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.
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.
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
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.
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.
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.
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?
