IXIA trac with external loopback
Tests the trac sent from IXIA to port-1 and to the front-end ports which are connected with external Loopback optics.
Connect the rst 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 congure the virtual local area network (VLAN) and after the BCM.0> shell displays, send the trac from IXIA. To verify
the counters, run the
show c command in the BCM shell.
IXIA trac with adjacent loopback
Tests the trac sent from IXIA to the front-end ports which are connected with DACs or optics with cables connected top-to-bottom.
Connect the rst 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 previous commands congure the VLAN and after the BCM.0> shell displays. To verify the counters, run the show c command in the
BCM shell.
CPU trac with external loopback for uplink ports (SFP+)
Trac 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 trac for uplink ports connected between adjacent ports
Trac 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
