SWITCHING
ERPS can also be used to increase the availability and robustness of
Ethernet rings, such as those used in Metropolitan Area Networks (MAN).
ERPS technology converges in a little over 50 ms. ERPS supports up to 255
nodes in the ring structure. And the convergence time is also independent
of the number of nodes in the ring.
SYSTEM DEFAULTS
