SB5101 - NO Access / MAC Changed

[southernyankey1970]

I am experiencing the same with a 5100. It happened to me before and I thought I used Jtag Util console to change the addresses but cant remember how I did it. Maybe it was telnet. But I cannot telnet into the 5100. If you can telnet into it try it but I do not know the commands.

reflash it. your certs get smoked when you change only the mac addy. Basic bpi authentication will get you a rng resp from the cmts because you killed the certs.
