Hi
I am having some issues with our 2 Arris C3. Since 2 months ago randomly some upstream port hang up, showing the snr value, buy 0 for mer, and of course all the modem go down. If I shut and no shut the port nothing happened, only reload solve the issue.

Any Ideas ?

I have suspect about noise in the lines, but the thing about reload is very annoying.

Thanks !
PS I Already open a case with our local Arris Support.

I have a Cornerstone 1000 have I have several different modem vendors the system will not register their DHCP offered IP addresses with. THe DHCP server is an Centos 5.3 w/ ISC DHCP 3.05;

The problem vendors are:
00:10:95:xx:xx:xx
00:0f:9f:xx:xx:xx
00:90:64:xx:xx:xx

I know the DHCP server is working because I see the leases on MAC's 00:50:da:xx:xx:xx.

The owner of this CMTS stated that previously the netadmin had to create a "wildcard" and this resolved the issue... Please anyone with ANY advice please chime in...

It appears from the debug from the CMTS:

Hi All,

With Arris C3 cmts if configured at 64Qam modulation with how many users/customer can allocate the whole downstream bandwidth?

cheers,

Looking for documentation on CNR 5.5 for Windows. Cant find anything at Cisco website, obsolete product.

So .. I have like .. tons of errors on input/output on the FA interface .. also input errors on the cable interfaces .. and same thing on the catalyst switch to which 2 VXR's are connected... the FA's in the ubr's are in halfduplex mode because they'd work like crap if in full duplex .. I think because it wouldn't face the traffic ?:| .. currently I have 2 ubr's with the cable interfaces ( with 6 upstreams ) all of them having > 50 && < 200 users .. ( I could post real numbers if needed ) ...

Can someone please send me or expalin why RF upstream plant SHOULD NOT be balanced with a DOCSIS test feature on any meter that has this application.Also explain why RF upstream plant /Downstream RF plant should always be balanced with a good sound sweep system ( WHICH I HAVE BUT IS NOT USED).PM techs are not using the sweep to balance upstream plant and they must stop using the DOCSIS Test feature to perfom this task...........Someone please send me the technical reasons why so I can stop this from occuing in our plant.Headend and Hubs are secured where unity gain is concerned to all servi

Also if anyone knows the OID for S/N on a specfic upstream card and active modem count that would be great too.

Thanks!

Hi list!

How cable modems reserve bandwitdh on the cmts? I mean when a cable modem gets an ID from the cmts, this means that automatically reserves bw for it?

Hope I explain myself

Thanks in advance

Someone can guide me on how I can set up a limited user for a BSR2000, eg: the uesr can't restart the CMTS in enabled mode.

Thank you very much

Anyone know what OID or MIB will allow SNMPset or SNMPwalk to restart a cable modem via a NORTEL CMTS 1000 using the modem mac address only? I need to command that modem restarts via mac address and not ip address over SNMP on my network.
