Hello,

I need Help to configure an ubrvxr7246 (12.3 21a BC3).

IP routeur headend (X.X.X.1) Public address : I have no access on it.

IP UBR X.X.X.2 Public address (interface gigabit0/1)
IP BUNDLE 1 for interface cable3/0
X.X.Y.1 public address scope for host internet
10.10.0.1 private address secondary scope for mta
172.10.0.1 private address secondary scope for cm

I would like to ping (extended) X.X.X.1 routeur headend from 10.10.0.1 and i can't.

Hi, I`m from argentina and want to set up my hfc network as described bellow, can you tell me if that it`s possible?

* Speed for internet access goes from 128 kbps to 512 kbps
* now the dream: it's possible to set up another speed for the local
network? ie: no speed limit or 1 mbps for internal ftp, gaming, or
any other transfers

1. If is possible, how to do it?
2. Where must set the second speed? (i was testing a ftp, but the
speed for transfers never pass the speed of the binary)
3. It is certain that there will need to add packet processing

I am having trouble (and have no idea except parsing DHCP server's log - but this seems to be too slow and buggy) with getting the CM's assigned IP address. I have DHCP server running on the same machine where the provisioning sw runs, IP addresses are assigned dynamically.

I have the MAC address of course.

TIA

Hello,

Any one using ISC DHCPserver 3.1 and Cisco CMTS and are using DHCP lease-query ?
We cant get it to work :-/

It seems like Cisco CMTS isnt using RFC 4388 standard.

Usage Guidelines

Some DHCP servers support only the RFC 4388 standard of lease query. If the DHCP server supports only the RFC 4388 standard, then you must configure the DHCP client to send a lease query according to the RFC 4388 standard.

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
