Some notes :<\/p>\n\n\n\n

    \n
  1. The above script works with Router and Switches also.<\/li>\n\n\n\n
  2. puts just output – you can remove that lines once the EEM Script working.<\/li>\n\n\n\n
  3. if you are using AAA make a note: – If your device uses AAA, you must ensure that the EEM scripts configured on the device are either configured with an AAA user able to run the commands in the script, or that authorization bypass is configured with the command authorization bypass<\/strong> in the script definition. ( example – event manager applet DAILY_RUN_CONFIG_BACKUP<\/strong> authorization bypass<\/strong>)<\/li>\n<\/ol>\n\n\n\n

    Some good references updated on cisco IOS XE :<\/p>\n\n\n\n

    https:\/\/www.cisco.com\/c\/en\/us\/support\/docs\/ios-nx-os-software\/ios-xe-16\/216091-best-practices-and-useful-scripts-for-ee.html<\/a><\/p>\n\n\n\n

    <\/p>\n\n\n\n

    If you see any Error in IOS XE as below :<\/p>\n\n\n\n

    %HA_EM-3-FMPD_UNKNOWN_ENV: fh_parse_var: could not find environment variable: XXX<\/strong><\/p>\n\n\n\n

    This indicates that you have AAA configured and you need to add “authorization bypass”<\/strong><\/p>\n\n\n\n

    <\/p>\n\n\n\n

    event timer watchdog time 400<\/strong> – this is watch dog in seconds – so it run every 400 Seconds<\/p>\n\n\n\n

    You can also run using Cron example :<\/p>\n\n\n\n

    event timer cron name Daily cron-entry “00 01 * * *”<\/strong> – this run every day at 1:00am (https:\/\/crontab.guru\/ – give you good example)<\/p>\n\n\n\n

    <\/p>\n\n\n\n

    If you like to run EEM applet to test it :<\/p>\n\n\n\n

    #event manager run Mybackup<\/strong><\/p>\n\n\n\n

    <\/p>\n\n\n\n

    If you like to send email backup success :<\/strong><\/p>\n\n\n\n

    <\/h4>\n\n\n\n

    event manager environment _email_to email-address<\/p>\n\n\n\n

    event manager environment smtp.bb.com<\/p>\n\n\n\n

    event manager environment senderemail<\/p>\n\n\n\n

    (config)#event manager applet backup_success_email
    (config-applet)#event syslog pattern “%HA_EM-6-LOG: Mybackup: Configuration change detected. Write to TFTP succesfully executed”
    (config-applet)#action 1.0 mail server “$_email_server” to “$_email_to” from “$_email_from” subject “$_event_pub_time: Login via SSH” body “$_syslog_msg”
    (config-applet)#action 1.5 syslog msg priority 5 “LOGIN SUCCESS – Mail Sent”<\/p>\n\n\n\n

    <\/h1>\n\n\n\n

    Same way you can redirect the Logs to TFTP :<\/strong><\/p>\n\n\n\n

    event manager applet MyLog authorization bypass
    event none
    action 1.0 cli command “enable”
    action 2.0 info type routername
    action 3.0 cli command “show clock”
    action 3.1 regexp “(2[0-3]|[01][0-9]):([0-6][0-9]):([0-6][0-9])” “$_cli_result” time hour minute second
    action 3.6 cli command “show clock”
    action 3.7 regexp “(Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct|Nov|Dec) ([1-9]|0[1-9]|[1-2][0-9]|3[0-1]) (20[1-9][0-9])” “$_cli_result” time2 month day year
    action 4.0 cli command “show logging | redirect tftp:\/\/x.x.x.x\/$_info_routername-$year$month$day-$hour$minute$second.log”
    action 6.0 syslog priority informational msg “Configuration change detected. Write to TFTP succesfully executed”<\/p>\n\n\n\n

    <\/p>\n\n\n\n

    EEM Script to capture from log and store in Flash :<\/strong><\/p>\n\n\n\n

    <\/p>\n\n\n\n

    event manager applet logtest authorization bypass
    event none
    action 1.0 cli command “enable”
    action 1.1 set cmd01 “show logging | in BULK”
    action 1.2 cli command “$cmd01”
    action 1.3 file open fh flash:error.txt w
    action 1.4 file write fh “$_cli_result”
    action 1.5 file close fh<\/p>\n\n\n\n

    #event manager run logtest<\/strong><\/p>\n\n\n\n

    #more flash:error.txt<\/strong><\/p>\n\n\n\n
