I got quite a few TCM471's with problematic behaviour - it stucks in init(io), probably due to plant quality problems (to be fixed ina future :mrgreen: ). I'd like to force those modems to not bond 8x4 but 8x1 but not by "no cable mtc-mode" because it affects ALL of the modems in a plant. Is there any specific OID for this CM or maybe some other way?
I use Motorola/CBN SVG6540E cable modems and they have a problem with wireless. The modem works fine a couple of days and then the wireless led light goes off and there is no wireless service anymore. I have tried to reset but no result. Do you have any idea what happens?
I tried to set saCmMtaCliAccessType to enableSshPermanent (3)
saCmMtaCliAccessType - 1.3.6.1.4.1.1429.78.1.1001.1
[Controls telnet/SSH access to the CM IP Address. When username and password are specified, the value of this object can be modified to control telnet/SSH access. In this case, the object returns the current value when read (disable(0) by default).]
But I can no set username and password since they have 'Access: not-accessible':
I am trying to set up a small lab network to test IPV6 on DOCSIS network. I am having difficulty in getting a cable modem to receive DHCPv6 IP address.
I am using the following equipment:
- Cisco uBR7200 with NPE-G2 and MC28U
- ISC-DHCP-SERVER6 running on Ubuntu 14.04
- DOCSIS 3 IPv6 compatible cable modem
Wireshark shows me that IPV6 Solicit packets are received from the modem and the DHCPv6 server sends Advertisement back.
We have a Cisco 7246VXR with an MC-28U card. So far, we have only been using a single downstream with multiple upstreams (based on the fiber-node it's coming from). We are now looking to implement load-balancing, primarily on the downstream side. I think I have the configuration side down, but the physical layout is something I need assistance with. Do we just drop a 2 way splitter and put US0 of each DS on the same splitter, or can we leave out current setup alone with just adding the second downstream to the mix?
I need to know if there is any possibility to restrict users from connecting their router after the cable modem and then distribute the service?
They have to connect only PC not routers.
Ive got a docsis_server 3.5 setup running on Debian, and I'm having issues with modems not getting any ip addresses. Sys_log is hinting at a subnet or giaddress issue, but i have it set, as far as I can tell, to what it is expecting.
sys_log:
"2014-08-10","04:27:34","1","4","NEW CM GIaddr mismatch (the CM moved) gi 10.19.16.1 ip vlan 1"
"2014-08-10","04:27:34","1","4","NAK -- no subnet for ip mac 0019a68ba09a vlan 1"
Hello,
Is it possible to create a config file with lets say maxcpe 4 modems, and set it to be the first given IP a public IP, and the next 3 IP's a private IP's?
I haven't found much information on this so far, I was wondering if it was possible to setup a static Internet IP address to a CPE directly into a specific CM configfile?
1. As we know, CMTS uses Downstream to send packets to CM. How does the single instance of packet sends to multiple CM. At which place these packets get duplicated.
2. Also how does the specific packets (channel) are served to some CM. (eg paid channel, on demand TV), Since Downstream will send the packets to all CM.
