What impact is caused when disabling CDP and LLDP on ONTAP?

Last Updated:

Applies to

  • ONTAP 9
  • Cisco Discovery Protocol (CDP)
  • Link Layer Discovery Protocol (LLDP)


  • Disabling these protocols prevents ONTAP from detecting the neighbor information.
  • The cluster network and switchless configuration detection use these protocols to view the information of neighboring devices that are connected to each port of the nodes.

Additional Information

In order to add a switch when CDP and LLDP are disabled, use system cluster-switch create command
