Hi,
I am using The Cisco SG220-26P Switch and i am unable to connect a device on a local DHCP server run on a RPI. If I go through a TP-link switch i can get the DHCP server to give out IP addresses to my devices but on this Cisco switch The devices are unable to keep a connection and send DHCPRELASE packets my device is trying to get 10.0.0.6 and the server is 10.0.0.1

Has anyone had this problem with the Cisco switch before and is there a work around or solution?
