Good call. It is stored the same way, thanks! -Travis

I’m using memfile (CSV) for leases so not sure if format differs from
SQL, but CSV format for user_context field is JSON with attribute name
of “relay-agent-info” and the value is entire option 82 hex value as
sent over wire. Assuming SQL value is same, you could parse hex
value into sub options 1 and 2 per RFC 3046:

Is there a delimiter or a way to pull the sub-option 2 from option 82
when it is stored in the user context through the store-extended-info
flag? I am using sql for storing leases. So far I do not see a
delimiter, I just see the two sub-options merged together and then stored.
Does anyone have any ideas on a good way to store just the sub-option 2
so it can be recalled? The end goal that I need is IP, hwaddr, and
option82 suboption2. I cant definitively say that suboption 2 will be a
mac address, or X amount of characters, otherwise it wouldnt be too
difficult. I was thinking about using a script and writing into another
table, but that feels sloppy to me and a good way for something to get
missed or out of sync.
Thanks, Travis
