Network Switch Configuration

Network Switch Configuration

This section provides an example configuration of a network switch. We will use a CISCO SG300 series  switch to
demonstrate the procedures and options. This is a managed network switch that allows  remote configuration from
a browser-based interface. Note that the CISCO switches are non-PTP aware, and therefore you should also refer
to the 

Arista 7150S

 topic for an example of the PTP-aware switch options.

If you are using a different  manufacturer's  switch,  then the user interface and its  terminology  may  differ.  Please
refer to the switch documentation to help locate (and configure) the equivalent options.

You should configure the network switch first, before connecting the RAVENNA-enabled devices.

Note  that  our  example  configures  the  switch  for  a  single  vLAN  (virtual  Local  Area  Network).  However,  if  the
network is large or the switch is  to be used for other devices  (Control System,  Service ports,  company  network,
etc.), then it is  a good idea to divide the network  traffic  by  creating separate vLANs.  This  will avoid unnecessary
packet transfers between different types of device and make the network more stable.  Please refer to your switch
documentation for more details.

All RAVENNA streaming interfaces must connect to the same vLAN.
