Cable modem firmware upgrade

I have problem upgrading firmware on my arris CM450B.
I added flollowing lines in to modem config:

SwUpgradeFilename "CM050012_062404_EURO.img";
SwUpgradeServer 10.0.0.1;

but he modem never requests this file from tftp server.

Am I missing something?

Thanks

As stated above you need

As stated above you need Arris's CVC.

For Arris CVC the easiest way to get it is to Contact Arris and get their PacketAce Program it has the CVC preprogramed into it.

The problem is that any firmware than you want to upgrade in CM must be signed by CM vendor certivicate. So talking about you config example, there must be one more option - CVC certificate.
You can obtain such a certificate from your vendor.
Unfortunatelly I`m at home at the moment, and I don`t have any examples. Tomorrow I quote an example of Motorola firmware update config file $)

No it`s not impossible. It`s requirement of DOCSIS 1.1 specification. You`ve to obtain such a certificate from vendor or your distributor.

Here is the example of motorola config, I`ve translated it into the text file:
FileVersion = Version 6.0
03 (Net Access Control) = 1
09 (Software Upgrade File) = SB5100E-2.3.3.0-SCM00-NOSH-NNEMN.p7
32 (Manufacturer's CVC)
Organization Name: Motorola Corporation
Validity NotBefore: 010925000000Z
Validity NotAfter: 130924235959Z
Serial Number: 4d 4e 27 2d ad 34 be de 0c a1 8e 48 7c 7f 82 ca
NOTE: Informational only.
Actual file must be specified as source for giconfig.

33 (Co-signer's CVC)
Organization Name: Motorola Corporation
Validity NotBefore: 010925000000Z
Validity NotAfter: 130924235959Z
COS Serial Number: 4d 4e 27 2d ad 34 be de 0c a1 8e 48 7c 7f 82 ca

This is how it looks in config file.
If you like, I`l send compiled config to you.
