Still struggling with this.
Perhaps I wasn't clear, but question #3 was about what I see in the leases file.
After the lease is expired, here's what I find in the leases file.
---
lease 10.8.20.229 {
starts 5 2020/07/17 22:42:54;
ends 5 2020/07/17 22:42:52;
tstp 5 2020/07/17 22:42:54;
tsfp 5 2020/07/17 22:42:54;
atsfp 5 2020/07/17 22:42:54;
cltt 5 2020/07/17 18:42:52;
binding state backup;
hardware ethernet 98:01:a7:ff:ff:ff;
uid "\000\000\000\000\000\000";
set remote-handle = %3;
set vendor-class-identifier = "MSFT 5.0";
}
---
The only thing that I noticed that changed after setting flags was the
set remote-handle = %3;
And I can't find any detail about what "remote-handle" is.
Does it even apply to reservations?
TIA
