Performance measurements

The test setup consisted of IEDs and a switch in a ring, and UDP multicast frames were sent at 5 ms
interval to measure the single link failure recovery time.

Reset to factory defaults

If a reset to factory default is performed on an IED with RSTP, then the IED will be reverted to the
factory settings with default values and RSTP will be disabled.

The recovery time of a link failure on RSTP with the IEDs that are using Galvanic
ports is higher than the IEDs with the Optical ports.
