The other type of entries are usually automatically created by DHCP. You can modify it to match the other types of entries if you wish to reserve your current automatically allocated ones. We use reservations for all our printers and switches. They were all originally entered manually with their MAC address and chosen IP. These are what should be selected with the script. I deliberately excluded all the IPs that had been automatically assigned by the DHCP server to PCs and then allowed them to be reallocated by the DHCP server. If you wish to convert automatically assigned IPs to reservations on the new system change the line [perl light="1"]next unless ($type == 8);[/perl] to [perl light="1"]next unless ($type == 8 or $type == 2);[/perl] The aim of $type == 8 is to only select DHCP reservations.

I don't get any errors but the output file is blank. Any ideas? I’ve tried running the script against my DHCP3TAB file. I don’t get any errors but the output file is blank. Any ideas?
