Do the parameter attributes change the powershell script file somehow?

Question

I use the net-snmp extension functions to be able to run the powershell script when requesting a specific SNMP file.

snmpd is configured to run get-storageinfo.ps1 script with some parameters.

The script is called by the net-snmp agent as follows:

& c:\scripting\get-storageinfo.ps1 -name somedevicename -detaillevel 2 -oid oidstring

However, when I add parameter attributes or CmdletBinding (or both), my parameter definitions in my get-storageinfo.ps1 script change. I do not understand why. I have this at the very top of my script (after some comments actually).

[CmdletBinding()]
Param(
[string]$name,
[string]$detaillevel
[string]$oid
)

or same problem

Param(
[Parameter(Mandatory=$True)][string]$name,
[string]$detaillevel
[string]$oid
)

This somehow breaks my snmpd functions. When the configured OID is read, I get: "There is no such instance in this OID"

( ) , CmdletBinding :

Param(
[string]$name,
[string]$detaillevel
[string]$oid
)

"Has CmdletBinding: $(Test-Path Variable:\PsCmdlet)"
"name             : $name"

PS> & '.\NoCmdletBinding.ps1' -name somedevicename -detaillevel 2 -oid oidstring FourthArg

Has CmdletBinding: False
name             : somedevicename
detaillevel      : 2
oid              : oidstring
args.Count       : 1

CmdletBinding.ps1:

[CmdletBinding()]
Param(
[string]$name,
[string]$detaillevel,
[string]$oid
)
"Has CmdletBinding: $(Test-Path Variable:\PsCmdlet)"
"name             : $name"

"oid              : $oid"
"args.Count       : $($args.Count)"

# Passing a 4th arg to an advanced function throws an error
PS> & '.\CmdletBinding.ps1' -name somedevicename -detaillevel 2 -oid oidstring

Has CmdletBinding: True
name             : somedevicename
detaillevel      : 2
oid              : oidstring
args.Count       : 0
