Description: Describes the operational status of this FDDI serial controlled module.

insertFNB1(1) - The serial controlled module is inserted into FNB-1 and bypassed from FNB-2.

insertFNB2(2) - The serial controlled module is bypassed from FNB-1 and inserted into FNB-2.

insertFNB1FNB2(3) - The serial controlled module is inserted into both FNB-1 and FNB-2.

bypass(4) - The serial controlled module is bypassed from both FNB-1 and FNB-2.

What is ctFDDISerialOperStatus?

This value reports the actual current operational connection state of this FNB serial control module: inserted into FNB-1, FNB-2, both, or bypassed from both. An admin compares it against ctFDDISerialAdminStatus to confirm whether the module's actual state matches the administratively requested state, revealing configuration or hardware issues if they diverge. For example, if ctFDDISerialAdminStatus is set to insert on both FNBs but ctFDDISerialOperStatus still shows bypass, the admin would know the module has not yet transitioned to the desired dual-ring insertion state.
