I can confirm 7050X series do support this feature.We're using 7050SX and
7050S, 7050S isn't supported

I have not found x-flow to have the accuracy I would like. Either there's
a loss of information due to sampling and such low-usage interfaces (or
VLANs in this case) are lost in the noise or there's information overload
due to no sampling at all.


I have seen very few platforms expose counter information about VLANs in
the same way they do regular interfaces. Some Juniper platforms, Mikrotik,
and I hear some Aristas as well.

You should be able to do that with Sflow, which they all/most support.

Also, this seems like standard Ifmib stuff, any snmp poller should be able
to handle that, from a metrics perspective .

I asked over at https://puck.nether.net/mailman/listinfo/arista-nsp a
couple weeks ago, but didn't get an answer, so I have moved to a larger
group.

I understand that some Arista switches will expose each VLAN in SNMP so I
can monitor traffic on a VLAN independently of over VLANs on that same
physical interface. Some of them don't.

Which ones do?

I prefer a solid used switch.


10G ports are fine.
