Specifications

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.
Default pre-emphasis for Port-1 (ce0) and Port-2 (ce1) connected to IXIA:
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.
