VLAN interface names must adhere to the following format: "<port name>-<vlan id>" error in wfa

[Rutul]

Issue with this is I want to give user input as Vlan Name which will be in format for ex. a0a-1111. 

When I try to execute the below command script in wfa it gives me the error as 

VLAN interface names must adhere to the following format: "<port name>-<vlan id>".

param (
[parameter(Mandatory=$true, HelpMessage="Name of the Storage VLAN ID.")]
[string]$VlanName,

[parameter(Mandatory=$true, HelpMessage="Name of the Storage Cluster")]
[string]$Cluster,

[parameter(Mandatory=$true, HelpMessage="Name of the Storage Node Name.")]
[string]$NodeName

)

Connect-WfaCluster $Cluster

$vlanname=$VlanName -Split "-"
$vlanname[0]
$vlanname[1]
New-NcNetPortVlan -Node $NodeName -ParentInterface $vlanname[0] -VlanId $vlanname[1]

But at the same time when I try to execute the last 4 lines of script in powershell It is working successfully. 

What can be the issue

Hi Rutul:

Isn't the Powershell toolkit help clarifying your doubts.

I am copy pasting the same below.

It is also available at http://localhost/wfa/wfa_docs/PoSH/Modules/DataONTAP/webhelp.C/cmdlet_New-NcNetPortVlan.html

in the machine where WFA is installed.

Let us know if it clarifies?

        Default value                
        Accept pipeline input?       true (ByPropertyName)

    -VlanName <String>
        Name of vlan interface.  The name must be of the format <parent-inteface

    -Controller <NcController[]>
        A clustered Data ONTAP controller to receive this cmdlet, as embodied by

        rentNcController is used.  In the latter case, if CurrentNcController co
        ntains a collection of NcController objects, this cmdlet is invoked on e
        ach controller in succession.

    -ParentInterface <String>
        The name of the port or ifgrp to modify.

    -VlanId <UInt16[]>
        The VLAN IDs to add.  Range: [1..4094]

Yes I have already referred that. But i found that more confusing. Example has not been given properly.  So I put another question on community on that and got resolved. This was the issue with Split function which i was using. That was creating some issue. But Then i found some alternative to that. 

Previously customer wanted to keep input as VlanName (e.g e0c-1111). So I had to split the VlanName to get the port(e0c) and Vlan ID(1111). But had an issue with splitting. It was not taking value as expected.

Instead of splitting i kept it simple as below and convinced the customer for keeping Port and Vlan ID seperate.

New-NcNetPortVlan -Node $NodeName -ParentInterface $PortName -VlanId $VlanId  -ErrorAction Stop
