Hi Ajit,

Ping again in case if you miss the last email.

Did you have a chance to give it a try on login to the machines?

Just some notes, we are currently running compile and some
performance/functional testing.
Which it may be hard for you to run dts, so please let me know if you want
me to stop these tests for you to debug.

Step I run:
CONF="conf_dpdk" ./switch.sh Broadcom   #this is to switch the
dts configuration to Broadcom
./dts -s                                                           #To
start the dts

Informatio:
arm-dell.dpdklab.iol.unh.edu
- dts - located in /opt/dts
- Trex - located in /opt/trex/v2.87

arm-gigabyte.dpdklab.iol.unh.edu
- dpdk - located in /root/dpdk

Best,
David
