This read-write action flag lets an administrator manually trigger rerouting of a connection by setting it to true, while setting it to false performs no action and a read of the object always returns false regardless of what was last written - making it a fire-once trigger rather than a persistent state. Admins use this to force a connection onto a potentially better path (for example, after a preferred trunk has come back into service), and the description notes this capability isn't available on MGX Release 1.x systems. For example, after a previously failed high-bandwidth trunk is restored, an admin might set ausmChanReroute to true to prompt the connection to migrate off its current suboptimal backup path back onto the restored trunk.
