Network Time Protocol Provides information to synchronize timekeeping between time servers - Dell PowerSwitch S4048T-ON | OS10 Enterprise Edition User Guide Release 10.4.2.0 - Page 583
Configuration parameters are options in the DHCP packet in type, length, value (TLV) format. To limit the number of parameters that servers must provide, hosts enter the parameters that they require and the server sends only those parameters. DHCP uses the User Datagram Protocol (UDP) as its - Dell PowerSwitch S4048T-ON | OS10 Enterprise Edition User Guide Release 10.4.2.0 - Page 584
