Fix Information

BIG-IP will stop accepting new TCP connections if it detects a topology change during a configurable timeout (l2.virtualwire.tcn.recovery.connection.drop.timeout, default 30). This feature is not enabled by default. To enable l2.virtualwire.tcn.connection.drop this variable needs to be set.
