So if we have, let's say, 15 switches in the same building, that becomes a bit of a problem, and an expensive one. I'm hearing that mirroring multiple interfaces is too much for a Meraki switch to handle, so I'm not sure of the best way to see the most traffic. I doubt that putting a security appliance on each switch is financially feasible. There must be a way to capture at least a majority of the traffic. We're also looking into taps/aggregators, but I haven't had experience with those personally. In the larger buildings, we might have to just resort to passive taps, but I still need to understand the best way to configure the switches in that case.
