The output shows that the packets sent by LB can reach Device A through Device B. 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 49 , configure and schedule a DHCP operation to test the time required for LB to
obtain an IP address from the DHCP server (Device).

Configuration procedure
# Create a DHCP operation to be performed on interface GigabitEthernet 0/1.
