Equipment cannot be added in cvp. Please tell me the solution.
I attach the log.

If the device cannot stream to CVP (on TCP 9910) the onboarding will fail. There are a few things you can check:

    • there's no firewall blocking the communication between the switch and CVP on TCP port 9910
    • to test if this works as expected you can run: telnet x.x.x.x 9910 in EOS and see if it connects successfully (note that you have to run this without specifying /source-interface flag
      if the above is validated, you'll have to check the TerminAttr logs, either by running show agent TerminAttr logs or by going to bash and checking the logs in /var/log/agents/, a quick way to do that is to run bash cat /var/log/agents/TerminAttr-`pidof TerminAttr`, that should give you a good indication on what's wrong
    • in case there's no FW in between and the telnet command will fail to connect, it could mean that you are using in-band management, in which case you'll have to set the telnet source and also the -cvsourceip=x.x.x.x

flag in TerminAttr.

To automatically set the cvsourceip upon registering you can follow the steps from
