Docsis chat

Hi,

Please could someone help me to configure NAT for the MTA RANGE to reach ONLY DNS (PUBLIC IP X.X.X.Y) THIS DNS is behind a router that i don't have the control.

Here is an extract of the config
!
ip cef
ip dhcp relay information option
!
ip dhcp-server X.X.X.3 // PUBLIC IP
!

interface GigabitEthernet0/1
ip address X.X.X.X 255.255.255.240 //PUBLIC IP
duplex auto
speed auto
media-type rj45
negotiation auto
!
!
interface Bundle1
ip address Y.Y.232.1 255.255.252.0 secondary // PUBLIC IP FOR CPE

I have a CMTS BSR1000 and the firmware version currently have is 2.0.1.10.PRRU.

Does anyone know which is the latest version?

Thank you

Dumb question but how may CPE's can a docsis 1.0 CM file allow? Is there even a limit? I am trying to come off of a cable modem (Building A) that has a static public ip and wirelessly send ethernet across a lake using two mikrotik 411 routerboards then go into a CMTS again (Building B). I do not desire to NAT behind the second CMTS so i am wanting to allow public IP's (CPE side) on my class c to tunnel through.

Hey, smee again.

Need more help :( I am stuck at different end: my MTA's get an IP address. However, after DHCP ack package, I never get to see TFTP request from MTA at my provisioning server. What strikes me as very odd is some sort of the routing problem that I cannot get hold of. I have 3 networks - 2 fixed subnets / IP addresses for both CMs and MTAs, and 1 pool set up for CPE. I use ISC-dhcpd, fourth network is defined just for the sake of the dhcpd.

Hi,
I'm using a Terayon BW3200 with Motorola 5101 modems. The maximum download speed I get is 12 Mbps. Would like to know if this is the maximum speed I can achieve with these hardware. BTW, I've a DS3 Internet connection, getting same result with local servers.

Thanks,
Christian

After reset to factory default i cant change to eurodocsis :/

remote1> cable europe
failed

Any help?
thanks :)

Ok problem solved :) i have admin-status down in cable-level :P

Hello,

I'm working on a system that uses a C3 and wireless DOCSIS. I just need to increase the SNR. currently the down SNRs are from 22 db to 32 db. I'm very familiar with DOCSIS. Does wireless use the same standards? Down power -18 to +18, Down SNR should be about 30db, Up power should be about 45db but can't go over 61db, Up SNR (read at the CMTS) should be about 30db??? Should I start tweaking the cm config file or the modulation profiles. The C3 is licensed for SCDMA, should I use that or TDMA or ATDMA? I have a plan, but would just like some opinions.

Hi, all

I run fedora with docsis_server, whenever I check processes on the server, there is a TON of dead (defunct) processes for docsis_server. While I know I can resolve this with cronned script, I wonder do any of you have idea why is this happening?

Can somebody confirm this. I have situation where docsis_server 3.5 sends wrong IP address in ACK packet for cable modems. It is IP+1 or IP+2 from value in OFFER packet.

Some of the cable modems doesn't mind this, but some of the do, and they end up stuck in init(i)...

select * from dhcp_log;
+------------+----------+----------+---------+------+--------------+-------------+--------------+-----------+-----------------+--------+
| thedate | thetime | serverid | sending | type | dynamic_flag | mcache_flag | b_macaddr | b_ipaddr | b_modem_macaddr | subnum |

Hi,

I'm new to docsis software.
I installed: DOCSIS Configuration File creator, version 0.9.5
on FreeBSD 7.1.
During creation :docsis -e tol.txt key_file tol.cm
I received :

Final content of config file:
------------------------ cut
Main
{
NetworkAccess 1;
SnmpMibObject
SnmpMibObject experimental83.1.2.1.4.1 String "public" ;
SnmpMibObject
SnmpMibObject experimental83.1.2.1.6.1 String "@" ;
SnmpMibObject
SnmpMibObject
SnmpMibObject
SnmpMibObject
SnmpMibObject
SnmpMibObject
------------------------ cut
which is wrong.
