I have a Cisco ME switch and I am trying to figure out the Option 43 with Suboption 21 configuration. I need to point the AP to two different servers so first one requires sub option 06 (HEX) and second one requires sub option 15(HEX). I have done that but it isn't working. So far I have tried:
06....IP15...IP
Is there any other format that is needed perhaps I am missing some thing here. Thank you.
as per last time i have tested with some Meraki devices (my IP example - 202.63.96.9)
HEX for 32:30:32:2e:36:33:2e:39:36:2e:39
06:15:IPHEXHERE:2c:15:IPHEXHERE
Here is a quick example
Option 43 sub-options are sent as TLV:
<option-code><length><value><seperator> <option-code><length><value><seperator> etc.
So in your case it should be:
06 <length may be 0x20 for 32-bit IP><Your IP Address for 0x6> 00 15 <length for 32-bit IP><Your IP Address for 0x15> 00
