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. For the S5148F-ON switch, to verify the counters, run
the
show c
command in the XP 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. For the S5148F-ON switch, to verify the counters, run the
show c
command in the XP 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 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. For the
S5148F-ON switch, to verify the counters, run the
show c
command in the XP 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.
