Is there a way to get stats for an interface's IPv4 and IPv6 traffic from the command line?

[ChrisJenk]

I'd like to be able to get stats (bytes sent, bytes received) for a specific interface, broken out by IPv4 and IPv6, ideally from the command line. Is thsi possible?

I looked at netstat -I <ifname> -b but the counters don't tie up at all, other than for the <Link#n> stats, which of course include IPv4, IPv6 and other stuff, so not suitable for my needs.

Try for example:

[23.09.1-RELEASE][admin@fw1.stevew.lan]/root: pfctl -vvsI -i mvneta0
mvneta0

	In4/Pass:    [ Packets: 84261748           Bytes: 6404497380         ]
	In4/Block:   [ Packets: 2473281            Bytes: 85666362           ]
	Out4/Pass:   [ Packets: 116590050          Bytes: 38322442341        ]
	Out4/Block:  [ Packets: 0                  Bytes: 0                  ]
	In6/Pass:    [ Packets: 2472               Bytes: 180432             ]
	In6/Block:   [ Packets: 120773             Bytes: 14138739           ]
	Out6/Pass:   [ Packets: 2651156            Bytes: 1375467130         ]
	Out6/Block:  [ Packets: 0                  Bytes: 0                  ]

Of course that only works for traffic pf sees.

@stephenw10 Thanks! I think this may work for what I need. I will experiment...
