We just pulled out all our old line cards and installed two MC88V cards. Everything was working fine, and still is. We have a single plant, no segmentation, AKA one spectrum group. Every port on this machine is physically combined and connected to the plant.
I'm totally new to the MC88V cards, but came up with the below configuration. This got us back to the functional level we were at before the upgrade. The problem is that I'm really unsure of the configuration.
* Is this optimal given the description of the physical plant?
* Can I lose some of these combiners? The upstreams alone run through an 8-way to a 2-way so there's room for everything....
* None of our modems will register as wide band. Why?
* Any suggestions for performance?
* Why doesn't the CMTS spread out the modems evenly?

None of our modems will register as wide band. Why?
You can't do Docsis 3.0 Service groups across blades i.e. see the docs here: http://www.cisco.com/c/en/us/td/docs/interfaces_modules/cable/broadband_... look at the restrictions for configuring MC88v cards
The other problem is you have cable mtc-mode set and no channels added to the set, mtc stands for multi transmit channels. I would either configure it or no it out.
What is your end goal as far as DSes and USes per Service Group (fiber node in Cisco terms) This is what bandwidth you are planning to provide to a single service area, i.e. node(s) or trunks out of the headend. With 2 MC88v Cards you can provide:
2 x (8ds x 2us) or
4 x (4ds x 1us)
you will not be able to do:
1 x (16ds x 4us)
this won't work for Docsis 3.0 modems

downstream Integrated-Cable 3/1 rf-channel 0-3
downstream Integrated-Cable 4/0 rf-channel 0-3
downstream Integrated-Cable 4/1 rf-channel 0-3
upstream Cable 3 connector 0-7
upstream Cable 4 connector 0-7
you could do this for 2 x (8ds x 4us):
cable fiber-node 1
downstream Integrated-Cable 3/0 rf-channel 0-3
downstream Integrated-Cable 3/1 rf-channel 0-3
upstream Cable 3 connector 0 4
cable fiber-node 2
downstream Integrated-Cable 4/0 rf-channel 0-3
downstream Integrated-Cable 4/1 rf-channel 0-3
upstream Cable 4 connector 0 4
or this for 4 x (4ds x 1us)
cable fiber-node 1
downstream Integrated-Cable 3/0 rf-channel 0-3
upstream Cable 3 connector 0
cable fiber-node 2
downstream Integrated-Cable 4/0 rf-channel 0-3
upstream Cable 4 connector 0

downstream Integrated-Cable 3/1 rf-channel 0-3
upstream Cable 3 connector 4

downstream Integrated-Cable 4/1 rf-channel 0-3
upstream Cable 4 connector 4
With the particular hardware you have, you will need to segment your plant to have smaller "nodes" to make the best use of the available bandwidth
Why doesn't the CMTS spread out the modems evenly?
There are a lot of gotchas when load balancing check out the docs here http://www.cisco.com/c/en/us/td/docs/cable/cmts/config_guide/b_cmts_ds_u...
but with the method of utilization it spreads the modems out according to Load, (and this only happens when the load threshold is reached) So until 70 percent of the bandwidth is being used, on a particular interface it will not move the modems to other ports.
you have also only configured Narrowband load balancing, i.e. d1.x and d2.0 modems you will need to check the configuration of the Wideband load balancing group to make sure it meets your needs. these are automatically configured when you create a Service group and you can see the default configuration by running the command
show running config all
We're currently looking to deploy 4 x (4ds x 1us).
We're trying really hard not to segment the plant. It's an underground, pure copper plant dug into rock basically. We can change the line gear quite easily, but adding new cable to segment the plant is cost prohibitive. We are currently reconfiguring for 1Gig service (It's currently 750) with a 5-85MHz upstream block so we will have more upstream spectrum available soon.
Once that is done, we want to get two more MC88v cards and reconfigure for 4 x (8ds x 2us).
The current fiber node configuration is there (I thought) to keep the CMTS from assigning overlapping upstream channels. Is there no way to avoid segmenting the plant?
So I changed some more stuff around with the advice above. I used spectrum grouping to stop the separate fiber nodes from walking all over each other. I also reconfigured the upstreams to only use a single physical port per line card (I think). I also narrowed the upstream channels to simplify things for now. Performance is acceptable in this configuration, at least as good as before the upgrade to MC88v cards.
Still no wideband registrations though... Here's the current configuration. Thoughts?

