Communication problem between MSM760 + IMC

[johnk3r]

Hi !

Need to manage MSM760 by IMC. I have the Wireless Services Manager Module, IMC and MSM760 Controller updated.

Configured SNMP and SSH on the Controller and I can already see information from APS, Customers, SSID by IMC. The LAN and WAN interfaces are active in the SNMP configuration.

Added the IMC IP in the "Management Console" of the Controller, the status is "Connecting". I made the configuration as the video: https://www.youtube.com/watch?v=BP8NLucAvqY

Any suggestions?

Hi !

I'm still trying to find the cause of the problem. Checked in MSM760 system logs the error below:

MSM with this software version 6.5.0. Any suggestions?

Hello!

You have to allow TCP port 7668 on IMC server's firewall or on other firewalls which You have between that nodes.

At least, it was solution in my case.

Hi !

In my case it would not be the problem. In my firewall is released communication between IMC vs MSM. And I can see the Controller's request on port 7668 in the IMC server.

The problem is the certificate Go Daddy used in communication between the MSM760 and IMCI. I changed to the default certificate and communication work.
