Tcpdump: not able to dump while specifying interface


With fimware 3.5.6 on a ePMP 1000 SM 5 Ghz, I not able to dump traffic and indicate the interface through the -i option.

tcpdump "-i br-lan"

work fine but not

tcpdump dump "-i br-lan"

Every other options I tryed with dump enabled didn't return any error except -i. Any way to work around this or it's a bug ?


Could you please try with the latest 4.4.3?

Thank you.
