Our DSL network uses TR069 to manage our DSL modems. When a DSL modem with a factory reset configuration comes online, it logs it with the username “autoconfig” and then attempts to download its configuration from the TR069 management server. Since we are dealing with Customer Service reps entering MAC addresses into the server, there are often times mistyped MAC addresses so the modem is stuck in “autoconfig”.
I currently have 23 Mikrotik routers being used as PPPoE aggregators and would like to script a SNMP probe to find all the modems logged in with “autoconfig” and e-mail a report. I have everything written except that I cannot find a way to extract the MAC address behind the PPP connection. It is reported as “Caller ID” in winbox:

But I did a full walk of the SNMP tree on several of our units and these MAC addresses are not showing up anywhere in the SNMP tree. Is there a hidden MIB somewhere I am missing? Or is the MAC address of PPP connections just not reported in SNMP?
