Hi evereyone,

If i want to assign IPv6 to CPE and use CM MAC as a identifier to assign different subnet.

I have try ISC dhcp 4.2, but I can not find a way to accomplish it.

Is there any open source dhcp server support thie feature?

Please give me some suggestion,thanks

Hi.

I'm using US Drop Classifier to discard some unwanted traffic but I cannot make it to work. Is it necessary some commands on the CMTS side to support the Drop Classifiers?

The message I see being passed between CMTS and CM annouces Upstream Drop Classifier Support : 0, so I think this might be the reason the drop classifiers aren't showing up on the CM.

Thanks

Hi All,

I am running docsis 1.1 with cisco ubr7200VXR IOS 12.2(33)SCE5, with modem motorola SB5101i. I am using static service flow with two service (voice and data). I made clasifier based on udp port of voice. the plant testing is: phone and pc (both of them will get IP DCHP) connected to router (nat), router conected to modem. the result is modem and pc already get IP DCHP from router, but when I do call and browsing, both of them traffic comes in to primary DS dan US.

my configuration in CMTS:

Anyone have a copy of the 1.0.6.6 firmware /release notes?

If you could send to (remove spaces): s p eaker 219 -at- gmail -dot- com I'd appreciate it.

Dear All,

I'm a Cable Modem engineer.
I just got the arris(nortel)'s old CMTS, CMTS 1000 and CMTS 1100.

For debugging, I must enable this CMTS.
But I cant assign IP to cable modem.

CM succeed to lock the downstream and upstream ranging.
But there is no DHCP request from CM side. ( of cause, CM send a DHCP offer).

I have checked the CMTS's manual, so I found that this CMTS is bridge , no included the router.
So, I would like to specific the DHCP IP at this CMTS, but I can't find it.

Here is my CMTS configuration :
