Default Rmon Configuration; Configuring Rmon Alarms And Events - Cisco WS-C3550-12G Software Configuration Manual

Chapter 16 Configuring RMON

Default RMON Configuration

RMON is disabled by default; no alarms or events are configured.
Only RMON 1 is supported on the switch.

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 RMON's network
management capabilities. You must also configure SNMP on the switch to access RMON MIB objects.

For number, specify the alarm number. The
range is 1 to 65535.
For variable, specify the MIB object to
monitor.
For interval, specify the time in seconds the
alarm monitors the MIB variable. The range is
1 to 4294967295 seconds.
Specify the delta keyword to test the change
between samples of a MIB variable; specify the
absolute keyword to test each MIB variable
directly.
For value, specify a number at which the alarm
is triggered and one for when the alarm is reset.
The range for the rising threshold and falling
threshold values is -2147483648 to
2147483647.
(Optional) For event-number, specify the event
number to trigger when the rising or falling
threshold exceeds its limit.
(Optional) For string, specify the owner of the
alarm.
