8x4 Channel Bonding

We are doing testing for 8x4 Channel Bonding, and are seeing an unusual phenomenon. With 1GHz splitters (2-, 3-, 4-way) and with 1.2GHz (2-, 3-, 4-way) our test modems will not lock onto all 8 channels down; however, when we use our IPTV/MoCA1.1 1.5GHz splitters (2-, 3-, 4-way) they will lock onto all 8 downstreams. Interestingly, if we use 2 1GHz splitters, it will lock on. And we have tried frequencies in the low 700s and in the upper 400s. Signals look good on every (locked and not locked) tests; however, when it locks onto all 8, we have noticed the downstreams seem to hit around -5 --- -8dBmV. Has anyone seen/heard any similar issues?

Sounds pretty strange

Sounds pretty strange

Are your 8 DS frequencies all contiguous?

What brand/model CMTS and modems?

darekc
Have you checked

Have you checked microreflection ? is that above 26 dBc ?

Lots of things

There are so many things that could be causing this, but go back to your basics. If you're doing this in a lab set up, make sure all your connectors and cable are good and snug. Is that the level you should be hitting the modem at given your test setup? Follow the signal. Find where its good/bad. Don't overthink it, RF-wise, there is nothing special about 8 downstream channels.

It is very strange. First

It is very strange. First off, our test environment includes 2 sets of 8 contiguous frequencies, one starting at 447MHz, and the other starting at 693MHz. Also our CMTS is a Cisco uBR 10k and the test modem is a Motorola SBG6580 (with the latest stable firmware). As far as microreflections and other RF impairments, we will have to borrow one of the field meters for all the in-depth information there. And the basics, all double checked, snug, and changed out again to eliminate the possibility of failed components. This isn't quiet as big of an issue as before, because it has better results with a few other coax drops in other parts of our building, so the issue might be as simple as mine is bad, lol! More broadly- does anyone have some advice for our 8x4 bonded testing? Or maybe hiccups to watch out for? Thanks

Capm
Yea

Yea, make sure you have two sets of 4-channel wideband channels configured per 8-channel wideband - and I learned this the hard way, and finally mbowe (all hail master of the cisco10k! ;) mentioned something in on another problem that clued me into the solution - if you don't, 4-channel modems won't bond at all. Likewise, if you have any 3-channel modems in your plant, they won't bond unless there is a 3-channel wideband configured.

So you're running 16 downstreams at the same time to the same plant? How do you have your load balancing configured - or are you forcing modems to one or the other in the configs? That could make your modems take longer to lock on as well, I would think.

Is your return clean/wide enough for 4 channel? You'll also have to re-optomize your return links in your nodes for the additional rf loads. Hope you don't have FP's!

For sure want to get a meter and make sure everythings good between you and the cmts.

4-channel not bonding

The earlier issue has been resolved, but now we have a different issue (which I believe you mentioned at the start of your post). We have 8 channels and 8-CH modems lock on great; however, 4-CH do not (they come in at 1x1).

Config snippet:

Also, is anyone out there running 16-CH down?

Don't make the 2nd wideband a

Don't make the 2nd wideband a "cable bonding-group-secondary".

Secondary bonding groups are a special piece of config which would be used to direct multicast/IPTV to a set of DS which have been "spanned" across multiple MAC domains. You don't need that if you are just doing typical internet traffic.

Are you running MC20X20v linecards? If so a typical config would be to each card for 4 mac domains (4 DS per mac domain), and then span the 5th set of 4 DS across the first 4 mac-domains. Config like this :

repeat for

wide-5/0/2:0
wide-5/0/2:1

wide-5/0/3:0
wide-5/0/3:1

You dont enter any config for 5/0/4, as these 4 DS are being used as non-primary DS in the 8 way bonding groups above. The only config for 5/0/4 would be something like this :

interface Cable5/0/4
description ** no primary downstreams here, no upstreams either
no cable packet-cache
cable upstream max-ports 1
no cable upstream 0 connector

You would wire your forward combiner so that the 5/0/4 DS are sent to 5/0/0, 5/0/1, 5/0/2 and 5/0/4 mac domains.

Hope that helps!

Right, that is how we had the

Right, that is how we had the config in the first place... What we ran into was-- if we had 8 channels in 5/1/0:0, the 8-CH modems would work and the 4-CH would lock 1DS (without the bonding-group-sec); however, if we made the 5/1/0:0 have 4 channels, the 8-CH & 4-CH would lock 4 channels each. It's almost as if the 4-CH modems are seeing the first wideband group :0, saying "I can't do 8..." and locking onto a legacy Integrated-Cable 1 channel.

How we have been testing:

**we were testing load balancing across a card, by sending 20 freqs to one area, unfortunately link budget will only allow about 8 nodes to be serviced in this one-card setup, instead of the 25-30 we have currently.

Did you get your 8x4 Working?

I am in the same boat, and am hoping you could share your success if you have this working now? Since I am not sure what part of my config is going sideways, I am looking for someone who has nailed the 8x4 scenario to share the ...

Physical Interface Config
Wideband Interface Confg
Fiber Node Config

Presently, when I try to apply the configuration suggested by MBOWE, I am receiving the following error:
uBR4-10K(config-if)#cable rf-channel controller 4 channel 0 bandwidth-percent 1 remaining ratio 100
% Cannot allocate 1% bandwidth to rf-channel 0 on controller 8/0/4

We are running an integrated CMTS with MC20X20V

Thanks in advance!

16-CH down

I am finding this a bit strange. There was a heap of noise from the modem manufacturers saying how they would have gear available at the end of last year. But from then on the availability dates have kept blowing out. I still haven't had a chance to try one in person (even early engineering units).
