We are using CNR with multiple scopes to provide ip addressing for both computers and IPTV set top boxes. The STB's require boot params in dhcp option-131 and option-240. I have set up a client-class-policy that contains the two options and when I set up a client with an exact mac address, then the information is provided correctly.
The problem is we have hundreds of STB's. How do I get CNR to generalize the client mac address to just the first 3 bytes?
I have tried creating a client with 00:00:00 for the last three bytes and then altering the dhcp-client-identifier to match, but it doesn't work.
The docs state that you can create a client-lookup-id expression but shows no examples.
