SNMP monitoring

Starting from the version 3.3, LANState supports SNMP monitoring. You are able to configure SNMP monitoring checks.

During SNMP check, the program monitors changes of parameters of active network equipment (routers, access points, printers, etc.) via SNMP protocol. Specify SNMP agent's address, community string, OID, value type, and the necessary value or substring to be checked. If detected values are equal to the specified values or contain the specified substring, the check is accepted as passed. For example, you can monitor router's capacity and rise alerts on traffic overload. Those may include: displaying a predefined message, playing a sound file, running external programs and commands with parameters, placing a record to log, sending an e-mail message.

Starting from the version 3.9, LANState supports switch port monitoring.

All hosts connected to a switch are registered in it in a special MAC address table and in a port table. These tables set the correspondence between physical addresses (MAC) of the hosts and ports of the switch. This monitoring check allows to promptly respond to changes in this data related to the selected host. To ensure the successful scanning, define the list of IP addresses of all switches in the network, their Community (data access password) and original values of port parameters and IP addresses of the switch, in which the host is to be registered. The scanning routine periodically retrieves host registration data from the switch and compares it to the original parameters. If the host, for example, is found on a different switch or on a different port, the program will notify you of that.
