The issue is: Network Topology Is below

We are trying to send broadcast traffic from the CPE device hanging off the cable modems to the Head Linux PC via the CMTS-C2200. We are seeing that the broadcast traffic is being broadcast from Linux PC – B, but it is not being seen by Linux PC – A or C. Even though Linux PC – B and C are on the same network. This is also true if Linux PC – A sends a broadcast message, Linux PC – B and C will not receive it. We are seeing that the CMTS-C2200 is receiving lots of broadcast packets on the downstream, but none on the upstream.

Hello,

does someone have a MIB or some documentation about how to access cable modem remote query data collected by the CMTS over SNMP?
Thanks in advance!

Hi guys, we are running catv high-end application, right now we have DVB-C CATV and IPTV distribution, we use hdmi qam modulators, RF combiners and splitters, for IPTV we use cisco switches. We would like to try to go with DOCSIS standarts, what equipment we need to buy and from where to start? Thank you!

I am unable to remove manual IP binding from the dhcp pool so I may use them again for another modem. I am using the no version of the command.
TO ADD -
ip dhcp pool cm-ups-000b.c914.1E63
host 10.1.0.89 255.255.0.0
client-identifier 0100.0bc9.141E.63
!
exit
TO REMOVE -
NO ip dhcp pool cm-ups-000b.c914.1E63
NO host 10.1.0.89 255.255.0.0
!
exit

This is not working. Does anyone have any suggestions?

We have a scenario we are trying to solve using the IPDR-CPE-TYPE but have not found a work around yet.
Is there a way for the CPE-TYPE IPDR record to pull more than 1 IP address when the same MAC is used?
We see some customers have a Cable Modem in “bridge mode” and a CPE device behind the cable modem that has two or more IPs on a single MAC address.

Hi all! Thanks all future help :)

I am trying to configure a 16 Channel bonding group using a MC20x20 & a Arris TG1672. I can build a bonding group for 4 Channels and 8 Channels and the modem locks no problem. Any more than 8 channels and the modem defaults to 1 channel. I have check that all 16 downstream channels are at the modem. Do I need to create a RCC-Template or is there something I'm missing? I will post my config when I get back to the office. Thanks

I've been going through the manual for the BSR64K trying to figure out why things are the way that they are and I came across this. show cable service-class.

If I'm reading this correctly, I might have found why we're getting issues with our VOIP. I'm coming in behind someone else who "Self-taught" using this particular set of BSR's as their tool for learning, so I'm always finding joyful little tidbits of things that don't make much sense to me. This is one of them.
