Cflowd interface, where all traffic entering a given port will be subjected to sampling as
the configured sampling rate
Cflowd interface plus the definition of IP filters which specify an action of interface-
disable-sample, in which traffic that matches these filter entries will not be subject to
cflowd sampling.
Cflowd ACL, where IP filters must be created with entries containing the action filter-
sampled. In this mode only traffic matching these filter entries will be subject to the
cflowd sampling process.
