I am standing up an instance of Security Onion 2 on an Antsle One to provide detection capability and visibility on a customer's network. When I try to capture packets on my monitor interface from a span port om my Cisco switch all I see is layer 2/broadcast traffic. I found this post which references this issue: https://antsle.com/forum/topic/capturing-traffic-to-br2-interface-in-promiscuous-mode/. However when I try to run the command "emerge bridge-utils" I get "zsh: command not found: emerge" so I am unable to adjust the setageing setting with the " brctl setageing br2 0" command which is the recommended fix for this this issue. Does anyone have any ideas or workarounds for this problem?
Thanks
