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.
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 previous 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.
