Docsis chat

I need help to diagnose and solve a problem with packet loss on FastEthernet interface on UBR7246 (not VXR).
When I ping this interface in way that simulates VoIP traffic (every 20 ms packet size of 350 bytes) between 5 and 30 packets of 1000 are lost.
Number of lost packets correlates with traffic through CMTS. For instance, if I shutdown cable interface, and thus eliminating traffic, there is no loss. On the other hand, even small traffic, eg. 1 MBit/s, causes packet loss.
Such loss doesn't make any trouble for internet users but has severe impact on telephone users.

Hello,

Do the Arris TM402, TM502 and TM602 series EMTAs all take the same firmware? I have the latest (TS 6.1.77 DOCSIS - PacketCable SIP
Oct 30, 2009) I have only one TM602G and it refuses to take the firmware. I'm wondering if it is just bad because it's my only one.

Thanks,
Eric

Hello

We use Motorola SBV5121E with SBV5121E-SIP-1.0.4-SCM-01-SHPC firmware. But the documentation we have received along with this version of software is very incomplete.

I would like to ask - maybe somebody can provide documentation describing the configuration (MIBs, snmp options, configs), both - the modem and the voip part (CM and eMTA).
And maybe some new firmware?

Sorry for my poor english :-)

hey all,

long time no talk. I have weird problems, my cmts1 and cmts2 CPE equipment gets stupid. I have situation as follows:

subnet 10.10.0.0 - for dhcpd server,
subnet 10.11.0.0/24 - for CMTS1 cable modems,
subnet 10.12.0.0/24 - for CMTS2 cable modems,
subnet 100.100.0.0/24 - for CMTS1 users (CPE),
subnet 100.200.0.0/24 - for CMTS2 users (CPE).

actual setup is like:
subnet 100.100.0.0 netmask 255.255.254.0 {
pool {
always-broadcast on;
range 100.100.0.11 100.100.1.254;
option routers 100.100.0.10;
option broadcast-address 100.100.1.255;

Can anyone shed some light on problems with this cable modem and ISC DHCPD server ?

Anyone have firmware for this and a mfg CVC?

Hello,

I have a question that can be banned from allocating IP addresses of CPE, options MAXCPE 0; does not work, right there are other options?

Thanks.
