Configuring Embedded Event Manager
This example shows the output for EEM when one of the fields specified by an SNMP object ID crosses
a defined threshold:
a defined threshold:
Switch(config-applet)# event snmp oid 1.3.6.1.4.1.9.9.48.1.1.1.6.1 get-type exact entry-op
lt entry-val 5120000 poll-interval 10
These examples show actions that are taken in response to an EEM event:
Switch(config-applet)# action 1.0 syslog priority critical msg "Memory exhausted; current
available memory is $_snmp_oid_val bytes"
Switch (config-applet)# action 2.0 force-switchover
Registering and Defining an Embedded Event Manager TCL Script
Beginning in privileged EXEC mode, perform this task to register a TCL script with EEM and to define
the TCL script and policy commands.
the TCL script and policy commands.
This example shows the sample output for the show event manager environment command:
Switch# show event manager environment all
No. Name Value
1 _cron_entry 0-59/2 0-23/1 * * 0-6
2 _show_cmd show ver
3 _syslog_pattern .*UPDOWN.*Ethernet1/0.*

Specify the action when an EEM applet is triggered. Repeat this action to
add other CLI commands to the applet.
