Hello, I have Motorola SVG2500E with SIP firmware i I can't force mta to work.
Modem gets good (I think) dhcp 122 option's, MTA is trying to get IP but it's no ACK from modem :/.
What can be wrong?
It's my 122 option dump:
To cm:
Option: (t=122,l=6) CableLabs Client ConfigurationCableLabs Client Configuration (6 bytes)
Option: (122) CableLabs Client Configuration
Length: 6
Value: 010450918087
Suboption 1: TSP's Primary DHCP Server: A.B.C.D (4 bytes)
End Option
and to MTA:
Option: (t=122,l=21) CableLabs Client ConfigurationCableLabs Client Configuration (21 bytes)
Option: (122) CableLabs Client Configuration
Length: 21
Value: 030501509187820801FF0609054241534943013100
Suboption 3: TSP's Provisioning Server: A.B.C.D (5 bytes)
Suboption 8: TSP's Provisioning Timer Value: 255 (1 byte)
Suboption 6: TSP's Kerberos Realm Name: BASIC.1 (9 bytes)
End Option
A.B.C.D its my dhcp/tftp server ip.
What's wrong?
I have not worked with this modem before are you sure it uses SIP technolgy, and not packetcable (with NCS signaling)..... I was not aware that motorola had released a SIP modem in any form, they have been promising one (or firmware for their current modems) forever....
Anyway, back to your question, the info you have there looks right, however MTAs will not acknowledge the DHCPOFFER unless they have a FQDN. This means you need to send a hostname (the mac address of the MTA works well) option and a domain name (I believe this has to be a valid resolving domain name) option. However, DNS resolution of the FQDN is not required..
i,e, a FQDN for a MTA with mac 001122334455 could be
001122334455.mta.domain.com
I'm trying Scientific Atlanta EPC2203 and have the same problem too :(.
My motorola have SVG2500E-2.1.8.0-GA-00-SH firmware. It should be SIP (my provider told that :)
OK, i got IT :) hostname(mac).domain. I have ack, now tftp fight :D
In what parameter i should write ip addres of tftp server
hard to say without knowing what dhcp server your using (they all call it something different) i.e. DHCPD calls the two possible options next-server and tftp-server, Cisco CNR calls them tftp-server and packet-siaddr, but generally speaking you need option 66 and/or option option 150
main difference is option 66 only allows one server IPs, option 150 allows multiple.
Most new modems prefer option 150 but I still put both in anyways, since it does not hurt.
if you use isc dhcp , you set like this ?
option tftp-server-name "10.200.200.254"; --> can be DNS
next-server 10.200.200.254; --> only IP Address
but as i remember , only work next-server for emta
