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. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com
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 . -Steve On Fri, Dec 6, 2019 at 4:31 PM Mike Hammett <nanog@ics-il.net> wrote:

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. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "Steve Meuse" <smeuse@mara.org> To: "Mike Hammett" <nanog@ics-il.net> Cc: "nanog" <nanog@nanog.org> Sent: Friday, December 6, 2019 4:20:08 PM Subject: Re: Arista Switch Suggestion You should be able to do that with Sflow, which they all/most support.
