Modem Rejected by CMTS

Forums: 

Hi list,

I've a very strange problem. I was trying to set 3 different TLVs in CM config file like the below:

VendorSpecific
{
VendorIdentifier 0x000304; ( Juniper CMTS)
GenericTLV TlvCode 1 TlvLength 2 TlvValue 0x0259; (VLAN 601)

VendorSpecific
{
VendorIdentifier 0x0000ca; (Arris CMTS)
GenericTLV TlvCode 1 TlvLength 2 TlvValue 0x0259; (VLAN 601)

VendorSpecific
{
VendorIdentifier 0x000f21; (Webstar CM)
GenericTLV TlvCode 22 TlvLength 2 TlvValue 0x1b1b;
GenericTLV TlvCode 23 TlvLength 2 TlvValue 0x1b1b;
....
.... (other eMTA TLVs)

and the CMTS REJECTs the Cable Modem. When I set only two from whichever TLVs above, the modem is connecting with CMTS, but with more than three CMTS rejects it with the message:

REG REQ rejected - Message syntax error . MAC Addr: 00:0F:21:27:9B:2A

I want to know if somebody has this kind of problem, setting more than three Vendor Specific TLVs.

If somebody would be interested to know, I've fixed this problem:

The TLV's in config file should look like the following:

VendorSpecific
{
VendorIdentifier 0x000304; ( Juniper CMTS)
VendorIdentifier 0x0000ca; (Arris CMTS)
GenericTLV TlvCode 1 TlvLength 2 TlvValue 0x0259; (VLAN 601)

VendorSpecific
{
VendorIdentifier 0x000f21; (Webstar CM)
GenericTLV TlvCode 22 TlvLength 2 TlvValue 0x1b1b;
GenericTLV TlvCode 23 TlvLength 2 TlvValue 0x1b1b;
....
.... (other eMTA TLVs)

Now the modem doesn't reject by the CMTS.

I read you are using C3 with DPC2203.
We are having some delay (like 2-3 sec) in the calls, do you have any simmilar issue ?

We try with eMta Arris and all work fine.

Best regards.
