Reboot delay of remote shelf on lost connection

[pcx-amateur]

Hi everybody,

we have a remote site, that is connected via VPN tunnel which can failover between two internet circuits.
The failover takes a few seconds (about 3 lost pings) but the GD3 seems to reboot almost instantly when the connection to the main site fails.
It comes back up fine, but it does take some time so ideally I would like to avoid the reboot.

Is there anything like a timer that says "when the connection is lost, wait x seconds before reboot"?

We are using Omnivista 8770 for configuration.

Thank you.

Sebastian
