Unable to decode JSON - Commands executed locally instead of on switch

[jnm27]

SUMMARY

I am trying to use the aruba module with network_cli and am unable to run aruba_config on it. Looking through the code, it appears that it is calling exec_command from the base connection plugin, which simply calls the local connection plugin. So I don't see how it would work. Maybe I am wrong though.

Hello, check this #405 looks like the same issue. I found that this happens when using Libssh as Connection Plugin. By changing it and falling back to Paramiko, it has worked again. This can be done by setting this in the ansible.cfg file:

[persistent_connection] 
ssh_type = paramiko
