Powershell VSP enable/disable port

I never used this Posh-SSH module, but reading its documentation here https://www.powershellmagazine.com/2014/07/03/posh-ssh-open-source-ssh-powershell-module/

it seems to me that Invoke-SSHCommand is sending the commands in a dedicated SSH channel within the SSH session; this is how SSH emulates the older rsh. But this mode will not work with VOSS. VOSS SSH server requires an interactive shell to be run inside the SSH channel.

So I think you will need to use the $session.Session.CreateShellStream approach from the same link above.

Juste for information, it’s perfectible but it’s working  like this:

 

#install module
#Install-Module -Name Posh-SSH -force

#create username/pw
$userName = "admin"
$password = "password"

#create $cred as secure string using $username and $password
$secstr = New-Object -TypeName System.Security.SecureString
$password.ToCharArray() | ForEach-Object {$secstr.AppendChar($_)}
$cred = new-object -typename System.Management.Automation.PSCredential -argumentlist $username, $secstr

#create ssh session to server that fired alert using $cred
$sessionSSH = New-SSHSession -ComputerName "switch_IP" -Credential $cred -AcceptKey

#set stream
$stream = $sessionSSH.session.CreateShellStream("PS-SSH", 0, 0, 0, 0, 1000)

#invokes stream to run command as sudo. gets pw from $secstr
$result = Invoke-SSHStreamExpectSecureAction -ShellStream $stream -command "enable" -ExpectString "10" -SecureAction $secstr
$result = Invoke-SSHStreamExpectSecureAction -ShellStream $stream -command "configure terminal" -ExpectString "10" -SecureAction $secstr
$result = Invoke-SSHStreamExpectSecureAction -ShellStream $stream -command "interface gigabitEthernet 3/15" -ExpectString "10" -SecureAction $secstr
$result = Invoke-SSHStreamExpectSecureAction -ShellStream $stream -command "shutdown" -ExpectString "10" -SecureAction $secstr

$stream.Read()

$id_session = Get-SSHSession 

Remove-SSHSession $id_session
