I tried Monitoring-->VPN Statistics--> Session--->Filtered By---> IPSec Site-to-site . Well, aside from traffic passing successfully through the new tunnels, the command: will show the status of the tunnels (command reference). Could you please list down the commands to verify the status and in-depth details of each command output ?. You might have to use a drop down menu in the actual VPN page to select Site to Site VPN / L2L VPN show you can list the L2L VPN connections possibly active on the ASA. Some of the command formats depend on your ASA software level. Refer to the Certificate to ISAKMP Profile Mapping section of the Internet Key Exchange for IPsec VPNs Configuration Guide, Cisco IOS XE Release 3S Cisco document for information about how to set this up. Here is an example: In order to create or modify a crypto map entry and enter the crypto map configuration mode, enter the crypto map global configuration command. If there are multiple VPN tunnels on the ASA, it is recommended to use conditional debugs (. Thus, you see 'PFS (Y/N): N, DH group: none' until the first rekey. Assigning the crypto map set to an interface instructs the ASA to evaluate all the traffic against the crypto map set and to use the specified policy during connection or SA negotiation.
