Send-Trap Cmdlet

Parameters   Output Objects   Config Settings  

The Send-Trap component is used to sends SNMP traps to a remote address.

Syntax

Send-Trap [parameters]

Remarks

Depending upon the value of the Version parameter, the packet is constructed as an SNMPv1, SNMPv2 or SNMPv3 Trap PDU. The following parameters provide more control over how traps are generated: Port, Agent, Community, Enterprise.

For SNMPv3 traps, the User, AuthenticationPassword, and EncryptionPassword parameters can be set. If any values are provided in the ObjectID, ObjectType, ObjectValue arrays, they are sent unchanged. In the case of an SNMPv2 or SNMPv3 Trap, if the Obj properties are not specified, the following values are set: sysUpTime.0 equal to Uptime and snmpTrapOID.0 equal to OID.

For SNMPv2 and SNMPv3 Traps, OID must contain the full OID of the Trap. Automatic translation is handled internally from node labels to node OIDs assuming that a valid MIB file is provided. For SNMPv1, OID must be of the form "GenericTrap.SpecificTrap". These values are sent in the PDU header. Agent and Enterprise are taken from their corresponding parameters.

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.

#send a coldStart trap send-trap -manager 10.0.1.255 -oid coldStart.0 #send a custom coldStart trap send-trap -manager 10.0.1.255 -oid coldStart.0 -objectID 1.1 -objectType Integer -objectValue 20 #send a custom coldStart trap with multiple objects send-trap -manager 10.0.1.255 -oid coldStart.0 -objectID 1.1,1.2,1.3 -objectType Integer,Integer,Integer -objectValue 20,31,53

Default Value

10

Uptime Property (Send-Trap Cmdlet)

Time passed since the agent was initialized (in hundredths of a second).

Syntax

Send-Trap -Uptime int

Remarks

Uptime is used when sending SNMP traps, and it normally provides the time since the cmdlet was started in 1/100ths of a second.

If another value is desired, you may set this Uptime to a custom value. From that point on, Uptime will contain the value set plus time elapsed. Due to the nature of the cmdlet, the time elapsed should be very small.

Default Value

0

User Property (Send-Trap Cmdlet)

}

Remarks

The OID, OIDValue and OIDType fields are arrays because SNMP v2 and v3 traps may contain multiple objects.

Config Settings (Send-Trap Cmdlet)

The cmdlet accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the cmdlet, access to these internal properties is provided through the Config method.

Base Config Settings

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a cmdlet is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
MaskSensitive:   Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is true.

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.

UseInternalSecurityAPI:   Whether or not to use the system security libraries or an internal implementation.

When set to false, the cmdlet will use the system security libraries by default to perform cryptographic functions where applicable. In this case, calls to unmanaged code will be made. In certain environments, this is not desirable. To use a completely managed security implementation, set this setting to true.

Setting this configuration 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 dynamic link library (DLL) is no longer required as a reference, as all unmanaged code is stored in that file.
