Antw: Re: partner-down still peer holds all free leases

failover peer "BackUP"                  # Name is used for Pools where Failover is implimentet
{
        primary;
        address 10.115.221.36;          # listen on Interface Address
        port 519;                       # listen on Port
        peer address 10.115.221.35;     # communicate to Address
        peer port 520;                  # communicate to Port
        max-response-delay 60;
        max-unacked-updates 10;
        mclt 1209600;
        split 128;                      # only on primary (only useful value...)
        load balance max seconds 1;
}

We actually set the mclt value to have in normal state this:
(from dhcpd.conf) This  is the length of time for which a lease may be renewed by either failover peer without contacting the other.

kind regards
Tom

IIRC, then the running server must wait for MCLT seconds after it 
entered into the partner-down state, before it will begin to manage 
leases from the partner.

That's why I'm jumping on this piece of info from omshell, what is the 
value of MCLT in the configuration?
