docsis_server NAK -- unknown docsis modem

Hi,

I am new to docsis and trying to setup docsis_server to manage a small cable system.
I was wondering if anyone has ever come accross this message and how it can be resolved. This is the message that I am getting in the sys_log from within docsis_server:
NAK -- unknown docsis modem macaddressOfmodem

I reboot the modem and it keeps sending out this message above.

And below is the state of the modem when I run show cable modem on the CMTS. (ip and mac info left out on purpose)
Interface Prim Connect Timing Rec Ip Address Mac Address
Sid State Offset Power
Cable 0/0/U0 54 dhcp(d) 1738 -8

Thanks in Advance.

I am not familiar with docsis_server though I would think that this error message means that the Mac address of the modem you are trying to have come online is not "built" in docsis_server. So it is not authorized to come online, try adding the modem to the modems table in docsis server.

Thank you for the reply. I

Thank you for the reply.

I do have it listed in the docsis_modem table in the dhcp_server database as listed below with mac address left out on purpose.

modem_macaddr ----- cmts_vlan ----- serialnum ----- subnum ----- config_file ----- dynamic_config_file ----- static_ip ----- dynamic_ip ----- config_opt
mac address ---------- 0 --------------- 1---------------- 30681-------- 1500_256.bin -- empty-------------------- 69------------ 69--------------- 10

are you sure the mac address

are you sure the mac address is in the appropriate format

there are many different ways to express a mac address in text form

i.e.
0000.0000.00a1 (cisco)
00:00:00:00:00:A1 (general)
0000000000A1 (General)

I am not familiar with docsis_server but I imagine it wants it either 00:00:00:00:00:A1 or 0000000000A1 form. try whichever one you do not have.

Thanks,
Jason
