Connecting a cisco firewall through putty using powershell

Question

Hi,
I have to write a powershell script to connect to a cisco firewall and execute network commands.
my code is written as mentioned below-
function plink
  [CmdletBinding()]
  PARAM
    [Parameter(Mandatory=$True)]
    [ValidateNotNullOrEmpty()]
    [string] $remoteHost,
    [Parameter(Mandatory=$True)]
    [ValidateNotNullOrEmpty()]
    [string] $login,
    [Parameter(Mandatory=$True)]
    [ValidateNotNullOrEmpty()]
    [string] $passwd,
    [Parameter(Mandatory=$True)]
    [ValidateNotNullOrEmpty()]
    [string] $command)
  & D:\PLINK.EXE -ssh $remoteHost -l $login -pw $passwd $command
  return
$remoteHost = "*****"
$login = "****"
$passwd = "******"
$command= "enable"
plink -remoteHost $remoteHost -login $login -passwd $passwd -command $command
from above script im able to login to a firewall but I am not able to enable the firewall.
Can anyone help me and provide me ways to enter the command "enable" and its password to enable firewall using powershell.

Hi Plas,
Please try the script below, which add the cmdlet "Invoke-Expression":
function plink
[CmdletBinding()]
PARAM
[Parameter(Mandatory=$True)]
[ValidateNotNullOrEmpty()]
[string] $remoteHost,
[Parameter(Mandatory=$True)]
[ValidateNotNullOrEmpty()]
[string] $login,
[Parameter(Mandatory=$True)]
[ValidateNotNullOrEmpty()]
[string] $passwd,
[Parameter(Mandatory=$True)]
[ValidateNotNullOrEmpty()]
[string] $command)
$ExePath = "D:\PLINK.EXE"
$CLine = "-ssh $remoteHost -l $login -pw $passwd $command"
Invoke-Expression "$ExePath $CLine"
$remoteHost = "*****"
$login = "****"
$passwd = "******"
$command= "enable"
plink -remoteHost $remoteHost -login $login -passwd $passwd -command $command
If there is anything else regarding this issue, please feel free to post back.
