Description
Use the dhcp relay security static command to configure a static client entry, which is the binding
between IP address, MAC address, and Layer 3 interface on the relay agent.
Use the undo dhcp relay security command to remove specified client entries from the relay agent.
No manual client entry is configured on the DHCP relay agent by default.
When using the dhcp relay security static command to bind an interface to a static client entry, make sure
that the interface is configured as a DHCP relay agent; otherwise, entry conflicts may occur.
The undo dhcp relay security interface command is used to remove all the dynamic client entries from the
interface.
