Managed Switch:
With a controlled switch, the integrated network can communicate, giving you more control over LAN traffic management and more importantly.
It checks the data that passes through the network and saves access to the data through a protocol such as SNMP (Network Router Network), which checks all devices connected to the network.
With SNMP, the network can modify information and monitor activities to identify network activities, problems, and more.
Guided navigation with SNMP improves network performance through easy-to-understand graphical mapping, analysis, and processing.
