In the GUI tunnel status is displayed under Network > IPSec Tunnels. 

The CLI is where I like to look at this simply because it gives you more information.

show vpn ike-sa gateway <gatway-name>

show vpn ipsec-sa tunnel <tunnel-name> 

 

When you setup an IPSec tunnel I would always recommend that you monitor the tunnel through IPs assigned to the tunnel interface or by monitoring an IP address local to the other side such as the firewall management IP itself. This will ensure that you are always alerted if the tunnel maybe doesn't actually go down, but stops properly passing traffic for whatever reason. 

Hi Bpry,

 

Appreciated  for your comments..& noted your suggestions!!

 

Actually the issue with  solarwinds reporting all the branch network devices were down at early morning around 5.25 am.

it is reported today also almost simlar time & suspect ipsec tunnel might gone down during this time. I noticed that dynamic updates scheduled to  install almost same time, but no conclusion & clues.

Hello,

Check the system logs around that time and filter by type VPN to see if there is a coorelation. Also check your polling interval in solarwinds. I also use it to monitor my VPN tunnels, but have it set to poll every 1 min that way I dont get alerts to minor things that were automatically corrected. Also check with the ISP to see if they have routing maintenance? I have seen weirder things in the past.

Hi All

Thanks
