intermittenly we are seeing tunnel go down between HUB and satellite office and getting notification.
GlobalProtect Site to Site Gateway tunnel monitor down.Tunnel monitoring failed on tunnel interface:tunnelXXX to Satellite XXXX due to: Satellite not available
any help with troubleshooting steps would be helpful.
Check the following CLI output:
> show global-protect-satellite current-gateway
It will tell details of tunnel like:
Tunnel Monitor Enabled : Yes
Tunnel Monitor Interval : 3 seconds
Tunnel Monitor Action : fail-over
Tunnel Monitor Threshold : 5 attempts
Tunnel Monitor Source : 10.11.12.12
Tunnel Monitor Destination : 172.16.1.254
Tunnel Monitor Status : Up
Make sure you have proper connectivity between the above source and destination, also if there are any route flaps as you mentioned it is intermittent.
