I am trying to run the basic forwarding sample application with following
arguments
sudo ./build/basicfwd -l 1 -n 4
The error says number of ports must be even
By ports does it mean by number of nic in my system?

In many cases, yes. However, some some nics have multiple ports/interfaces on
them. Testpmd, and some other sample apps, don't have this restriction -
the basicfwd app does just to keep the code as short and as simple as
possible.
