Has anyone had issues with the UC360 - The unit was working and had received it's DHCP from the network (DHCP is disabled on the MCD ISS Controller). The next morning the customer noticed that the unit was in DHCP Discovery mode. In our testing of the unit, the LLDP was turned "off" on the network side, but it was "on" as to UC360 settings. The technician had them turn "off" the LLDP on the UC360 then they rebooted the unit and it worked fine. The customer's IT department then went and turned LLDP "on" at the network side, and then the technician had them reset the LLDP on the UC360 settings to be "on". Would the LLDP settings of the unit/network mismatch cause the unit to lose connectivity to the network?
 
It depends on what the network is doing with the LLDP data received from the device, but it's possible. LLDP can be used to assign VLAN membership, which could cause a device to lose connectivity to its assigned VLAN when LLDP is enabled/disabled on the network side.
