Fix Recommendation

Disable configuration auto-loading if enabled using the following commands:

SW1(config)#no boot network
SW1(config)#no service config

Disable CNS zero-touch deployment if enabled as shown in the example below:

SW2(config)#no cns config initial
SW2(config)#no cns exec
SW2(config)#no cns image
SW2(config)#no cns trusted-server config x.x.x.x
SW2(config)#no cns trusted-server image x.x.x.x

Check Contents

Review the device configuration to determine if auto-configuration or zero-touch deployment via Cisco Networking Services (CNS) is enabled.

Auto-configuration example:

version 15.0
service config
…
…
…
boot-start-marker
boot network tftp://x.x.x.x/R5-config
boot-end-marker

CNS Zero-Touch example:

cns trusted-server config x.x.x.x
cns trusted-server image x.x.x.x
cns config initial x.x.x.x 80
cns exec 80
cns image

If a configuration auto-loading feature or zero-touch deployment feature is enabled, this is a finding.

Note: Auto-configuration or zero-touch deployment features can be enabled when the switch is offline for the purpose of image loading or building out the configuration. In addition, this would not be applicable to the provisioning of virtual switches via a software-defined network (SDN) orchestration system.
