Disabling DCBX Application Protocol Exchange on EX Series Switches (CLI Procedure)

 

You can disable the Data Center Bridging Capability Exchange protocol (DCBX) Application Protocol exchange on a specific interface or on all interfaces.

To disable the DCBX application protocol exchange for any DCBX application, do the following:

Note

The format of the configuration statement specifies the fcoe application, however, this applies to any DCBX application (both FCoE applications and non-FCoE applications) on that interface.

  • For a specific interface:

    [edit protocols]

    user@switch# set dcbx interface interface-name applications fcoe no-auto-negotiation
  • For all interfaces:

    [edit protocols]

    user@switch# set dcbx interface all applications fcoe no-auto-negotiation
Note

If you disable the DCBX application protocol exchange, the show dcbx neighbors command displays Feature: Application, Protocol-State: not-applicable.
