Usage Guidelines

Usage Scenario

If a DHCP client cannot obtain an IP address properly, run the dhcp relay client-info command on the DHCP relay agent so that the DHCP relay agent records the information exchanged between the DHCP client and server based on the specified option code and sub-option code in DHCP packets.

To view the option code or sub-option code based on which a DHCP relay agent records DHCP packets, run the display dhcp relay client-info option configuration command.

The actual command output varies according to the device. The command output here is only an example.

# Display the option code or sub-option code based on which a DHCP relay agent records DHCP packets.
