The max age timer should be set to 22 when RSTP is used for cable redundancy to
prevent a defective cable or powering switch from influencing the system.
Each time data hops from one switch to another, the age is increased by one. This timer
can be reached or exceeded, because a daisy chain can be used to loop through the
DICENTIS devices.
This timer (or restriction) cannot be reached when there is no cable redundancy. This is
because the power limitation will be reached before the max age restriction is reached.
The timer can be reached when:
– you use cable redundancy,
– the system is incorrectly wired.
