Dell S6000-ON, Configuration Manual

Page: 758 / 1080

The following example configures RMON alarm number 10. The alarm monitors the MIB variable
1.3.6.1.2.1.2.2.1.20.1 (ifEntry.ifOutErrors) once every 20 seconds until the alarm is disabled, and checks the
rise or fall of the variable. The alarm is triggered when the 1.3.6.1.2.1.2.2.1.20.1 value shows a MIB counter
increase of 15 or more (such as from 100000 to 100015). The alarm then triggers event number 1, which
is configured with the RMON event command. Possible events include a log entry or an SNMP trap. If the
1.3.6.1.2.1.2.2.1.20.1 value changes to 0 (falling-threshold 0), the alarm is reset and can be triggered again.

Configuring an RMON Event
To add an event in the RMON event table, use the
rmon event
command in GLOBAL CONFIGURATION
mode.
• Add an event in the RMON event table.
CONFIGURATION mode
[no] rmon event number [ log ] [trap community] [description string] [owner
string]
–
number
: assigned event number, which is identical to the eventIndex in the eventTable in the
RMON MIB. The value must be an integer from 1 to 65,535 and be unique in the RMON Event
Table.
–
log
: (Optional) generates an RMON log entry when the event is triggered and sets the eventType
in the RMON MIB to log or log-and-trap. Default is no log.
–
trap community
: (Optional) SNMP community string used for this trap. Configures the setting of
the eventType in the RMON MIB for this row as either snmp-trap snmptrap or log-and-trap. This
value is identical to the eventCommunityValue in the eventTable in the RMON MIB. Default is
public.
–
description string
: (Optional) specifies a description of the event, which is identical to the
event description in the eventTable of the RMON MIB. The default is a null-terminated string .
–
owner string
: (Optional) owner of this event, which is identical to the eventOwner in the
eventTable of the RMON MIB. Default is a null-terminated string .
Example of the
rmon event
Command
To disable RMON on the interface, use the
no
form of this command.
In the following example, the configuration creates RMON event number 1, with the description “High
ifOutErrors”, and generates a log entry when an alarm triggers the event. The user
nms1 owns the row
that is created in the event table by this command. This configuration also generates an SNMP trap when
the event is triggered using the SNMP community string “eventtrap”.
Dell(conf)#rmon event 1 log trap eventtrap description “High ifOutErrors” owner
