Hi Girish,

As per protocol DHCP Server will not send any DHCP message to client in case adminitrator manually clears the DHCP bindings.

DHCP clients will get re-initialized automatically after it's renew requests will not get responded. It might not be great idea to force the client to release the IP address before the lease time gets expired.


Regards,
Gaurav Halwasia

Subject: [dhcwg] DHCP server deleting the IP-MAC binding entry

Hello Experts,

I read RFC 2131 and have the following query -

If the administrator manually deletes the dhcp IP-MAC binding entry
from the DHCP server database, is there any DHCP message generated for
it? I think it is not generated. Please let me know if we are missing
anything. Will it not be a good idea to generate a new DHCP message
which can flush the state of DHCP clients/DHCP Snooping switches and
re-initialize their state machines?

Please let me know your thoughts.

Thanks,
Girish
