Add multiple SNMP traps destination locations

I'm trying to set multiple SNMP trap destinations, but can't seem to get the correct format.

Any ideas?

#Set Variables

$communities="R3@d0nly"

$trapDestinationA="1.1.1.1"

$trapDestinationB="1.1.1.2"

Connect-VIServer server1

$vmhosts= @(Get-VMHost) | sort

foreach ($vmhostin$vmhosts)

{

Write-Host"Conecting to $vmhost"

$esxConnect=  Connect-VIServer-Server$vmhost-Userroot-Password"password"

#Get SNMP Object

$snmpObj=Get-VMHostSnmp

if(!((Get-VMHostSnmp).Enabled))

{

      Write-Host"Enabling SNMP"

      Set-VMHostSnmp-HostSnmp$snmpObj-Enabled:$true-ReadOnlyCommunity$communities

}

Else

{

      Write-Host"SNMP Already Enabled"

}

Write-Host"Setting SNMP Configuration"

Set-VMHostSnmp-HostSnmp$snmpObj-ReadOnlyCommunity$communities

Write-Host"Setting the new SNMP targets"

Set-VMHostSnmp-HostSnmp$snmpObj-AddTarget-TargetCommunity$communities-TargetHost$trapDestinationA

Set-VMHostSnmp-HostSnmp$snmpObj-AddTarget-TargetCommunity$communities-TargetHost$trapDestinationB

Write-Host"Disconnecting from $vmhost"

Disconnect-VIServer$esxConnect-Confirm:$false

}
