What is DOCSIS MIMO?
Was upgraded to a new firmware version on my SB6120 via Service Electric.
A couple of new items appeared in the web diagnostics since this update. An Open Source tab crediting open source GPL licensing, and a new DOCSIS MIMO Honor MDD IP Mode.
Anyone know what DOCSIS MIMO is?
Also a few new warning logs:
5-Warning Z00.0 MIMO Event MIMO: Stored MIMO=-1 post cfg file MIMO=-1;CM-MAC=00:23:74:xx:xx:xx;CMTS-MAC=00:01:5c:xx:xx:xx;CM-QOS=1.1;CM-VER=3.0;
I understand MIMO in 802.11n as in multiple antennas.
This is firmware: SB_KOMODO-22.214.171.124-SCM00-NOSH
They couldn't be bothered to come up with a unique acronym.
DOCSIS MIMO stands for MDD IP Mode Overide.
On a D3 cable modem system, the CMTS sends a packet called an MDD or Mac Domain Descriptor that tells the modem specific details about the cable plant. Some of those things are TLV 5.1 and 5.2. They determine whether the cable modem attempts to boot up in IPv6 or IPv4 mode.
If there's a difference between the current operation mode and what is specified in the MDD (this error often comes from a difference in the modem config file, and what is being transmitted in the MDD). It shouldn't affect operation of the modem, as it's just a notification.
Thanks for the info!
They have been busy in the last few months. There's 8 downstream channels and new firmware. They say soon new speeds too, maybe around Christmas time.
Gotta love innovation.
