Does anyone know the definition of 'h' noise amplifier in tcpdump?
It's possible to use this amplifier when I sniff TMM traffic or CMI traffic, so I think it's just to sniff internal processes traf...

CirrusFrom K13637 "The extra TMM information can only be captured when the interface on which tcpdump is listening is a Virtual Local Area Network (VLAN)." E.G "vlan:noiseamplitude"
So tcpdump -nnei tmm:h will fail with tcpdump: Ingress/egress modifier not supported on this interface.
In regards of the vlan:h option here is what man tcpdump on the F5 CLI says
h = Capture only traffic destined for the Linux host.
