Hi,
I am experiencing a strange problem with my WS-C3560CG-8PC and a Meraki MV device.
Set-up: 1 x WS-C3560CG-8PC, enabled for routing, service dhcp enabled, DHCP server is the switch and I am looking to relay the information to a 3P NAC solution.
When I connect a standard laptop to the switch the device gets an IP address from the switch and the DHCP request is relayed to my 3P NAC solution. I am debugging DHCP on the switch and see the request being forwarded to the 3P NAC solution IP as per the interface configuration. However when I connect the Meraki camera I do not see the request being forwarded. If I connect the camera to a HPE/Aruba switch and move the configuration to this device it works. So it looks like something specific on the switch. Any idea what might be causing this, the switch configuration is very basic and seems to work for everything aside from this camera.
Below is a capture from the switch for a working device and after this the camera.