here is another possibility providing you have the RF spectrum to do it,
run all 2 x (8ds x 1us) on the same rf trunk and use cable modem steering to move modems around. This involves setting an attribute mask on each interface and then in the modem config file you add the required attribute mask. This way you assign each modem to each group of 8 DS.
so in this case if you had a fully loaded cmts with MC88v cards you could broadcast all 32 DS to all your homes each D3.0 modem could lock onto 8 of those DS and you could control which one.
There are some caveats though so be sure to read the docs http://www.cisco.com/c/en/us/td/docs/cable/cmts/config_guide/b_cmts_ds_u... thoroughly.
The fiber node is there to tell D3.0 modems which downstreams and upstreams are combined together. As well as to ensure upstream frequency uniqueness.
Strongly recommend against investing in MC-88V cards.
They only give you very limited network design options.
You can buy a whole uBR10k chassis with MC-20x20V cards super cheap from ebay / brokers.
MC20x20V would allow you to build a 20x8 service group which would suit your application a much better.
You are never going to get a good solution running on your network using MC-88V.
Shameless promotion: full disclosure -- I work for Casa.
If changing hardware is an option go with a Casa c40G it has a much longer lifespan (cisco 10k is nearing EOL status) will support much more bandwidth, 24 Service groups of 32+ DS per chassis (with integrated hardware) 128 service groups with Remote-PHY, versus 20 Service groups of 16DS with the 20x20 card. It also supports CCAP (putting your video through the CMTS) which could reduce your rack space significantly. The 8x96 cards can be bought as "b" stock, i.e. already used and they support docsis 3.1 DS in the next release. A C40G capable of 8 Service groups with 1 service group active will not cost much more that a 10k with 20x20 card, and it has 110-120v powering options versus 220 for the cisco 10k, and it is 6RU versus 13RU. Check out the spec sheet here http://www.casa-systems.com/product-cable.html'
While the Casa c40G is not used Cisco cheap, it is certainly within the same ballpark, but it is current technology, and a good investment for future growth.
If managing the network is not an easy task for you, Casa also has a CMTS as a service option, where you pay per subscriber, and Casa does the provisioning, hardware, NOC and much more for you.
I appreciate that, but the hardware decision/investment has already been made. I suggested the 10k many times, but didn't happen.
I was able to divy up the upstream to the fiber nodes with spectrum groups. Seems to be working well. We're getting 300+Mbps down and 20+mbps up on our test devices so things are looking good at the moment.
I have tried several times to post updates, including configuration changes, but the posts just seem to vanish. Hopefully this one gets through...
Tinnov,
I am in the process of also installing a MC88V card on a ubr7246vxr and have a few questions. I was wondering if you could email eochoa@beamspeed.com so that I may try pick your brain a bit on the installation and IOS upgrade required.
Thanks.
So I settled on the following configuration after extensive experimentation. Load balancing is working now and some modems are even connecting wideband. Ended up using spectrum groups to keep the two fiber-nodes from stepping all over each other.
Turned out the internal config-file entries aren't sufficient to do Wideband. Had to build up proper files using Excentis.
Best speed test on a wide-open modem was 175Mbps down and 2.2Mbps up. We have detected some problems in the physical plant that are potentially limiting downstream and preventing us from using the two shutdown upstreams. Also, if I change any of the upstreams to 6.4MHz, everything goes right to shit. We are fixing the physical problems in the morning and hopefully that allows our upstreams to function better.
I'm looking for suggestions on getting the maximum performance out of this setup. Am I missing anything? Is it just down to the physical plant now?
Thanks in advance!
