Docsis chat

I haven't found much information on this so far, I was wondering if it was possible to setup a static Internet IP address to a CPE directly into a specific CM configfile?

Hi All,

I have few questions on understanding of docsis.

1. As we know, CMTS uses Downstream to send packets to CM. How does the single instance of packet sends to multiple CM. At which place these packets get duplicated.

2. Also how does the specific packets (channel) are served to some CM. (eg paid channel, on demand TV), Since Downstream will send the packets to all CM.

Hi there,

I'm playing around with an UBR10k (ubr10k4-k9p6u2-mz.122-33.SCF3.bin). I wonder if anyone knows what are the RCP IDs that this brand of CMTS support without any additional RCC configuration???

What I specifically want to know when should I write an RCC template and when to expect tha default RCP IDs to work.

Best Regards

The Arris cable modems has what they refer to as "smart download" for their firmware updates, where the device will just download the differences between it's current firmware and the required firmware update.

Are some tftp-hpa specific options in it's configuration to support this feature?

Dear;

             I have a arris mta tmg-602a with disabled phone and noticed consumption in downstream rf interface even with no ethernet cable connected (see attached file). is that consumption is real? will be some error in my monitoring software?

best regards, Flavio.

Hello All,

I know very little about CMTSs and was hoping someone could clue me in on how I would determine the Album version on a Nortel 1000.

Cheers,

I am using CISCO ubr7246vxr with updated software.

Does running this command everyday 'Clear cable modem offline delete' help the CMTS? Somebody is telling me it would be beneficial to do this every hour and it allows more modems to lease. My argument is that lease time only depends on the 15 minute lease I have set up in the policy. this person is contenting that the offline modems still use up the IP address in case they get plugged in before 24 hours is up ( offline modems get removed every 24 hours automatically).

I have a CISCO DOCSIS 2 ubr system with 4 D.S ports available and 16 Upstream ports available. I need to setup a system so that the 400 modems download at maximum speed. The 300 modems keep getting replaced with another 300 modems- this is a production plant where the modem is downloading firmware.

i have cisco UBR 7246 router having MC88v line card , Mc88v card having two physical Downstream port.

every physical DS port having four logical channel with different center fre.

now the problem i am facing is modems are not equally balance among the four logical channel of same DS.

so any one plz suggest to do load balance config on my Box.

Hello , I'm kind'a new to this forum :)

So thing is :

I have this two lines in my conf file :

SwUpgradeServer
SwUpgradeFilename

Thing is I have modems EPC 2203,2202 and 3x series , is there a way to multiple update, way that it recognize which modem it is and update it's fw.

Some thing like

SwUpgradeServer x.x.x.x
SwUpgradeFilename "epc 2202.bin"
SwUpgradeFilename "epc 2203.bin"

Do I have to use CMSoftwaretable something like CmSwModel....

Or just adding another MfgCVCData will fix tha thing.
