Therefore, the largest bundle that can be sent via this convergence layer is limited to just under the link's \s-1MTU \s0(typically 1500 bytes). .PP The convergence layer input task is spawned automatically by \fBbpadmin\fR in response to the 's' (\s-1START\s0) 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 \*(L"dccp\*(R" convergence layer protocol is added to the \s-1BP\s0 database. The convergence layer input task is terminated by \fBbpadmin\fR in response to an 'x' (\s-1STOP\s0) command. \fBdccpcli\fR can also be spawned and terminated in response to \s-1START\s0 and \s-1STOP\s0 commands that pertain specifically to the \s-1DCCP\s0 convergence layer protocol. .SH "EXIT STATUS" .IX Header "EXIT STATUS" .ie n .IP """0""" 4 .el .IP "``0''" 4 .IX Item "0" \&\fBdccpcli\fR terminated normally, for reasons noted in the \fBion.log\fR file.
