Netgear AX12 and CM1100 Port Aggregation

Hello,   I just received my new AX12 and so far find it an excellent upgrade.  I also have the CM11100 modem and see that both have Ethernet Port Aggregation.  I have 1 gig service with comcast. ...

    I'll dumb it down a bit more for you.

     

    Running a speed test, on a single device, directly connected to your RAX120 can only yield a max speed throughput of ~960Mbps (1Gbps minus overhead).

     

    Running another speed test, on another device, at the same time, directly connected to your RAX120, can yet again, only yield a max speed throughput of ~960Mbps (again 1Gbps minus overhead).

     

    Add the two results together and you should at least achieve 1000Mbps (full 1Gbps Internet connection). If your Internet has been over provisioned, you could see aggregated (pun intended) speeds in excess of 1Gbps. I would expect you'd achieve 1100-1200Mbps.

     

    No matter the results above, if LACP LAG has been optimally implemented in both the RAX120 and CM1100, I'd continue to use LAG between them. You never know if your ISP overprovisions in the future, LAG provides load balancing, failover, etc, etc, etc.

     

    Hopes this helps.
