Powershell query for SSL Client profile

I believe you'll need to pass the virtual server name to the get_profile() method. Something like this:

$vips = (Get-F5.iControl).LocalLBVirtualServer.get_list()
ForEach ($vip in $vips){
    $profiles = (Get-F5.iControl).LocalLBVirtualServer.get_profile($vip)
    If ($profiles){
        write-output "Virtual Server: $Vip"
        Write-Output "Profiles: `r`n " + $profiles
    }
    Write-Output "-----"
}
