Non-PTP Switches
The Spider system can work with any Ethernet switch, even if it is not PTP-
enabled however, synchronization will not be as accurate. With two Spider
modules, synchronization is within about 1 microsecond. Additional modules and
interference from external network traffic will significantly degrade this
performance.
For any Spider system, it is recommended to use a separate network that is not
shared with other hosts or services (i.e. separate from an office LAN). For
reliability and performance reasons external traffic not related to the data
acquisition should be eliminated as much as possible. Also, for any system with
more than two modules, only the Spider-HUB or the Cisco IE3000 should be
used.
The following chart lists the synchronization capabilities of different Ethernet
switch types:
