Dynamic Host Configuration Protocol (DHCP) relay
DHCP and DHCP relay errors are often on the client-side of the communication. In the situation
where the DHCP server is not on the same subnet as the client, the DHCP relay configuration
may be at fault. If the DHCP snooping application is enabled, then problems may occur if this
is improperly configured. For example, the ports that provide connection to the network core
or DHCP server are not set as trusted for DHCP snooping.
