Hi
I am using the isc dhcp in standalone and it is working fine with that
mode, I added the dhcp failover to my existing setup which caused the issue
to my setup
The server is in partner down state for so long time which made me panic.
How can I reduce this time and make them in to normal normal state
FYI: I did some reading and found one param *max-unacked-updates *which was
configured to 10 when i tried for the first time thought it would be the
cause and I increased its value to 5000 because my config contains nearly
800 subnets data which is large but no luck
Does any one face same issue while adding the failover or any idea or
suggestion how to decrease the time taking to recover the failover states
into normal normal
*on Primary state changes*
cat dhcpd.leases | egrep "my state|partner state"
my state partner-down at 5 2019/11/29 06:23:00;

on Primary Server
========================================
failover peer "peer5" {
primary;
address YYY.YYY.YY.YYY;
port 647;
peer address YYY.YYY.YY.YYY;
peer port 647;
max-response-delay 30;
max-unacked-updates 5000;
load balance max seconds 3;
mclt 1800;
split 128;
}
on failover server
==========================================
failover peer "peer5" {
secondary;
address YYY.YYY.YY.YYY;
port 647;
peer address YYY.YYY.YY.YYY;
peer port 647;
max-response-delay 30;
max-unacked-updates 5000;
load balance max seconds 3;
}
It took nearly 30 minutes which makes issue for my environment, Do we have
any tunable parameters
Thanks in Advance

Hi ,
I have the host reservation data in the configuration file and it is
working fine, the host is getting the same IP which has been configured in
the conf file But I don't see the lease entry of the host IP in the
lease files, Does the ISC dhcpd doesn't store the lease data of the host
entries in the lease file?
if not do we have a way to get the info of active hosts list from the
specified DHCP server?
Thanks in Advance
