•RMONPacketCapture/FilterSamplingandPortMirroringcannotbe enab ledonthesame
interfaceconcurrently.
•Youcancaptureatotalof100packetsonaninterface,nomoreandnoless.
–Thecapturedframeswillbeasclosetosequentialasthehardwarewillallow.
–Onlyoneinterfacecanbeconfiguredfor
capturingatatime.
–Once100frameshavebeencapturedbythehardware,theapplicationwillstopwithout
manualintervention.
•AsdescribedintheMIB,thefilterisonlyappliedaftertheframeiscaptured,thusonlya
subsetoftheframescapturedwillbeavailablefordisplay.
•Thereisonlyone
