Interpreting Transport Errors

The following are possible situations you may currently ﬁnd yourself in.

Transport problem corrected.

If you have made a change that corrected your Transport problem, then

return to the Service Layer test that originally failed and try again.

Conﬁguration or other change required.

If the corrective action in the following sections require you to change a

conﬁguration parameter or make some other change, then do so and

rerun the Transport test.

operation under Transport menu.
