Set-SNMP Cmdlet
Parameters Output Objects Config Settings
The Set-SNMP component exposes functionality to PowerShell to send SNMP SET requests.
Syntax
Set-SNMP [parameters]
Remarks
Managing SNMP agents directly from Powershell by changing OID values of remote agents is as easy as setting a few parameters.
Version allows the user to specify the version of SNMP to use, v1, v2 and v3 are supported. If v3 is selected, the User and AuthenticationPassword parameters can be set to authenticate to the agent before changing the OID value, and EncryptionPassword can be used to enable SNMPv3 encryption. The OID is specified by OID and the new value is specified by OIDValue.
The cmdlets support pipeline input for some of their parameters. Prebuilding an object and piping it to the cmdlet is very useful, but should be used with caution to prevent security conflicts. Steps have been taken to decrease the risk of a possibly accidental pipe to the cmdlet, for instance, the Credential parameter cannot be piped to the cmdlet and must be specified manually.

This setting only works on these cmdlets: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.
Setting this setting to true tells the cmdlet to use the internal implementation instead of using the system security libraries.
On Windows, this setting is set to false by default. On Linux/macOS, this setting is set to true by default.
If using the .NET Standard Library, this setting will be true on all platforms. The .NET Standard library does not support using the system security libraries.
Note: This setting is static. The value set is applicable to all cmdlets used in the application.
When this value is set the product's system DLL is no longer required as a reference, as all unmanaged code is stored in that file.
