Configuring RMON

The Remote Network Monitoring (RMON) MIB is an interface between the RMON agent on the Passport 1424T switch and an RMON management application, such as the Device Manager. It defines objects that are suitable for the management of any type of network, but some groups are targeted for Ethernet networks in particular. Enabling RMON on the switch allows the RMON agent to continuously collect statistics and proactively monitor switch performance. This data can then be viewed using Device Manager.

RMON has three major functions:

• Gathering cumulative statistics for Ethernet interfaces
• Tracking a history of statistics for Ethernet interfaces
• Creating and displaying alarms for user-defined events



Note: Before using RMON functions, you must globally enable RMON. In addition, you should specify certain options to control how RMON operates on the switch.

• Configuring and enabling RMON options
• Using Ethernet statistics
• Understanding RMON history
• Graphing RMON history
• Configuring RMON alarms
