command that starts operation of the Bundle
Protocol; the text of the command that is used to spawn the task must be
provided at the time the "ltp" convergence layer protocol is added
to the BP database. The convergence layer input task is terminated by
bpadmin in response to an 'x' (STOP) command. ltpcli can also
be spawned and terminated in response to START and STOP commands that
pertain specifically to the LTP convergence layer protocol.
EXIT STATUS¶
- "0"
- ltpcli terminated normally, for reasons noted in the ion.log
file. If this termination was not commanded, investigate and solve the
problem identified in the log file and use bpadmin to restart
ltpcli.
- "1"
- ltpcli terminated abnormally, for reasons noted in the
ion.log file. Investigate and solve the problem identified in the
log file, then use bpadmin to restart ltpcli.
FILES¶
No configuration files are needed.
ENVIRONMENT¶
No environment variables apply.
DIAGNOSTICS¶
The following diagnostics may be issued to the ion.log log file:
- ltpcli can't attach to BP.
- bpadmin has not yet initialized Bundle Protocol operations.
- No such ltp duct.
- No LTP induct matching local_node_nbr has been added to the BP
database. Use bpadmin to stop the LTP convergence-layer protocol,
add the induct, and then restart the LTP protocol.
- CLI task is already started for this duct.
- Redundant initiation of ltpcli.
- ltpcli can't initialize LTP.
- ltpadmin has not yet initialized LTP operations.
- ltpcli can't open client access.
- Another task has already opened the client service for BP over LTP.
- ltpcli can't create receiver thread
- Operating system error. Check errtext, correct problem, and restart
LTP.
