Dear all

MX960 18.4R3.3
Could someone help me with setting ERX-LI-Action settings by CoA?

I am trying to send the following CoA but get an error

User-name = "dhcp.50d4.f796.5c8b"
ERX-LI-Action = 1
ERX-Med-Dev-Handle = 1111
ERX-Med-Ip-Address = '192.168.25.1'
ERX-Med-Port-Number = 12001

I get the error

Received response ID 141, code 45, length = 26
Error-Cause = Invalid-Request

Thank you for any help!

Hi, ERX-Med-Dev-Handle should be in HEX. Try to set it as 

ERX-Med-Dev-Handle = 0x1111

Thank you for your reply.

But without success. The same error.

Also, in the documentation, I see that ERX-Med-Dev-Handle is a string value

Can you confirm these 

1) is subscriber-secure-policy license installed ? 

2) is "services radius-flow-tap" configured (at least vt interface and source address) ? 

Thank you that you pointed me to the license. I do not have it.

But, maybe you can help me with another question which I asked before here
