External Switch Requirements

    Last Modified: March 12, 2018

    To meet the minimum requirements for successful operation with FieldDAQ devices, any switch directly connected to the FieldDAQ device should be compliant with IEEE 802.1Q-1998 bridges and bridged networks.

    To take advantage of the network synchronization and network redundancy features of the FieldDAQ device, ensure that your network infrastructure meets certain requirements:

    • IEEE 802.1AS-2011 time-based synchronization support—Automatically synchronizes timebases and enables the use of time-based triggers and multi-device tasks between device across the network.
    • IEEE 802.1Q-2014 (Rapid Spanning Tree Protocol) support—Supports network redundancy functionality in ring and star topologies
      • Rapid Spanning Tree Protocol (RSTP) enabled
      • Bridge Protocol Data Units (BPDU) Guard disabled
