Hi @Naresh_Bhardwaj
Take a read through the below document
https://documentation.meraki.com/MR/Monitoring_and_Reporting/Static_IP_Assignment_on_a_Cisco_Meraki_...
Below snippet is taken from it
"If the AP is not able to reach the configured default gateway on this static assignment, it will fail back to DHCP. Please inspect the static configuration and the VLAN configuration being used on the network if this happens".
Have you tagged the correct vlan on the uplink from the switch to the AP
Note: If a VLAN is specified in the static IP configuration, management traffic from the AP will be sent out with an 802.1q tag for that VLAN. In this case it is expected that return Management traffic should also be tagged appropriately.
