Fix Recommendation

Configure the Cisco router to send the configuration to an TFTP or FTP server when a configuration change occurs as shown in the example below.

R4(config)#event manager applet BACKUP_CONFIG
R4(config-applet)#event syslog pattern "%SYS-5-CONFIG_I"
R4(config-applet)#action 1 cli command "enable"
R4(config-applet)#action 2 info type routername
R4(config-applet)#action 3 cli command "copy run tftp" pattern "remote host"
R4(config-applet)#action 4 cli command "x.x.x.x" pattern "filename"
R4(config-applet)#action 5 cli command "$_info_routername-config"
R4(config-applet)#action 6 syslog priority informational msg "Configuration backup was executed"
R4(config-applet)#end

Review the Cisco router configuration to verify that it is compliant with this requirement. The example configuration below will send the configuration to a TFTP server when a configuration change occurs.

event manager applet BACKUP_CONFIG
event syslog pattern "%SYS-5-CONFIG_I"
action 1 info type routername
action 2 cli command "enable"
action 3 cli command "copy run tftp" pattern "remote host"
action 4 cli command "x.x.x.x" pattern "filename"
action 5 cli command "$_info_routername-config"
action 6 syslog priority informational msg "Configuration backup was executed"

If the Cisco router is not configured to conduct backups of the configuration when changes occur, this is a finding.
