Description
Use the dhcp relay security refresh enable command to enable the DHCP relay agent to periodically
refresh dynamic client entries.
Use the undo dhcp relay security refresh enable command to disable periodic refresh of dynamic
client entries.
By default, the DHCP relay agent is enabled to periodically refresh dynamic client entries.
Note that:
If you disable the DHCP relay agent from periodically refreshing dynamic client entries, such entries do
not age automatically. Therefore, if a client relinquishes its IP address, you need to manually remove
the corresponding dynamic client entry on the DHCP relay agent.
