Hi,
We are about to purchase a Cisco MC20x20-5D linecard (5 Downstream licence) Someone told me that we could do D3 bonding with this but I wasn't familiar with the 5 license being able to do bonding? Any insight?
"With a 5DS license, one DS channel is enabled from each controller from the card. Even with 5 DS license only in 20x20 LC, you should be able to assign DS channels from different controllers to the same DS bonding group (wideband-cable interface) so you should normally be able to do DS bonding with such a group."
What I would like to accomplish with this setup would be the follow. We have low usage from the node groups connecting to this card. We run an entire fiber to feeder network and as so only acquire around 20-30 modems per node. What we would like to setup is 1 fiber node being supplies all 5 downstreams and have the d1/2 modems load balance across the 5 and have the wideband bond the channels. As for upstream we would have 10 nodes connected with 2 upstreams per node and have the d1/2 on one channel and the wideband bond both upstreams. Basically we would make 1 Mac domain out of line card if possible. Any enlightenment?
Thanks Mbowe! I was not aware of the Mac-Domain limit. At this rate I will most likely have a 1:4 ratio DS:US and then just create a bonding group between the Downstreams
5DS license mean 5 DS port with one freq. each one. To have the bonding capability you should buy the 20DS license 5DS port with 4 freq. on each.
This is what sales has informed me of...

Does this sound accurate?
You can assign each downstream of each controller (1 per controller because of your 5 licenses) to any MAC domain you want.
E.g:
interface Cable5/0/0
downstream Integrated-Cable 5/0/3 rf-channel 0 upstream 0-3
downstream Integrated-Cable 5/0/2 rf-channel 0 upstream 0-3
Here you are assigning to MAC Domain 5/0/0 two DS of your controllers.
You also can assign any controller of your card to a WB channel through interface wideband-cable X/X/X:X.
Thank You!

There is a limit of 8 US per mac-domain.
