mc3gx60v conf question

Hi,

for the need of the example I use the controller card 6/1/0 72D/60U
I use control plane conf config with my edgeqam
My setup is: MC3gx60v ---> switch---10Gb> edgeqam

sample config ( working)

retransmit timeout max 5

I know that each Ge card ( GigabitEthernet6/1/0 - GigabitEthernet6/1/2 - GigabitEthernet6/1/4)
are map to a controller ( 6/1/0 - 6/1/1 - 6/1/2)

My question is: Do I need to configure a IP on each GE to communicate with my edgeqam

Lets a ubr full of mc3gx60 (8) and 3 GE interface each = 24 port GE, do I need to configure a IP on each GE ?
Can I use the same IP for all my controllers to communicate with my edgeqam ( 1.1.5.2 in this example)

Thanks

Pascal

There is an L2TP tunnel from

There is an L2TP tunnel from each CMTS gig port to the edgeqam

Thus each CMTS gig port needs to have valid IP routing (eg a /30 allocated per port)

If you are sending all the traffic to a single 10gig port on edgeqam, then I would imagine that each CMTS gig port will need its own VLAN, or you will need to load multiple /30 secondary subnets onto the edgeqam 10gig port

Also I would suggest putting all these CMTS gig ports into a dedicated VRF, to keep them isolated from the rest of the cable network routing table

Hi mbowe,

Hi mbowe,

See attachment, do you think I'm ok with this setup and do you know what other cable plan do ?

All my l2tp tunnel will have the same edgqam ip to establish the link

Thanks for you help.

I never used a switch between

I never used a switch between CMTS and RFGW10, single point of failure. :-)
And I only used QAM-Ports x/1 - x/4 and x/9 - x/12 because of the 1Gig/s limitation each 48QAM linecard had. So we only used a bonding of 16DS.
Between controller and linecard we used to configure /30 networks.

The controller configuration in my case look like this:
controller Modular-Cable 5/0/0
ip-address 172.16.250.1
rf-channel 0 description rfgw10 QAM3/1.1
rf-channel 0 cable downstream channel-id 1

rf-channel 2 ip-address 172.16.250.2 mac-address 0022.9084.2dbf depi-remote-id 1050002
no rf-channel 2 rf-shutdown

on the other side the rfgw10 configuration:

Hi fschlums

Hi fschlums

I use apex3k as edgeqam so I need to use a switch between, I"m not familiar witch RFGW10
how many DS are you using by mc3gx60v card ? ( 3 controller x 24DS(6qam)
each controlleur can share 1Gig/s for 24DS ( 3-8x4 nodes)

In my case i'm trying to do the maximum 8x4 bonding by card. each card has 72DS ( 3controller/24DS) so I was thinking doing 9 nodes 8x4
