We have an used Arrris C3 CMTS and we are performing some test before final instalation..
We have installed the CMTS, set the required parametars like ip helper address, upstream and downstream channels, frequencies, and we test 2 cable modems.
The modems have synchronized the Downstream and Upstream and they go in int(d) state…
After a while they go to offline mode but they never receive IP address...
I have a small network at an apartment complex, very basic config files, rate limits set to 0, maxCPE set to 1 just a 1.0 config. I have a simple server set up with DHCPd to give the modems what they need to boot. I handle actual user authentication by MAC and rate limiting on my core router. I chose to do it this way as this is how the rest of the network functions. The rest of the network is either wired ethernet or ptmp wireless which we cover a large part of the city with.
Im trying to get a new mc88v working and I cant even get a modem to register at all. Not doing any bonding... no DOCSIS 3... Any idea what I might have wrong?
We're having a bit of a struggle getting high throughput on upstream traffic in a BSR 1000 EuroDOCSIS. Aggregate throughput seems to be OK and as expected by the 3.2 MHz width and 16QAM modulation (we see peaks of 7 Mbps, so there should be headroom to the maximum capacity of 8.8 Mbps with this setup). The problem is the throughput for each modem which maxes out just below 3 Mbps. I'm used to D2.0 where I believe things are handled a bit differently, and I know I have had cases where an SB5101E has used up all 8.8 Mbps of a similar channel.
Newly installed uBR7246vxr.....working great all except for some reason people using Windows Vista/7 PPPoE frequently disconnects like every minute.
If they are using a router, no problem stays log in. It is happening on different computers, on different ports. I can't even duplicate the problem. I thought it might be malware causing it, but that does not appear to be the issue. I've switched out modems, levels are good, modems aren't losing connection to the CMTS, just PPPoE sessions.
I came across this " step in MULPI ATP - Configure the CMTS to send a DBC-REQ message with a Client MAC Address encoding (type 50.4.1) to CMUT, using test MIB mode 122."
Does anyone know how to configure Test Mib 122 on Arris c4 CMTS or any clue appreciated.
we habe a Cisco 10k M-CMTS over the whole hf-filed I have Modems they are not go online. In some cases it's a really hf-issue, like a amplifier or the wired connection, but in the most cases there are no hf or other problems in the network.
how can i solve this problem? why didn't send teh teh REG-ACK Message ( or the cmts dont receive this message).
