Fix Recommendation

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

SW4(config)# event manager applet BACKUP_CONFIG
SW4(config-applet)# event syslog pattern "SYSLOG_CONFIG_I"
SW4(config-applet)# action 1 cli command "copy startup-config tftp://10.1.48.10/nx-config vrf default”
SW4(config-applet)# action 2 syslog priority informational msg "Configuration backup was executed"
SW4(config-applet)# end

Review the Cisco switch 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 "SYSLOG_CONFIG_I"
action 1 cli command "copy startup-config tftp://10.1.48.10/nx-config vrf default"
action 2 syslog priority informational msg "Configuration backup was executed"

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