How to - CDP Network Mapping?

[filipsmeets]

I'm trying to set multiple network mappings for a CDP Policy using the Set-VBRCDPPolicy command.

Code: Select all

Connect-VBRServer

Connect-VIServer vcenter -Credential

$CDPPolicy = Get-VBRCDPPolicy -Name "CDP"

$SourceServer = Get-VBRServer -Type ESXi -Name 'dc1-esx'
$SourceNetwork = Get-VBRViServerNetworkInfo -Server $SourceServer

$TargetServer = Get-VBRServer -Type ESXi -Name 'dc2-esx'
$TargetNetwork = Get-VBRViServerNetworkInfo -Server $TargetServer |Where-Object{$_.NetworkName -like 'DRP*'}

$AllmyObject = @()


foreach($t in $TargetNetwork){
    $Name = $t.NetworkName.ToString().Substring(4)
    
    $s = $SourceNetwork | Where-Object{$_.NetworkName -like "$Name"}

    if(($null -ne $s) -and ($s.NetworkName -notlike '*TRUNK*')){
        
        $myObject = [PSCustomObject]@{
            SourceNetwork = $s
            TargetNetwork = $t
        }
        $AllmyObject += $myObject        
    }
}

$VBRCDPPolicyArg = @{
    Policy = $CDPPolicy
    SourceNetwork = $AllmyObject.SourceNetwork
    TargetNetwork = $AllmyObject.TargetNetwork
}

Set-VBRCDPPolicy @VBRCDPPolicyArg

Set-VBRCDPPolicy : Unable to validate network mapping configuration: the same network Source network: DC1-DVS-Workloads is specified as source and target

Hi Filip,

When mapping source and target networks with Add/Set-VBRCDPPolicy cmdlets, members of network arrays are correlated by index: sourceNetwork[0] => targetNetwork[0], sourceNetwork[1] => targetNetwork[1] etc. So, the message you see is reflected if the source network at a given index is the same as the target network at a given index.

Thanks,
Oleg

Hi Oleg

Thx for reaching out.
They don't seem similar to me.

PS E:\Scripts> $AllmyObject.SourceNetwork[0]

We changed the script as follow but are getting another error.

Code: Select all

Connect-VBRServer

Connect-VIServer vcenter -Credentials

$CDPPolicy = Get-VBRCDPPolicy |Where-Object{$_.Name -like '*gold*'}

$SourceServer = Get-VBRServer -Type ESXi -Name 'dcr1-esx-p021'
$SourceNetwork = Get-VBRViServerNetworkInfo -Server $SourceServer

$TargetServer = Get-VBRServer -Type ESXi -Name 'dcr2-esx-p011'
$TargetNetwork = Get-VBRViServerNetworkInfo -Server $TargetServer |Where-Object{$_.NetworkName -like 'DRP*'}

$SrcNet = @()
$TrgNet = @()

foreach($t in $TargetNetwork){
    $Name = $t.NetworkName.ToString().Substring(4)
    
    $s = $SourceNetwork | Where-Object{$_.NetworkName -like "$Name"}

    if(($null -ne $s) -and ($s.NetworkName -notlike '*TRUNK*')){
        
        $SrcNet += $s
        $TrgNet += $t
                
    }
}

$VBRCDPPolicyArg = @{
    Policy = $CDPPolicy
    EnableNetworkMapping = $true
    SourceNetwork = $SrcNet
    TargetNetwork = $TrgNet
}

Set-VBRCDPPolicy @VBRCDPPolicyArg

We are now getting the following error. The command is not accepting $CDPPolicy.

Set-VBRCDPPolicy : Object reference not set to an instance of an object.

We tested the same with a Replication Job and there it works.

Hi Filip,

Sorry my answer took so long. Couldn't get ahold of a lab with CDP enabled immediately.
Tested your case though and couldn't reproduce any of the errors you encountered. Powershell does throw an error when trying to map the network to itself, but in other scenarios I could get CDP policies modified and working using your script sample. I would advise to contact our support and submit logs for further investigation. Please, also share the case id here so that we could follow it up.

Thanks,
Oleg
