</font></div><div class="MsoNormal" style="margin: 0in 0in 10pt;"><span style='line-height: 115%; font-family: "Comic Sans MS"; font-size: 10pt;'>I set the “/proc/sys/net/core/xfrm_acq_expires” to 23000
seconds. I tested with 15k IPsec tunnels successfully without encountering any
issue. While trying to run with 20000 IPsec tunnels without data traffic, it
could able to bring up 19939 tunnels. Checked the SAD count via ip xfrm state
count. Also the IPsec Tunnel Setup was very low.<span style="mso-spacerun: yes;"> </span>To bring these 19939 tunnels, it takes 6
hours (approximately). We are using the Gigabit Ethernet link between two high
end systems (One acts as an IKE initiator and another as IKE responder) I cannot
enable logging with 20k IPsec tunnels to debug this issue. Can anyone please
suggest/guide, what are the areas to be looked upon? So that I can scale up with
more numbers of tunnels.<span style="mso-spacerun: yes;"> Thanks in advance for your help.</span></span></div><div class="MsoNormal" style="margin: 0in 0in 10pt;"><span style='line-height: 115%; font-family: "Comic Sans MS"; font-size: 10pt;'><span style="mso-spacerun: yes;"></span></span> </div><div class="MsoNormal" style="margin: 0in 0in 10pt;"><span style='line-height: 115%; font-family: "Comic Sans MS"; font-size: 10pt;'><span style="mso-spacerun: yes;"></span>Here go our
