Altostratustcpdump 'h' noise amplifier
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 traffic. Could anyone verify this?
tcpdump -nnei tmm:h host 127.1.1.2 and host 127.1.1.254
tcpdump -nnei VLAN_HA:h host 1.1.1.1 and port 6699
Is there any official doc related?
KR, Dario.

Notes about the wireshark plugin
As of Wireshark 2.6.0 (rel. 4/24/2018) the 1.11 version of the f5ethtrailer dissector is included as a built-in. It is no longer necessasary to use the plugin do decode f5ethtrailer information.
It is disabled by default. To enable it, from the menu select "Anyalyze" : "Enabled Protocols...". Then search for f5ethtrailer and enable the dissector. https://www.wireshark.org/news/20180424.html
DarioGB_339840Hello Imiestc, thanks for your response ;-).
Actually, I'm asking for 'h' option (not for 'nnn'), which is not included in this KB.
Do you know any other which talks about 'h' option?
KR, Dario.

Just to clarify. With "noise amplifier" i mean "noise amplitude".
Any help?
