802.1AS Timesync Commands
Dell Networking N4000 Series Switches
This section covers commands related to IEEE 802.1AS timesync. The Dell
Networking 802.1AS capability implements the 2008 PTP Version 2 of the
IEEE 1588 protocol in support of Audio-Visual Bridging. Dell Networking
802.1AS implements the best master clock algorithm to select a precise time
source and to measure propagation delay accurately. Dell Networking
switches are not Grand Master clock capable. A Grand Master clock time
source must be supplied for a precise measurement of propagation delay.
