RMON

Using the Remote Monitoring (RMON) capabilities of the switch allows network 
administrators to improve switch efficiency and reduce the load on the network.

The following sections explain more about the RMON concept and the RMON features 
supported by the Summit.

You can only use the RMON features of the switch if you have an RMON 
management application.

RMON is the common abbreviation for the Remote Monitoring Management 
Information Base (MIB) system defined by the Internet Engineering Task Force (IETF) 
documents RFC 1271 and RFC 1757, which allows you to monitor LANs remotely.
