Default RMON Configuration
RMON is disabled by default; no alarms or events are configured.
Configuring RMON Alarms and Events
You can configure your switch for RMON by using the command-line interface (CLI) or an
SNMP-compatible network management station. We recommend that you use a generic RMON console
application on the network management station (NMS) to take advantage of the RMON network
management capabilities. You must also configure SNMP on the switch to access RMON MIB objects.
For more information, see
64-bit counters are not supported for RMON alarms.
Note
Beginning in privileged EXEC mode, follow these steps to enable RMON alarms and events. This
procedure is required.
