2.3.2 DR (Dynamic Reconfiguration) linkage

It is possible to use a DR (Dynamic Reconfiguration) function ("a DR function") provided by PRIMEPOWER 800/900/1000/1500/2000/2500 and GP7000F M1000/2000.

A DR connection script is provided to realize DR in a Redundant Line Control function. Therefore, a DR connection script is invoked by executing a DR command, and it disconnects or connects a virtual interface (sha0, etc.) and an actual interface (hme0, etc.). This makes it possible to execute a DR function without realizing an interface, a function, and a DR connection script used in various modes. "Figure 2.46 The outline of the workings of DR" shows a flow of exchanging system boards (SB) using a DR function.
