      .PARAMETER Session
      Specify an UnitySession Object.
      .PARAMETER ID
      iSCSI Network Portal ID or Object.
      .PARAMETER ipAddress
      IPv4 or IPv6 address for the iSCSI Network Portal.
      .PARAMETER netmask
      IPv4 netmask for the iSCSI Network Portal, if the iSCSI Network Portal uses an IPv4 address.
      .PARAMETER v6PrefixLength
      Prefix length in bits for IPv6 address.
      .PARAMETER gateway
      IPv4 or IPv6 gateway address for the iSCSI Network Portal.
      .PARAMETER vlanId
      Ethernet virtual LAN identifier used for tagging iSCSI portal outgoing packets and for filtering iSCSI portal incoming packets.
      .PARAMETER Confirm
      If the value is $true, indicates that the cmdlet asks for confirmation before running. If the value is $false, the cmdlet runs without asking for user confirmation.
      .PARAMETER WhatIf
      Indicate that the cmdlet is run only to display the changes that would be made and actually no objects are modified.
      .EXAMPLE
      Set-UnityIscsiPortal -ID 'if_6' -vlanId 10

      Modifies the iSCSI network portal with id 'if_6'
