5.2.6 arc
Use this command to configure ARC (Automatic Ring Configuration).
ARC supports MRP.
The ARC protocol is a simple protocol that checks a ring configuration and,
if suitable, configures all clients of this ring automatically.
The check cycle includes an analysis of the ARC devices for an already
active ring configuration and wrong ring configuration values. The ARC
devices can detect loop situations and other ARC Managers in the ring.
Errors are reported to the ARC Manager. With this information the ARC Man-
ager can decide whether a configuration of the ring clients is possible or not.
