I am assuming that you are looking to do this with UCSM.  If that's the case then here is a sample script that accomplishes what you want.  Ping me if you have any questions on it. clear Write-Output "Script Running..." Import-Module CiscoUcsPs -ErrorAction Stop Disconnect-Ucs $MyUcs = "1.2.3.4" #IP or DNS of UCSM VIP $ServiceProfile = "ServiceProfile1" #Name of service profile to gather data from" $Nic = "vnic0" #Name of NIC to gather info about $Cred = Get-Credential -UserName "admin" -Message "Enter UCSM Login Credentials" $MyCon = Connect-Ucs -Name $MyUcs -Credential $Cred if ($MyCon) {   Write-Output " Login Successful" } else {   Write-Output "Login Failed"   Write-Output " Exiting..."   exit } $PxeNic = Get-UcsServiceProfile -Name $ServiceProfile | Get-UcsVnic -Name $Nic if (!$PxeNic) {   Write-Output ""   Write-Output "Failed to gather requested NIC information"   Write-Output " Exiting..."   Disconnect-Ucs   exit } Write-Output "" Write-Host "PXE NIC Information-" -NoNewline $PxeNic | ft -AutoSize -Property Name, Addr, BootDev Write-Output "Script Complete" Disconnect-Ucs ...

Bala, PowerShell is a Microsoft scripting language.  Thus it must be run from a Windows Machines.  My scripts are written to support PowerShell v3 and above so you'll need to run Windows 7 or above for a client OS or Server 2008R2 or above for a server instance to be able to get V3.  You will also need to download and install the Cisco PowerTool PowerShell library for UCS.  That can be downloaded from www.cisco.com under the downloads section by searching for PowerTool.  Download the latest.  The machine to run the script from must have network access to your UCS system(s).  Once you have that setup you will need to enable PowerShell on your workstation/server where you are executing the script from and have installed PowerTool.  To do this open a PowerShell window and enter: set-executionpolicy unrestricted -force.  Now you can run PowerShell scripts.  Download the Get-UcsWwpn script from communities, extract it into a folder of your choice and then go to that folder and execute it by entering .\get-ucswwpn.ps1 and press enter.  Follow the information and prompts from the script and it will generate the file of the WWPNs for you.  This particular script requires Excel to also be installed on the machine where you are running the script.  You will see any pre-req's in the script as you execute it. Beyond that I would suggest doing some searching on the Internet for search items like "introduction to powershell" and "learning powershell" to learn more. ... View more

The script is run from a workstation that has network access to the UCS.  It is a PowerShell script.  The workstation requires Powershell v3 or above and the installation of the Cisco PowerTool.  PowerTool is the PowerShell module for UCSM.  It can be downloaded for free from cisco.com.  Just go to the downloads section of cisco.com and search for PowerTool and download and install the latest. ...

Scott, Thanks for the feedback on the script.  The way I wrote it would make it difficult to add this capability.  If I see others requesting such a feature I would consider it, but in the meantime, all of my scripts are provided so that your or your organization can use them as examples to customize for their needs.  Good luck and if you decide to tackle modifying the script and have any questions, please reach out to me and I will assist in any way I can. ...

Those should work.  I'm sorry but I don't know 'why' this isn't working for you.  Can you confirm that you can open the UCSM GUI through the web page? ... View more

I looked over my script and I cannot reproduce the issue you are having.  I even upgraded by PowerTool module to the same version.  I can only ask a few questions. 1 - What version is the UCSM? 2 - What version of Java do you have installed? ... View more
