CPU Traffic with Adjacent Loopback
Tests the traffic sent from the CPU internally generated packet to the front-end ports which are connected with direct attach
cables (DACs) or optics with cables connected top-to-bottom.
Connect all the ports with DACs or 40G/100G optics with cables.

IXIA Traffic with External Loopback
Tests the traffic sent from IXIA to port-1 and to the front-end ports which are connected with external Loopback optics.
Connect the first port to IXIA and all other ports with QSFP28 Loopback optics.
• nputool -i -t 1 -T ixia_self -d
• nputool --init --test 1 --traffic ixia_self -d
These commands configure the virtual local area network (VLAN) and after the BCM.0> shell displays, send the traffic from IXIA.
To verify the counters, run the show c command in the BCM shell.
IXIA Traffic with Adjacent Loopback
Tests the traffic sent from IXIA to the front-end ports which are connected with DACs or optics with cables connected top-to-
bottom.
