The output shows that the packets sent by Device A can reach Device B through Device C. No packet loss
occurs during the operation. The minimum, maximum, and average round-trip times are 2, 5, and 3
milliseconds, respectively.
DHCP operation configuration example
Network requirements
As shown in Figure 39 , configure and schedule a DHCP operation to test the time required for Switch A
to obtain an IP address from the DHCP server (Switch B).
