ask customer about topology and some commands outputs as below:
![]()
• Run the display ipsec sa [ brief | duration | policy policy-name [ seq-number ] | profile profile-name |peerip peer-ip-address ] command to check IPSec SA information.
• Run the display ipsec policy [ brief | name policy-name [seq-number ] ] command to check IPSec policy information.
• Run the display ipsec statistics { ah | esp } command to check statistics on IPSec packets.
• Run the display ike statistics { all | msg | v1 | v2 } command to check statistics on IKE packets.
#display ike sa
#display ip routing-table
#dis ACL

the result is:
