Hi all,
I'm start with CMTS
I have one CMTS 7246vrx With 2 linecard MC 28, In now I want config 1 Downstream suppor for 8 Upstream. Is there any way to do it ?
assume you will config a MC28U in slot 3. I don't know if your cable interfaces are already configured with old commands, so I'll reset both cable interfaces on slot 3 first.
Dear Wittmann
My purpose is want two Ds Port support for 8 Us, that mean the subscribers( of 8 Node) can option 2 Channel DS for transmission and reduce traffic congestion, Do your config resolves this problem ?
Hi, this configuration what you want is not possible with your DOCSIS 2.0 CMTS. First on DOCSIS 3.0 you can add more as one downstream channel to the MAC Domain. In your case I think the solution is to use for each upstream connector a two-way splitter and feed each fiber-node with two upstreams. One from each MAC Domain.

configure terminal
! make default config on interface cable 3/0 and 3/1
default interface cable 3/0
default interface cable 3/1
!
interface cable 3/1
! Remove 4 upstreams from interface cable 3/1
cable upstream max-port 0
interface cable 3/0
! Extend initial 4 upstreams to 8 upstreams on interface cable 3/1
cable upstream max-port 8
! mapping upstream channels to upstream ports
cable upstream 0 connector 0
cable upstream 1 connector 1
cable upstream 2 connector 2
cable upstream 3 connector 3
cable upstream 4 connector 4
cable upstream 5 connector 5
cable upstream 6 connector 6
cable upstream 7 connector 7
Now you can configure up to 8 upstreams on the interface cable 3/0
Best regards,
