What is the AnyConnect Reconnect (Connection Persistense) Behavior?
A. AnyConnect will attempt to reconnect if the connection is disrupted. This is not configurable at the moment, but automatic (see CSCsl52873). As long as the session on the ASA is still valid, if AnyConnect can re-establish the physical connection, the session will be resumed. The amount if time the AnyConnect will try to reconnect is stored in the client in a parameter called “Disconnect Timeout” and is by default set to the lowest of either the group-policy’s Idle Timeout or Maximum Connect Time. The enhancement request CSCsl52873, asks for the ASA platform to implement “Disconnect Timeout” as parameter in the Dynamic Access Policy and or group-policy. For customers who do not want the reconnect feature, can set the the group-policy’s Idle Timeout to a low value to prevent sleep or resume reconnects.
