Before we combined one of our networks, the MX appliance was tracking clients by IP. When we went to combine the networks, this is the message we are getting:
"Security appliance networks tracking clients by IP addresses cannot be combined with other networks"
Also in the Address & VLANs section of the MX appliance, the option to track by IP if there is a Meraki layer 3 switch, is not available.
Why is this option, IP address, grayed out? If we track by MAC address the MX is only going to see the MAC address of the Layer 3 Switch.
