Im working with a very interesting issue. Worldwide there is a BIG issue with Intel Puma based cable modems. These are in use all over the world. These ALL have a CVSSv3 7.3 rated DoS attack that cannot be blocked at the ISP of a MSO because the hardware would cost $1M USD per ISP hub installation. The main issue is that these MAJOR ISPs are going 40Gbps and 100Gbps connections going to single CMTS boxes. Dealing with 10's of millions of clients.
Even though I have configured with all possible setting,the scenario is still the same.i.e Single Logical channel 6/0/2:2 is not functioning.Can anyone help me through out this??
Hi
So i configurated my miniCMTS with DHCP,TFTP i enabled downstream and upstreams channels and everything is working fine i think.Problem is when i connect modem to the CMTS, modem will complete every step(downstream search ,ranging ,dhcp,tftp atd.) and after that every LED just go yellow and modem resets .So yea i dont understand where problem could be.
