EEM script issue while Backup on copy running-config startup-config

[vishalsahu]

Hello

I working an organisation. There I am using EEM script to take backup when any user put copy running-config startup-config command in Nexus switch. But I am getting error % command blocked by event manager policy. Below is the script for reference

event manager applet BACKUP_CONFIG

 Event cli match "copy running-config startup-config"

 action 1.0 cli command "copy running-config tftp://tftp-server/backup_config.txt"

action 2.0 syslog msg Backup copied successfully

Kindly help here

In Nexus 9k  switch there is no that kind of command. Above mentioned cmd only there have. Can you suggest me how to bypass error with policy default. Earlier i read somewhere but I misplaced the post.

Hi 

Already tried, But there i cannot override it. Might be Some argument have to pass on it

event manager applet applet-name override system-policy 
here you need to know if you apply system-policy and it name 
did you check you all config about the system-policy ?

I think this statement answer your Q

• If you want to allow a triggered event to process any default actions, you must configure the EEM policy to allow the default action. For example, if you match a CLI command in a match statement, you must add the event-default action statement to the EEM policy or EEM will not allow the CLI command to execute.

In some Cisco Nexus N9K-NXOS-Releases, there is a workaround needed to execute "critical" commands.

* usually it works in EEM-Applets to

a) "source out" the original command to a "cli alias" and

b) call that "alias" from the applet

similar to that:  

conf t
  cli alias name wrbak copy running-config tftp://tftp-server/backup_config.txt

  event manager applet  BACKUP_CONFIG
    no action 1.0
    action 1.0 cli command "wrbak"

end

Hello

I tried but nothing works. But I have remembered somewhere i find the solution for this by adding policy default cmd but I missed that post

to event ?

[vishalsahu]

Yes.

[MHM Cisco World]

event manager applet FTPBackup

 event cli match "copy running-config startup-config"

 action 0.3 syslog msg "Backup started."

 action 0.5 cli command "enable" 

 action 1.0 cli command "copy running-config ftp://user:password@ourserver.com/path/$(SWITCHNAME)_$(TIMESTAMP) vrf default" 

 action 1.6 syslog msg "Backup ended."

 action 2.0 event-default

I know - not what you might want, but would work out of the box:

* CLI-Alias with 2x commands instead of EEM:

cli alias name wr copy running-config startup-config ; copy running-config ftp://***FTPUSERNAME***:***FTPPASSWORD***@***FTPSERVERIP***/$(SWITCHNAME)-conf.$(TIMESTAMP) vrf default
