FOS version 8.2.2 and earlier:
The user must use SMI agent integrated in either Professional Plus or Enterprise edition of Brocade Network Advisor or Connectrix Manager Converged Network Edition (CMCNE) to manage a switch running Fabric OS 8.2.2 or earlier using the SMI-S interface.
FOS version 8.2.2a and later:
The host SMI-S agents cannot be used to manage switches running Fabric OS 8.2.2a. Brocade has confirmed this, and it is documented in the release notes. That SMI agents are not supported is clear on the switches.
