The internal Ethernet switch can be configured to act as a 1588 "boundary clock" implementing the IEEE 1588 delay request-response default PTP profile (sometimes referred to as "default profile"). When so configured, it can synchronize local measurement signals to other devices across an IP subnetwork and can serve as a bridge, synchronizing 1588 devices that are attached to each of the two ports. Refer to Synchronization across a Network for more details.
