We have struggled with a problem by using TM822 and CM820 with the updated version of FW 7.5.125 in 100% D2.0 environments. Specifically, the CM froze in init(o). After talking with technical guys at ARRIS we finally got a solution. It is necessary to set this OID to 0:
Would it be correct, for better understanding and simplicity, to classify (split) all OID Identifiers into two main categories:
1. OIDs providing status (info) about something (provisioning, load, frequency,etc) Those OIDs are read-only access.
and
2. OIDs that allow to set or change specific parameters. Those OIDs are read-write access.
Is there any benefits using Cisco MC-16S (Spectrum) instead of MC16C?
I personally have tried both Cisco Cards on my UBR7246VXR but I still don't find any difference.
I don't get the idea of the "spectrum group" could I have more upstream bandwidth using MAC-16S Cards and the
spectrum group?
I really would like to understand the differences here..
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?
