What isRMON

RMON (Remote Monitoring) is a protocol that extends the Simple Network Management Protocol (SNMP) and enhances the Management Information Base (MIB) structure. It was introduced in 1991 to enhance the network monitoring capabilities of SNMP. By querying the standard MIB of a network device, RMON can provide network administrators with valuable insights into network performance.

RMON enables alarms on various traffic situations, including errors, and takes proactive measures to improve network performance. It only inspects layers 1 and 2 of the OSI model; however, RMON2 introduced a parallel set of MIBs that enables the inspection of layer 3 and higher network layers. The protocols and application traffic tracked depend on the RMON2 configuration. Since RMON capabilities are vast, only a portion of them is typically included in routers and other network devices.


What is RMON used for?

RMON is used for network monitoring and enhancing network performance. It enables network administrators to create alarms on specific traffic situations and take proactive measures to prevent issues.

What layers of the OSI model does RMON inspect?

RMON inspects layers 1 and 2 of the OSI model. RMON2, however, introduced a parallel set of MIBs that enables layer 3 and higher network layer inspection.

What are the benefits of RMON?

RMON benefits include enhanced network performance, increased network security, proactive monitoring, and alerts. It enables network administrators to quickly identify and address potential network issues.

Final Thoughts

RMON is an essential protocol for network administrators who need to monitor and improve network performance. By extending the capabilities of SNMP, RMON has become a powerful tool for enhancing network security and addressing potential network issues proactively.
