Why does Spirent TestCenter indicate an error message "Interface IPv4 17 has invalid Network Stack." ?


Logs indicate:

4:23:23,286 ERROR 9        -       - Interface EthIIIf: Multicast MAC address is not allowed for emulated devices (Device 1)

14:23:23,286 INFO  9        - user.event         - Interface IPv4 17 has invalid Network Stack. Please see log for details


This means one of the Device Blocks source MAC is configured as multicast which is not allowed.


Example MACs:

01:10:94:00:00:01 (multicast MAC, not allowed)

00:10:94:00:00:01 (non-multicast, good)
