There seems to be a lot of information about other Cisco VPN technologies (ASA/Firepower/Anyconnect) but I am not finding much relating to FlexVPN (site-to-site) tunnels. Maybe I am not looking up the correct terminology. FlexVPN runs on IOS XE.
I have logging configured the same as far as using logging trap informational (default) and noticed that we seem to not be getting a lot of data relating to the specifics with the tunnels, negotiations, etc., from a raw syslog perspective.
What we would like to be able to do is monitor the tunnels so whenever a tunnel is brought up, taken down, or source (connection) IPs change. Possibly other things we haven't though of yet, hoping to encounter someone else who has used the same technologies and has something already built out.
Thank you in advance.
Honestly kind of surprised here especially with the recent Cisco acquisition since this is using a Cisco technology. I feel like there would be more input on how we can do this.
No ideas?
