Cisco AP's with Option 43

[Frank Bulk]

If this is TLV, then the '04' is the length of the text -- 4 characters,
namely 10.1.3.2.

Thanks Randy and Alan, that did it.

For the F1:04:0A:01:03:02 string I was able to find how the code 241 is
F1 in hex and the server adds the 04 and converts ip to hex so I
understand that.  I still have one more question though.  Are the vendor
encapsulated options always 43?

Also I submitted a request on the cisco site for them to update the
webpage for isc dhcp.  I imagine someone else has asked them to do this
before, but it's worth a try.

Thanks again,
Austin

We do not make subnet distinctions as you are attempting, my config
(sans actual address) is below. You might try placing the subclass in
subnet definitions leaving the class outside.

option space LWAPP;
option LWAPP.controller code 241 = ip-address;
class "LWAPP" {
  match option vendor-class-identifier;
}

subclass "LWAPP" "Cisco AP c1130"
{
  vendor-option-space LWAPP;
  option LWAPP.controller 10.20.30.40;
}
subclass "LWAPP" "Cisco AP c1200"
{
  vendor-option-space LWAPP;
  option LWAPP.controller 10.20.30.40;
}
subclass "LWAPP" "Cisco AP c1240"
{
  vendor-option-space LWAPP;
  option LWAPP.controller 10.20.30.40;
}
subclass "LWAPP" "Cisco AP c1241"
{
  vendor-option-space LWAPP;
  option LWAPP.controller 10.20.30.40;
}
subclass "LWAPP" "Cisco AP c1140"
{
  vendor-option-space LWAPP;
  option LWAPP.controller 10.20.30.40;
}
subclass "LWAPP" "ArubaAP"
{
  vendor-option-space LWAPP;
  option LWAPP.controller 10.20.30.40;
}
