20.2.9 Threshold-checking of specified MIB by RMON

Points to note

Configure a switch to be used to regularly check the threshold value for a specific MIB value, and to notify the SNMP manager of an event if the threshold value is exceeded.

If you specify trap as an event execution method, you must configure the SNMP trap mode beforehand.

Command examples

1. (config)# rmon event 3 log trap public

   Configures an event to be executed when an alarm is generated.

   • Information identification number: 3

   • Event execution method: log or trap

   • SNMP notification destination community name:public

2. (config)# rmon alarm 12 "ifOutDiscards.3" 256111 delta rising-threshold 400000 rising-event-index 3 falling-threshold 100 falling-event-index 3 owner "NET-MANAGER"

   Configures control information for the RMON alarm group for the following conditions:

   • Control information identification number for the RMON alarm group: 12

   • Object identifier for the MIB used for checking the threshold: ifOutDiscards.3

   • Time interval for checking the threshold: 256111 seconds

   • Method for checking the threshold: difference value check (delta)

   • Upper threshold value: 400000

   • Identification number of the method for generating an event if the upper threshold is exceeded: 3

   • Lower threshold value: 100

   • Identification number of the method for generating an event if the lower threshold is exceeded: 3

   • Identification information for the person responsible for configuration: NET-MANAGER
