=============================================================

Basically i want restart the CM with the MTA MAC or CPE MAC, I was tolking with Fernando Ramos an he told me that since the version SCG this is not possible it was restricted by security reason.

Conditions:
Customer try to delete a cable modem using the following => Clear Cable modem <MAC CPE> reset or delete

this command works fine in older version than SCH
