Whenever a transport user makes a connection to a user process on the

same node, all outbound packets on this connection are turned around

at the NI level and passed back up through the protocol stack to the

destination user. This screen supplies information necessary for this

operation, performed by the loopback NI.

Press the

[Save Data] function key to transfer the data displayed on the

screen to the conﬁguration ﬁle you are creating or updating. Verify that

the data record has been created by checking that the Data ﬂag is set

to Y.
