Configuring RMON and RMON2

RMON (Remote MONitoring) and RMON2 provide remote troubleshooting and monitoring

within a LAN segment and across an enterprise network.

• RMON provides statistics at the media access control (MAC) layer, allowing you to capture

real-time information across the entire network.

• RMON2 extends the scope of RMON beyond the MAC layer to provide statistics on network

and application layer traffic (layers 3 through 7 of the OSI model). By monitoring higher-layer

protocols, you can obtain an internetwork or enterprise-wide view of network traffic.

This manual describes how to configure RMON and RMON2 services on a Nortel Networks

router.

Event Messages Database

The event messages database contains a description of all the messages that appear in BayRS

router event logs, except for Debug events. If you monitor the log file and see a message that you

do not understand, use the event code to query the event database for a description and a course of

action. Third-party network management software can also use the event code to retrieve

information from the database.
