Dear Forum Community!
We have a Cisco 3020 concentrator VPN load-balancing cluster configured, the device at primary site operating with master priority. We would like to shut down the master device because of a short maintenance.
I wonder if there is an option in VPN concentrator GUI, which waits for all active sessions to voluntary terminate before shutdown/reboot. Does anybody have any experience about this feature?
There are always ~80-100 remote access VPN user online, and don't want to break these user's connections with a simple poweroff.
Thanks and BR
I just wanted to clarify two things.
I always save my configuration file ahead of rebooting. That is why I reboot without saving. I think my wording may have been misleading.
If you require your clients to re-authenticate the VPN session after a specified period of time, for example 10 hours, the VPN session will be moved to another cluster member when the session is re-authenticated. Each client won't have to re-establish the VPN session on another concentrator in the cluster. If you are not using this feature you'll have to wait until each of them terminates his VPN session.
