Hello Harshit

   Because our J20(M20) is using ES-PIC for IPSec tunnel insted of AS-PIC, there's no command you mention.
We have tried with Cisco 1760 and Cisco PIX firewall which have same problem.

    I have a question about M20's IPSec behavior toward Cisco Router or Pix firewall. Becasue when IPSec tunnel
(dynamic tunnel SA) is established , if you manfully clear ipsec tunnel ( clear ipsec security association) or lifetime of 
IPSec SA expire, the IPSec tunnel will not negotiate with each other if there is no traffic going on. The only 
way to bring tunnel up is from Cisco side by using ping to trigger. It seems that we can not bring it up from 
J20's side. Do you have any idea of it ?
