Arris CMTS 1000 / 1500 Stuff

Forums: 

Seems I'm just making one giant "LAN" as I add more and more cable users behind my 1000 or 1500. Does anyone know how to separate cable modems from others behind the Arris? Perhaps VLANs?

I've been trying to dabble into the capabilities of docsis, but it's difficult to be sure. Seems VLAN's are a feature of docsis but I do not know which version nor how to code it for the docsis 0.95 compiler.

BSR 1000 Stuff

Forums: 

Been using Arris CMTS 1000 and 1500 for some time now. Picked up a Motorola (Not River Delta) CMTS. It's a BSR 1000.

I've so far only experience operating a CMTS as a switch. The BSR 1000 appears to be only a router. As a PPPoE operator, does anyone know of ways I can make use of it?

Random modems knocked offline

Forums: 

I have a strange problem on our network. We have 4 CMTS routers: 3 Cisco and 1 Motorola 64K. The Motorola is new and only has a handful of customers on it (less than 60). Some of the modems on the Motorola are randomly getting knocked offline. What is strange is the router still sees the modem in an online state and the modem thinks it is still online (solid 'online' light) but I can't ping it. The only way to fix the problem is to power cycle the modem. If I leave the modem alone, eventually the router will see it as offline and the 'online' light on the modem will flash.

modems will not go beyond init(dr)

Having this issue on a Cisco CMTS(10K -with MC520H) running 12.3(23)BC2 - any ideas seem to only impact a particular upstream

Warpera CEMAX 800/100

Forums: 

Hello,
Anyone ever heard of a Warpera Cemax CMTS?
We have the joy of owning one here, and we cannot get it to communicate with dhcp/tod/tftp servers, nor RF, the company is belly up and no one seems to have any information on them.

The Upconverter (integrated) is a Wavecom, Cisco-like command line, and Broadwave chip sets.
Option 82 support can be enabled/disabled, tried both ways with a compatible option 82 backend, and no change/difference.

Any insight or recommendations (other than go to Cisco or Arris) :-)

Selfmade patch for docsis_server 2.0.4, pair ipaddr CPE with customer CM

Forums: 
Yesterday I wrote patch for docsis_server 2.0.4. I add something like this: - You can pair ipaddr for customer with their modem. - Even if client has new macaddr for CPE he still get their own IPaddr with new mac addr. - You can pair more then one IP CPE with one modem_macaddr - in thise case new mac addr will get IP, which was granted earliest This patch need new table in docsis_server CREATE TABLE `dhcp_pair` ( `modem_macaddr` varchar(15) NOT NULL, `ipaddr` varchar(16) NOT NULL, `cmts_vlan` mediumint(9) NOT NULL, `time` timestamp NOT NULL default CURRENT_TIMESTAMP
