Hi,Neale , Radu and Fan Now the ipsec in VPP did not record the traffic timestamp in sa and spd like linux kernel . So we can not Implement the full DPD function In IKE control daemon that only send DPD when no traffic . What is the good method to add timestamp . This method should be fit to both sync node and async mode. Use a new timestamp counter or add timestamp in old couter ipsec_sa_counters ?
struct xfrm_lifetime_cur { __u64 bytes; __u64 packets; __u64 add_time; __u64 use_time; }; Thanks Guangming zhangguangm...@baicells.com
