Applying an Application Map to an Interface for DCBX Application Protocol TLV Exchange

 

After you define applications and map them to IEEE 802.1p code points in an application map, apply the application map to the interfaces on which you want DCBX to exchange the application protocol information with connected peers. (See Related Documentation for how to define applications and configure application maps to interfaces, and for an example of the entire procedure that also includes classifier configuration.)

Note

In Junos OS Release 12.1, the FCoE application was configured by default, so you did not need to configure it in an application map. In Junos OS Release 12.2, if you want DCBX to advertise the FCoE application on an interface and you apply an application map to that interface, you must explicitly configure FCoE in the application map. You also must enable priority-based flow control (PFC) on the FCoE code point on all interfaces that you want to advertise FCoE. If you apply an application map to an interface, the interface sends DCBX TLVs only for the applications configured in the application map.

  • To apply an application map to a DCBX interface, specify the DCBX interface and the application map name:

    [edit protocols]

    user@switch# set dcbx interface interface-name application-map application-map-name



    For example, to apply an application map named ptp-app-map on interface xe-0/0/11:

    user@switch# set protocols dcbx interface xe-0/0/11 application-map ptp-app-map
