Enabling RMON on the Switch
The embedded RMON agent allows the switch to monitor network traffic from all ports simultaneously
at Layer 2 without requiring a dedicated monitoring probe or network analyzer. For more information

Viewing the RMON Data
Access to the RMON data is available only on a network management system (NMS) that supports
RFC 1757 and RFC 2021 (see the “Using CiscoWorks2000” section on page 47-6). You cannot access
the RMON data through the switch CLI; however, the CLI show commands provide similar information.
