Connect all the ports with the SFP+ optics with TX and RX shorted. • nputool -i -t 5 -T cpu_self • nputool --init --test 5 --traffic cpu_self CPU traffic for uplink ports connected between adjacent ports Traffic is sent from the CPU internally generated packet to the front-end Dell EMC SFP+ ports which are connected with SFP+ optics using a cable. Connect the SFP+ ports with the Dell EMC SFP+ optics using cables. • nputool -i -t 5 -T cpu_adj • nputool --i --test 5 --traffic cpu_adj IXIA traffic with external loopback Traffic 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 first 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 Configure the VLAN and display the BCM.0> shell. To verify the counters, use the show c command in the BCM shell. IXIA traffic with adjacent ports connected to IXIA Traffic 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 Configure 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 For example: root@dell-diag-os:~# nputool --init --test 2 DMA pool size: 16777216 PCI unit 0: Dev 0x8375, Rev 0x11, Chip BCM88375_B0, Driver BCM88375_B0 sysconf_probe successful global_sal_config successful *** 1 BCM devices are detected Diag NPU initialization over Test link_status_test for NPU 0 SKIPPED

CPU
traffic
for uplink ports connected between adjacent ports
Traffic
is sent from the CPU internally generated packet to the front-end Dell EMC SFP+ ports which are connected with SFP+ optics
using a cable.
Connect the SFP+ ports with the Dell EMC SFP+ optics using cables.
•
nputool -i -t 5 -T cpu_adj
•
nputool --i --test 5 --traffic cpu_adj
IXIA
traffic
with external loopback
Traffic
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
first
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
Configure
the VLAN and display the

shell. To verify the counters, use the
show c
command in the BCM shell.
IXIA
traffic
with adjacent ports connected to IXIA
Traffic
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
•

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
