lso, it's best practice, if the intent is to monitor all VLANs, to not trunk all VLANs on just a single AM for monitorig, but to do so for all APs and AMs. A single AP is not scaled to listen to an entire L2 broadcasts of ALL VLAns on a large enterprise network, which can have thousands to tens of thousands of devices ARPing on all the VLANs. Best practice is to trunk all VLANs at the edge switch the AP or AM is connected to. That way all the VLANs are divided up and the AMs and APs can share the load more naturally.
