When the 

 command is executed in Ethernet 

interface view, it takes effect only for the address pool of that interface. It takes 
effect for all address pools when used in other views.

DHCP server test whether IP addresses are in conflict by sending ping packets, 
while DHCP client do it by sending ARP packets. 

In a typical DHCP application network, one DHCP server will support many DHCP 
clients (for example PCs or laptops). See Figure 103.

DHCP client is in fact a concept at interface level. If a host provides multiple 
Ethernet interfaces, then each interface can be configured as an independent 
DHCP client. 

It is simpler to implement DHCP client attributes at a router than to implement at a 
host.
