Reset a CM from SNMP

Hi there,

i need help on reseting a Cable Modem from linux with snmp either directly with ip or in any way that i can do it .
I can read ip, mac , tx power , rx power and other values but i don't know how to reset a modem to do a reprovision of the modem again.

I've tried many things without success.
as i have read some details about this comand
snmpset -v1 -c public 172.33.55.11 1.3.6.1.2.1.69.1.1.3.0 i 1

it needed to work but to me it's not working.
What i need to do is reset a modem that i know his mac adres or his IP adress .

I would be thankful if anyone could post a solution to this issue.
