Docsis chat

Hi there,

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:

arrisCmDoc30SetupExtendedUpstreamTransmitPowerValue.0 (Integer32) 0

I hope this information can help someone else.

Regards

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.

Hi!!!

i'm in trouble with some TLS dot1Q over a Cisco uBR 7225

my topology is the following
SWL3 --- uBR --- CM --- CPE

i'm using VLAN int 2717 in SWL3 and i need to reach the CPE.
these are the lines in the uBR

cable l2-vpn-service xconnect nsi dot1q
cable dot1q-vc-map H.H.H GigabitEthernet0/3 2717

and just enable the BPI in the DOCSIS file TLV29 and with some commands on cable interfaces

Hi,

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..

Hi!

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?

Hello,

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?

how to enable SSH on Cisco DPC3000?

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':

Hello everyone,

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?

Hello,

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.
