Example of the debug ip udp-helper Command

Dell(conf)# debug ip udp-helper
                                 01:20:22: Pkt rcvd on TenGig 5/0 with IP DA (0xffffffff) will be sent on TenGig 5/1 TenGig 5/
                                 2 Vlan 3
                                 01:44:54: Pkt rcvd on TenGig 7/0 is handed over for DHCP processing.
                              

When using the IP helper and UDP helper on the same interface, use the debug ip dhcp command.
