This object represents the desired Policy Profile for this
dot1dBasePort or this ifIndex.
Setting this object to any value besides zero (0) should,
if possible, immediately place this entry's dot1dBasePort
or ifIndex into the given Policy Profile.
This object and etsysPortPolicyProfileOperID may not be the
same if this object is set to a Policy (i.e. an instance of
the etsysPolicyProfileTable) which is not in an active state
or if the etsysPortPolicyProfileOperID has been set by an
underlying security protocol such as RADIUS.
