If you are running a newer version in your Cisco ASA then you may not realize that that “crypto isakmp policy” command is gone or deprecated
In my case I am running 9.6 and the command was removed in 8.4 and above versions
The new command is “crypto ikev1 policy” which replaces the cypto isakmp policy” command in all Cisco ASA’s that are running the version higher than 8.4 .
Quick fix for the guys who have been using the older code and once you upgrade and need to setup an ipsec tunnel then you see the missing command 🙂
Thanks for the reading this and let me know if this is not accurate.
