AllowUnecrypted WinRM Property

Question

Hi all,

I am using HyperV.

I need to understand the configuration of WinRM for using different communication channels and the encryption of the communication. 

I understand the creation of HTTP/HTTPS listeners. What I don't understand is what is controlled by the AllowUnencrypted property. Docs says:

===

AllowUnencrypted - Allows the client computer to request unencrypted traffic. By default, the client computer requires encrypted network traffic and this setting is False.

===

But what exactly that means, do we forbid usage of HTTP if 'AllowUnencrypted = false'? Obviously not, because I am able to communicate without HTTPS listener. So, obviously we have some kind of encryption that is done for the communication over HTTP. Some more details about what exactly encryption is being done would be helpful.

What happens if 'AllowUnencrypted = true'? I stumbled upon an article in the web which said that only the SOAP will be unencrypted in this case, but some more details would be helpful.

Thanks in advance,

We want to set AllowUnencrypted to true.

On W2K8 we used to be able to run:

winrm set winrm/config/Client @{AllowUnencrypted = "true"}

On W2K12 (Beta) we're getting the error:

Error: Invalid use of command line. Type "winrm -?" for help.

Many variations of this command have been tried to no avail.

The "get" command works:

PS C:\Users\Administrator.ENGSMOKE> winrm get winrm/config/Client
Client
    NetworkDelayms = 5000
    URLPrefix = wsman
    AllowUnencrypted = false
    Auth
        Basic = true
        Digest = true
        Kerberos = true
        Negotiate = true
        Certificate = true
        CredSSP = false
    DefaultPorts
        HTTP = 5985
        HTTPS = 5986
    TrustedHosts

Suggestions would be welcomed.
