SNMP Monitoring

All LAN-RING switches meet the above-mentioned requirements of EN 62676-1-2 and therefore, among other things, allow detailed monitoring using the encrypted SNMPv3 protocol.

An older version of SNMPv2c is also available, but this is not secure and is recommended for security applications. All variables that can be read or set using SNMP protocols are divided into so-called MIB files. These are subdivided into PUBLIC and PRIVATE groups in a tree structure, see the figure on the right. The MIB files in the PUBLIC group are also available for switches from other manufacturers, while the PRIVATE MIB files are only available for LAN-RING switches and allow you to perform advanced tasks that are not available for other devices.

Typical examples of SNMP protocol usage include:

  • PoE power monitoring and control,
  • monitoring RS485 ports or the status of the optical ring,
  • controlling relays
  • sending SNMP traps when 802.1X authentication fails, power failure, and similar situations.

The system monitoring capabilities using SNMP are very extensive for LAN-RING protocol-enabled switches. This allows the system operator to get a detailed overview of the system's current status, performance, and potential problems. With full use of these monitoring functions, it is possible to effectively manage the network infrastructure, prevent outages and optimize its operation in real time.
