Hi ,
Can someone please guide me about dpdk dumpcap application with testpmd .
while running application I am getting following errors:

Have you allocated huge pages?
http://doc.dpdk.org/guides/linux_gsg/sys_reqs.html#use-of-hugepages-in-the-linux-environment
Check huge pages using ./dpdk-hugepages.py -s

First you must have a primary process running doing something.
DPDK-dumpcap is a secondary only process.

The interface you gave is not being controlled by primary process.
Use dpdk-dumpcap -D described in documentation to show the available
devices.
