Specifications

Trac is sent from the CPU internally generated packet to the front-end SFP+ ports which are connected with the Dell EMC SFP+ optics
using a cable.
Connect the rst port to IXIA and all other ports with Loopback optics.
• nputool -i -t 5 -T ixia_self -d
• nputool --init --test 5 --traffic ixia_self -d
Congure the VLAN and display the BCM.0> shell. To verify the counters, use the show c command in the BCM shell.
IXIA trac with adjacent ports connected to IXIA
Trac is sent from the CPU internally generated packet to the front-end ports which are connected with DACs or optics using cables
connected top-to-bottom.
Connect two ports to IXIA with SFP+ optics and cables.
• nputool -i -t 5 -T ixia_adj
• nputool --init --test 5 --traffic ixia_adj
Congure the VLAN and display the BCM.0> shell. To verify the counters, use the show c command in the BCM shell.
PRBS for QSFP ports
Connect ports with Loopback cables and run the PRBS MAC and EXT Loopback tests.
• PRBS MAC level test nputool –i –t 2 or nputool --init --test 2
• PRBS EXT level test nputool –i –t 3 or nputool --init --test 3
