Using multiple client classes with ISC DHCPd
Since the internet is lacking examples of how to use multiple classes with a single pool here is one:
class "mac-filtered-clients" { match binary-to-ascii (16, 8, ":", substring(hardware, 1, 6)); } subclass "mac-filtered-clients" "50:7b:00:00:00:00"; # some cool host! class "J-client" { spawn with option agent.circuit-id; match if (substring(option agent.circuit-id, 30, 9) = "foo-bar"); lease limit 1; } subnet 192.168.0.0 255.255.0.0 { pool { range 192.168.0.10 192.168.0.150; allow members of "J-client"; allow members of "mac-filtered-clients"; } }
This isn't very special compared to a setup with just a single class but it can be confusing since debugging classes is a pita.. One pitfall I did run into was using the byte representation of the mac-addresses (without the quotes) and using match hardware;
. The example above works for me (tm).
