The most common issues that prevent traffic from passing are:
- incorrect wiring of the NFVbench/TRex interfaces
- incorrect vlan_tagging setting in the NFVbench configuration, this needs to match how the NFVbench ports on the switch are configured (trunk or access port)
+
- if the switch port is configured as access port, you must disable vlan_tagging in the NFVbench configuration
- of the switch port is configured as trunk (recommended method), you must enable it
