Configuring RMON
• Default RMON Configuration, page 23-3
• Configuring RMON Alarms and Events, page 23-3 (required)
• Collecting Group History Statistics on an Interface, page 23-5 (optional)
• Collecting Group Ethernet Statistics on an Interface, page 23-5 (optional)
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 Chapter 25, “Configuring SNMP.”
Note 64-bit counters are not supported for RMON alarms.
Beginning in privileged EXEC mode, follow these steps to enable RMON alarms and events. This
procedure is required.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
rmon alarm number variable interval {absolute
| delta} rising-threshold value [event-number]
falling-threshold value [event-number]
[owner string]
Set an alarm on a MIB object.
• 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 absolute keyword to test each MIB variable
directly. Specify the delta keyword to test the change
between samples of a MIB variable.
• 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 owner string, specify the owner of the alarm.
