DOCSIS 3 Modems with Windows DHCP Server

Forums: 

I've run into this odd problem twice now, wondering if anyone else has seen a similar problem.

In both instances the following is common;
Problem only occurs with DOCSIS 3 modems regardless of manufacturer, but not DOCSIS 2 or older.
CASA CMTS using cable-helper (A 2200 and 3200)
Windows DHCP Server (Windows 2000, and 2003)

I have identical configurations with Linux DHCP servers that do not experience this problem.

Mixed config. US on UBR10k and DS on RFGW-1 EQAM

Forums: 

I've a doubt about the possibility to configure a UBR10k (PRE2 + 4x MC5x20) and RFGW-1 EQAM. I would like to configure two nodes with 8DS each (16DS in total) exclusively from the RFGW, so we will use the US from the MC5x20 LC and 16 DS from RFGW, no DS will be used on LC. Is this possible ? How could I adapt actual config. (attached) to achieve such configuration ?

Thnks,C.

Locate CMs from specific pool of IP address

Forums: 

Hello,
being new in HFC network and DOCSIS world, I was wondering if there is a way to assign to CMs IPs form different pool of addresses based on different locations in a HFC network.
More specific: we have a CMTS with an external DHCP attached to a HFC distribution network. For troubleshooting purpose I would like creating pool of address for each specific location (subnetting) and have CMs assigned an IP address based on the location where they are. That would make my life easier to detect the location of a faulty CM in the network.

Thank you for your help.
