Hi!
No, SNMP is not the way to go. I can't think of any device that can be
ordered to renew the IP address via an SNMP command. The two are simply
not that tightly related.
Clients generally renew the DHCP lease after half the lease time
assigned by the DHCP server. If that renewal fails, the client tries to
renew in half the remaining lease time and this process is repeated over
and over again until the lease time expires. The client then attempts a
DHCP DISCOVER. There are different approaches to this, but this is the
most common one. I don't know of any way to force the DHCP client to
renew the lease apart from CLI commands like Windows "ipconfig /renew"
and various Linux methods. If you need the clients to get a new address
from the DHCP server, you simply have to wait until the lease time expires.

Hi there,
I'm new to SNMP implementations, so please help me asking questions
"the right way" if needed.
After a DHCP server boots up, how can it send such a command (DHCP
leases renew) to network nodes?
Is SNMP the right way to do this?
Thanks in advance,
Fabio
