Hi there,

Currently where I work we have customers with static IP addresses and dynamic IP addresses.

We need to implement cable source verify on our CMTSs. I have no issue getting this to work with latest version of ICS DHCP but I a stumped at how to enable this going forward with static IPs. Currently I have host entries for static IPs but obviously no lease is written to /var/lib/dhcpd/dhcpd.leases for these the problem is then that LEASEQUERY isn't going to work for static IP customers. I have tried editing /var/lib/dhcpd/dhcpd.leases sometimes it works sometimes it doesn't so this won't be a reliable method.

So my question is as follows:

Is it possible to configure the ICS DHCP server to inform the CMTS that a lease exists for a certain MAC address even if no such lease actually exists.

Look forward to some suggestions.

Q.

Have you tried adding dhcp reservations for your static IP customers ? This may not help, if all your customers equipment was configured to use dhcp, then for a static customer you just add a reservation, but if it's been configured manually you may be stuck.

The configuration could be like this.

subnet XX.169.176.0 netmask 255.255.255.248 {
option routers XX.169.176.1;
range XX.169.176.10 XX.169.176.200;
host donaldduck {
hardware ethernet 00:11:22:33:44:55;
fixed-address XX.169.176.4;
}
}
