Usage guidelines
Client information is recorded only when the DHCP relay agent is configured on the gateway of
DHCP clients. A relay entry contains information about a client such as the client's IP and MAC
addresses.
Disabling the recording of client information deletes all recorded relay entries.
Examples
# Enable the recording of relay entries on the relay agent.

[Sysname] dhcp relay client-information record
