DHCP server lease-script is not called on renew

RouterOS General
1

Hello, I am running RouterOS 6.48.3 on CCR1009
I have a DHCP server running with a lease script.

From a Windows client cmd prompt, if I execute

ipconfig /release
ipconfig /renew

the script is executed twice. First with $leaseBound set to 0, then with $leaseBound set to 1, as expected. All is well.

However, if I execute only the renew on the Windows client

ipconfig /renew

the script is not called at all. I can see in the DHCP leases, that the lease expiration time of the Windows client was reset, so it did talk to the DHCP server and said “hello…”.
Same thing happens, if I reboot the Windows client. Expiration date is reset, lease script is not called.

So here is the question: Is this expected behavior, or is this a bug in RouterOS, which I should report?
Or is there some option, where I can ask RouterOS to execute the script on a renew?

This would be a simple lease-script used for testing:

:log info message="$leaseBound $leaseServerName: $leaseActMAC -> $leaseActIP"

Thank you.

EDIT:
I forgot to mention, the Windows client has a static lease. Not sure, if this makes any difference.

static, or not, not mind

renew = the same confirmed, the lease is not created or deleted, as expected nothing change, except “lifetime”
release = end-of-use, the lease will be dropped and this trig the event

all exactly what is expected.

Good to know, thank you!
