[strongSwan] dpd not getting triggered

[Kalyani Garigipati (kagarigi)]

Hi,

I am using strongswan version 5.6.1
I found that even though I configured dpd using dpddelay and dpdtimeout, dpd is not getting triggered from strongswan client at all even though there is no traffic passing.
Please let me know how to debug this.

         charondebug=all
        # crlcheckinterval=600
        # strictcrlpolicy=yes
        # cachecrls=yes
        # nat_traversal=yes
        # charonstart=no
