tcpdump "-i any" option unavailable in AIX tcpdump

In tcpdump man page (https://www.tcpdump.org/tcpdump_man.html), we have option to provide "any" as interface (with -i flag), which allows us to listen to all available interface. While in AIX tcpdump(https://www.ibm.com/support/knowledgecenter/en/ssw_aix_72/com.ibm.aix.cmds5/tcpdump.htm) we don't have any such option.

I was testing sctp feature, where i need to listen to multiple interfaces at a time since sometimes i need to perform sctp failover, which will transfer all the traffic from one interface to another interface.

Can we have "-i any" or anything similar which will allow us to listen to multiple interfaces in one go?

    "tcpdump" is not the "native" promiscuous tool. That is /usr/sbin/iptrace.

    from memory, about 15 to 20 years ago there was a different "extension" that was used to capture packets, depending on which program was used. "iptrace" has always, by default worked as "-i any" when no interface was supplied. On AIX, tcpdump has always looked for the "lowest ordered named interface", e.g., en1 and en2 are defined - tcpdump watches en1.

    So, for your particular issue you could consider using "iptrace" to capture and "ipreport" to analyze.

    Hope this helps!
