Connect the first two ports to IXIA and all the remaining ports with DACs or 40G/100G optics with cables.
• nputool –i –t 1 –T ixia_adj
• nputool --init --test 1 --traffic ixia_adj
The above commands configure the VLAN and after the BCM.0> shell displays. To verify the counters, run the show c
command in the BCM shell.
CPU Traffic with External Loopback for Uplink Ports (SFP+)
Traffic is sent from the CPU to the SFP+ ports.
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 SFP+ ports which are connected with SFP+ optics
using a cable.
Connect the SFP+ ports with the Dell 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 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:/opt/ngos/bin# nputool -i -t 2
