ISC DHCPD MAC地址匹配类别混乱

Question

我无法成功将不同 mac 地址类别的混合与其相应的子网声明匹配。这些类别旨在区分 IP 电话、kvm 客户端和桌面。到目前为止，只有 IP 电话（grandstream 类别）正确。pcs 类别是不同种类 mac 地址的混合，但它们都属于同一类别（错误类别）。我想知道是否有人可以检查我的配置，并纠正我做错了什么？

    class "grandstream" {
    match if (substring(hardware, 1, 3) = 00:0b:82);
    }
    class "vms" {
    match if (substring(hardware, 1, 3) = 52:54:00);
    }

    class "pcs" {
    #match if not 
    #(substring(hardware, 1, 3) = 00:0b:82);
    match if (binary-to-ascii (16,8,":",substring(hardware, 1, 3)) = "24:BE:05")
    or   (binary-to-ascii (16,8,":",substring(hardware, 1, 3)) = "00:1C:C0")
    or   (binary-to-ascii (16,8,":",substring(hardware, 1, 3)) = "A4:BA:DB")
    or  (binary-to-ascii (16,8,":",substring(hardware, 1, 3)) = "02:80:FD")
    or   (binary-to-ascii (16,8,":",substring(hardware, 1, 3)) = "5C:F8:A1");
    log (debug, (binary-to-ascii (16,8,":",substring(hardware, 1, 3))));
    }
