The fast convergence mode allows EAPS to converge more rapidly. In EAPS fast convergence mode, the link filters on EAPS ring ports are turned off. In this case, an instant notification is sent to the EAPS process if a port‘s state transitions from up to down or vice-versa.
You must configure fast convergence for the entire switch, not by EAPS domain.
For optimum performance and convergence, it is recommended to use fiber cables.
