I can't get the eth.ig==0 display filter to work

I have a trace of broadcasts and a few unicast destinations. I want to filter to see only the destinations that are not broadcasts or multicasts, only unicasts.

When I filter eth.ig==0 it returns the broadcasts too. It should only return packets that match the filter. I clearly get broadcasts too.

It appear the reason is that this filter is for both source and destination address eth.ig bits.

How do I get it to filter only on what I might think should be: eth.dst.ig==0

Appreciate the help!

Bill

That works, but we really should make filters such as eth.dst.ig == 0 work.

Please file an enhancement request for this on the Wireshark Bugzilla.

Indeed, both src and dst are using the same header field definitions for lg and ig bits(which is fine) but should probably have their own src and dst specific ones as well (for all parts of the MAC address).
