Chapter 2 - Managed Switch Quick Start
Better Network ‘Awareness’:
The ability of the process to know when something is wrong with the network and what
is wrong with the network is a great feature of the Stride managed switches. Your PLC or
controlling device can make ‘smarter’ decisions as to what alarms or fallback behavior to
trigger based upon the different diagnostic data that is supplied by the switch.
• Modbus Stats: If you have a controlling device on the network that has Modbus TCP or UDP
client capability, there are several diagnostic tags that can be read from the switch to indicate the
health of the network.
• SNMP: SNMP stands for Simple Network Management Protocol and is used for just that. There
are many software tools out there that can query or receive ‘traps’ sent by the Stride managed switch
to ascertain events or health of the switch.
• Port and Power Status (Alarm Output):
The Stride managed switch has two power inputs that
can be used for redundancy. If one of the power inputs fails, there is a relay contact that can be
configured to report this failure.
• Spanning Tree Status: The switch can be configured to report when something in the Spanning
Tree has changed.
• Real-Time Ring Status: The Real-Time Ring status can be ascertained from other devices as well.
• MAC Table: The switch keeps a table of the MAC IDs of devices that are communicating on it
