problem with dhcp failover

[Julie Xu]

Hi,

I have configured our dhcp pair as failover, as below:
failover peer "xxx" {
    primary;
    address 10.10.10.10;
    peer address 10.10.10.11;
    port xxx;
    peer port xxx;
    max-response-delay 60;
    max-unacked-updates 10;
    mclt 300;
    split 128;
    load balance max seconds 3;
    auto-partner-down 0;
    max-lease-misbalance 15;
    max-lease-ownership 10;
    min-balance 60;
    max-balance 3600;
}

It is working good if both dhcp servers online. However, if one of the server is offline, than half of my ip addresses can not be renewed.

How can I troubleshoot this issue? What possible reasons can cause this issue?

Any comments will be appreciated

Thanks in advance

Julie
