Layer 3 Interface (SVI) Caveats Switch Management IP and Layer 3 Interfaces (SVIs) The management IP is treated entirely different from the SVIs and must be a different IP address. It can be placed on a routed or non-routed VLAN (e.g.: a management VLAN independent from client traffic). Traffic from the management IP address to the Cisco Meraki Cloud Controller will not use the layer 3 routing settings; instead, it will be using its configured default gateway. Therefore, it is important that the IP address, VLAN, and default gateway configured in your switch management IP can still provide connectivity to the internet independently from the switch's own L3 routing settings. The Switch (or Stack) management IP configuration cannot have Gateway address defined as one of its own SVI address when it is performing Layer 3 routing. It will not be able to check in using the assigned management IP when the gateway is pointed to itself. For example, if 192.168.1.1 is one of the L3 interfaces (SVI) on a switch (or stack), you cannot have 192.168.1.1 as the gateway for its management IP (Switching > Switches > LAN IP).
