Green and blue lines indicate a vPC port channel from each of the Fabric Interconnects to both
Nexus switches.

Components used
Two Nexus 5548P switches.
Two Unified Computing System (UCS) 6120 Fabric Interconnect running 2.2(4b) software.
One 5108 UCS chassis.
Two B200M3 blades with VIC 1240 adapter running 2.2(4) software.
To perform and verify connectivity tests two blades were installed and RedHat Enterprise Linux
7.1 operating system is installed.

Configuration.
Both the vPC and portchannel configuration is using default.
Example vPC leading to UCS Fabirc Interconnect (FI) in this case bdsol-6120-05--A
Tests
Following test will be performed.
- Data link loss.
- Disruptive upgrade
- In-Service Software Upgrade (ISSU)
- Loss of peer keepalive link - mgmt0 interface in case of this topology/configuration.
- Loss of peer portchannel - Port-channel 1 in this configuration.
- Disabling vPC feature
Basic traffic flow.
A single iperf3 session is used to generate 6.5 gigabits per second of test TCP traffic to verify
frame loss during transitions.
