The Simple Network Management Protocol SNMP is an application level protocol developed for the Internet suite of protocols. It is a connectionless protocol that provides a basic, easily implemented network-management tool for TCP/IP-based environments. With the current Internet management information base standard for SNMP (MIB-II) a network manager can obtain information that is local to a managed device. However, a manager cannot easily learn about traffic as a whole on the LAN.A valuable addition to SNMP, which provides the network manager with important global network information, is the remote network monitoring (RMON) standard. RMON agents, unlike SNMP agents, operate in promiscuous mode and process all packets occurring on the net. The RMON MIB supplements MIB II.This paper presents common network problems that cannot be solved using existing MIB-II or RMON objects. To solve these problems we recommend new MIB objects that extend the RMON matrix group to provide network layer statistics which give a view of packet traffic beyond the local network. We show that network configuration and troubleshooting are improved and verify our results by example.
