Docsis chat

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.

Do any of yall have any BSOD services that pass tagged traffic through the modem upstream to the CMTS. So far I have only found 1 modem (SB6121) that passes the single tag with no issues in my testing. I have tried an Arris CM820 (fw=110a) but it drops the vlan tag randomly, with packet size varying from 100 bytes to 1500 bytes. Ticket currently open with Arris on that. I have also been unsuccessful with bridging any router modems and passing tagged traffic as well (SBG6580, DG860). I may be missing something in the configuration on those.

Dear All,

I just read:

Is there anybody with access to the latest Firmware for the Cisco EPC3212 fixing this?

thanks
Oliver

Hello, not sure if anyone can help me I am using CNR 8.1.3 and Packet Ace, Im not a pro but know my way around, I was able to get the internet side of the Arris TM822 to work however the MTA side I am stuck, it seems that the tftp server it is pointing to is the wrong one, however in cnr i have it set to the correct servers. the mta is stuck in telephony tftp and i can not get it to work please help

Dear all,

we do urgently need the latest Firmware for the Cisco EPC 3212. Right now we got:

SNMPv2-MIB::sysDescr.0 = STRING: Cisco EPC3212 EuroDocsis 3.0 2-PORT EMTA
HW_REV: 1.0; VENDOR: Cisco; BOOTR: 2.3.0_R1; SW_REV: EPC3212-P10-5-v302r125531-101220c; MODEL: EPC3212

If possible I would prefer the SIP-Version.

It would be great if someone could help me out with that.

thanks in advance

Oliver

Hi Lee,
Thanks so much for the response. How would I go about finding the album version? And I'm not totally sure when it was last serviced, but it's a matter of years not months.
Thanks,
Sean

I typically see downstream DOCSIS channels in the 500-700MHz range and was wondering if this is because of best practice or some other reason? We're considering giving our frequency space a new home, ~200MHz

Hello,

I am using MOTOROLA SVG1501E but it does not create dynamic service flow for MTA. When the call is on it does not create any UGS scheduler type service flows.
Instead Thomson cable modems can do it. I am using CASA C3200 cmts-s.

Is there any configuration to change in config file?
