results in traffic which needs to cross the switching portion.
Iperf3 parameters:
Server: iperf3 -s -i 1
●
Client iperf3 -c 10.37.9.131 -t 0 -i 1 -w 1M -V
●
The above parameters were picked to allow high rate of traffic and easy to spot packet loss.
TCP window is clamped to avoid data bursts iperf is know for. Allowing iperf to run
unclamped could result in occasional drops in ingress buffers along the path - depending on QoS
configuration. The above parameters allow for a sustained rate of 6-7 Gbps without frame loss.

To verify we can check cumulative rate of traffic on interfaces.

30 seconds input rate 5612504 bits/sec, 9473 packets/sec
30 seconds output rate 7037817832 bits/sec, 578016 packets/sec
input rate 5.60 Mbps, 9.38 Kpps; output rate 7.01 Gbps, 576.10 Kpps
30 seconds input rate 7037805336 bits/sec, 578001 packets/sec

input rate 7.01 Gbps
, 575.71 Kpps; output rate 6.56 Mbps, 9.79 Kpps
The above output shows 7 Gbps of traffic entering on interface Ethernet 1/2 and leaving on
interface Ethernet 1/1.

Data link loss
This test is designated to test how data will behave if a link which is part of vPC is shut down.
This example will use Ethernet 1/1, the output interface for data traffic, it will be shut down using
command line.
