Note To configure any type of RMON alarm (absolute or delta, rising or falling threshold) click More on the
Threshold Manager dialog box. You should be familiar with how RMON defines these concepts before
configuring these advanced alarm types. Refer to the RMON-MIB (RFC 2819) for information on how
to configure RMON alarms.
You must also configure SNMP on the switch to access RMON MIB objects.
Note

RMON Alarm Configuration

Threshold Manager provides a list of common MIB objects that you may want to set an RMON threshold
and alarm on. You can also set an alarm on any MIB object. The specified MIB must be an existing
SNMP MIB object in standard dot notation (1.3.6.1.2.1.2.2.1.14.16 for ifInOctets.16).
Use one of the following options to specify the interval to monitor the MIB variable (ranges from 1 to
4294967295 seconds):
•
•
•
The range for the rising threshold and falling threshold values is -2147483647 to 2147483647.
The falling threshold must be less than the rising threshold.
Caution
You can optionally specify the following parameters:

Enabling RMON Alarms by Port

To configure an RMON alarm for one or more ports using Device Manager, follow these steps:
Choose Admin > Events > Threshold Manager and click the FC Interfaces tab.
Step 1
You see the Threshold Manager dialog box shown in
Cisco MDS 9000 Family CLI Configuration Guide
61-2
Value—The value of the variable that you want the alarm to trigger at. This value is the difference
(delta) between two consecutive polls of the variable by Device Manager.
Sample—The sample period (in seconds) between two consecutive polls of the variable. Select your
sample period such that the variable would not cross the threshold value you set under normal
operating conditions.
Warning—The warning level used by Device Manager to indicate the severity of the triggered alarm.
This is a Fabric Manager and Device Manager enhancement to RMON.
Use the delta option to test the change between samples of a MIB variable.
Use the absolute option to test each MIB variable directly.
Use the delta option to test any MIB objects that are counters.
The event-number to trigger if the rising or falling threshold exceeds the specified limit.
The owner of the alarm.
