use of allow/deny to assign a specific attribute

[Lanckmans Sven]

Hi,

what if there's a filename attribute in the class *and* in the range? Which one will have priority?

class "class1" {
match if ((option agent.remote-id = substring(hardware, 1, 6));
filename "class.cm";
}
shared-network "NETWORK1" {
subnet 10.10.10.0 netmask 255.255.255.0
pool {
      range 10.10.10.2 10.10.10.254;
      allow-member class1;
      filename "pool.cm";
       }
}

Will the modem boot with class.cm or pool.cm?

Thanks,
Sven.

Make ‘ filename’ part of the class definition.

Here is an example:

class "pxeclients" {
   match if substring(option vendor-class-identifier, 0, 9) = "PXEClient";
   next-server TFTP server address;
   filename "/pxelinux.0";
}

Thus when class can be invoked, those options will be invoked.

Hi,

is it possible to assign a specific attribute (for example "filename" which has the bootfile name) per class without having to use a seperate pool for each class.

Example:

class "class1" {
match if ((option agent.remote-id = substring(hardware, 1, 6))
}
class "class2" {
match if ((not(option agent.remote-id = substring(hardware, 1, 6)))
}
shared-network "NETWORK1" {
subnet 10.10.10.0 netmask 255.255.255.0
pool {
      range 10.10.10.2 10.10.10.254
       ** here I need some allow-code to give class1 the option filename = file1.cm
               ** here I need some allow-code to give class2 the option filename = file2.cm

       }
}

Currently we can only achieve this by splitting the shared-network up into multiple pools, but this seems overkill for changing just one attribute (and doesn't scale for us)

Thanks,
Sven.
