Are there any Cisco routers that support RMON?

Full RMON packet analysis (as described in RFC 1757) is supported only on an Ethernet interface of Cisco 2500 series routers and Cisco AS5200 series universal access servers. A generic RMON console application is recommended in order to take advantage of the RMON network management capabilities.

How does the RMON alarm group work in Cisco?

The RMON Alarm group periodically takes statistical samples from variables in a probe and compares them with previously configured thresholds. If the monitored variable crosses a threshold, an event is generated. The RMON Alarm group provides information on the alarm type, the interval, and the start and stop thresholds.
