I have SNMP access to cablems on my lab CMTS. I am not sure if this access is restricted.
How do I make sure that any device on my lab CMTS has unrestricted access to every Cable modem. No restrictions.
Here is what I am trying do:
I need to be able to factory reset Cable Modems through SNMP.
I need to do it so that web access username/password of the modem is reset to default.
I also need to reset all the settings.
I am working with Motorola, Arris, SMC and other manufacturer cable modems.
I have my own test head-end to be able to do this. So I have all access to settings, snmp etc.
Does anybody know how I can do this through SNMP or through some other access like telnet? The manual reset by pressing button wont work for me.
I am attempting to get an Arris TM822G to connect to my Ubr10012. It is getting stuck at init(d). The Ubr is currently running in Docsis 1.1 mode. We are using CNR 6.2.3 as the DHCP Server. I have other Arris devices that work without a hitch. We are currently utilizing TM602A, TM602G,Tm604G, TM608G and I have even attached their Docsis 3.0 modem CM820A without a hitch. Th reason for this is that we will be migrating to Docsis 3.0 very soon and it would be helpful to be able to do it in steps as opposed to having to swap all of our modems at once.
Can anybody give me an example access list to allow certain ip addresses ssh access in to the BSR. Also does this acl just need to be applied to the loopback and GigE interfaces?
Somewhere, one person told me D3.0 is useful to get easier noise hunting than D2.0. I don't know if that is correct or is a myth. I know D3.0 has bandwidth advantages but is good for noise cancellation? Is easier to hunt noise with D3.0? What would be the main difference?
We currently have 42 nodes broken down into 5 upstream (return) node groups. On the downstream (forward) side of the plant, we have a single node group. We would like to break the downstream into 4 node groups. The way the math works, we will have 10 downstream channels per node group and we will have 2 downstream channels that cover all 4 node groups. We will be using an ATX Q-Series amplifier to provide channel isolation between the four node groups.
Hello ,
Not sure whats going on with the Ethernet ports in back , but I lost connection to all modems and I have already power cycled the bsr and I noticed the Ethernet port link lights come on with all ports except the first top left port. But I am only plugged into the bottom middle port , so no other data cables are plugged into the other ports but the link lights all show up anyway? I have a "fail" light on front as the only error and I have already tried new cables. Any ideas or perhaps I have a bad circuit or port panel?
