bs_module_do_precond:No preconditioning provided for module on port 2/2.4

Both messages here are benign. The first (does not support DDM) is just a statement that the BigIP software does not currently support DDM (digital diagnostics monitoring). See sol6097 for further information on that.

The second message regarding 'No preconditioning' is meaningless on 40gbps ports. It is only significant for 100gbps. We have a bug ID 589481 in the system to get this changed to informational, rather than err, and to only display it at all for ports that require preconditioning.

The QSFP ports work in two modes, either bundled or not. This has nothing to do with LACP bundling, but refers to whether the interface is treated as 4 x 10 gb ports, or 1 x 40gbps. Although there is only one physical port present, the network card driver presents it to the operating system as either 4 x 10gbps ports, or 1 x 40 port.
