The parameters
– Forward Delay and
– Max Age
have the following relationship to each other:
Forward Delay >= (Max Age/2) + 1
If you enter values that contradict this relationship, the device then replaces
these values with a default value or with the last valid values.
Time since
last change This field displays the time that has
elapsed since the last network reconfigu-
ration.
Information This frame shows if there is a configuration
conflict.
In this case, a device exists outside the
MRP ring with the given MAC address.
This device's displayed priority is better
(numerically lower) than the root bridge's
priority inside the MRP ring.
To resolve the conflict, set the the dis-
played device's priority to a worse value
(numerically higher) than root bridge's
priority inside the MRP ring.
