|*cphaprob -ia list*
|Show detailed information on the failed __pnote__/Critical Device of this member. List of  pnotes enabled by default (differs by version/model so not a reference): _Interface Active Check_, _Recovery Delay_ , _CoreXL Configuration_, _Fullsync_, _Policy/filter_, _routed_, _fwd_, _cphad_, _init_, _cvpnd_.
