This read-only object reports the erroneous-SDU-delivery setting actually negotiated with the network for the profile's active session. An admin checks this to confirm whether the network will actually deliver corrupted SDUs to the device or filter them out, as negotiated, which affects how the application should be expected to handle its own error detection. For example, if a data-integrity-sensitive application starts receiving occasional bad packets, the admin would check this negotiated setting to see whether the network was actually permitted to deliver erroneous SDUs for this session.
