[DHCP] RE: Determining request

[Randall C Grimshaw]

With this information I am going to join with Matt in suggesting the use of vlans to define a separate subnet.

    Those access points are LinkSys WAP54G - we have two of them.

    Here's a class/group section from our dhcpd.conf file (there are 
several, one for each department):

    --------------------
    ##
    ## Customer Service: 61 - 70
    ##
    class "customer_service" {
        match pick-first-value (option dhcp-client-identifier, hardware);
    }

    group {
        ddns-hostname = pick (option host-name, 
concat("dhcp-",binary-to-ascii(16,8,"-",substring(hardware,1,6))));
        use-host-decl-names on;
        host docucolor_pc       { hardware ethernet 00:11:11:04:DA:69;
                                  ddns-hostname cs_docucolor_pc; }
        host bistro_mac         { hardware ethernet 00:07:93:53:FE:58;
                                  ddns-hostname bistro_mac; }
    }

    subclass "customer_service" 1:00:11:11:04:DA:69;
    subclass "customer_service" 1:00:07:93:53:FE:58;

    ##
    ## Wireless: 161 - 180
    ##
    class "wireless" {
        match pick-first-value (option dhcp-client-identifier, hardware);
    }
    group {
        ddns-hostname = pick (option host-name, 
concat("dhcp-",binary-to-ascii(16,8,"-",substring(hardware,1,6))));
        use-host-decl-names on;
        host wireless_front     { hardware ethernet 00:1A:70:34:56:6C;
                                  ddns-hostname front-wireless; }
        host wireless_rear      { hardware ethernet 00:18:F9:32:91:AE;
                                  ddns-hostname rear-wireless; }
    }
    subclass "wireless" 1:00:1A:70:34:56:6C;
    subclass "wireless" 1:00:18:F9:32:91:AE;

    ... other class/group definitions ...


    subnet 192.168.11.0 netmask 255.255.255.0 {
        # Customer Service Group
        pool {
                allow members of "customer_service";
                deny unknown-clients;
                range 192.168.11.61 192.168.11.70;
        }
        # Wireless Group
        pool {
                allow members of "wireless";
                allow unknown-clients;
                range 192.168.11.161 192.168.11.180;
        }
    ... more pool definitions ...
    }
