Ethernet destination field cannot be updated

[ErikCoen]

I am using the IxNetwork 9.20 and a script like SampleScripts\pcapToRawTrafficItem.py

ethernetStackObj = configElement.Stack.find(DisplayName='Ethernet II')

# Uncomment this to show a list of all the available protocol templates (packet headers)
#for protocolHeader in ixNetwork.Traffic.ProtocolTemplate():
#    ixNetwork.info('\n', protocolHeader.DisplayName)

# NOTE: If you are using virtual ports (IxVM), you must use the Destination MAC address of 
#       the IxVM port from your virtual host (ESX-i host or KVM)
ixNetwork.info('\nConfiguring Ethernet packet header')
ethernetDstField = ethernetStackObj.Field.find(DisplayName='Destination MAC Address')
ethernetDstField.ValueType = 'increment'

At execution of last line, there is python error:

Hi Erik, I believe this issue is fixed with the latest Update. Can you try installing 9.20 Update 3?

[ErikCoen]

Yes, with update3, everything is working. Thanks a lot!
