EEM - Email the CLI output from router

This example shows how to quickly send the logs and configuration to TAC easily with EEM.

1. Configure the following required email related EEM environment variables:
event manager environment _email_server 1.2.3.4
event manager environment _email_from panda@pandaeatsbamboo.com
event manager environment _email_to attach@cisco.com

2. Configure the following EEM Applet named “sendtech”:
event manager applet sendtech
event none
action 1.1 cli command "enable"
action 1.2 cli command "del /force flash:show_tech"
action 1.3 cli command "show tech | append flash:show_tech"
action 1.4 cli command "show ip route | append flash:show_tech"
action 1.5 cli command "show ip interface brief | append flash:show_tech"
action 1.6 cli command "more flash:show_tech"
action 1.7 syslog msg "Sending show tech..."
action 1.8 mail server $_email_server to $_email_to from $_email_from subject " Show Tech Output (SR99999) " body "$_cli_result"
action 1.9 syslog msg "Show tech sent!"

Explanation of EEM Applet:
event manager applet sendtech ! registers applet with the name ‘sendtech’
event none
! specifies the event which will trigger this applet – in this case, the applet will be triggered manually


3. Verify that the EEM applet has been registered and that the environment variables have been set correctly:

R3#show event manager policy registered
