Configuring the DCBX Mode
You can configure the DCBX mode that an interface uses to communicate with the connected peer. Three DCBX modes are supported:
Autonegotiation—The interface negotiates with the connected peer to determine the DCBX mode. This is the default DCBX mode.
IEEE DCBX—The interface uses IEEE DCBX type, length, and value (TLV) to exchange DCBX information with the connected peer. QFX3500 Node devices come up with IEEE DCBX enabled by default and then autonegotiate with the connected peer to determine the final DCBX mode.
DCBX Version 1.01—The interface uses Converged Enhanced Ethernet (CEE) DCBX version 1.01 TLVs to exchange DCBX information with the connected peer. QFabric system Node devices other than QFX3500 switches come up with DCBX version 1.01 enabled by default and then autonegotiate with the connected peer to determine the final DCBX mode.
Pre-CEE (pre-DCB) versions of DCBX such as DCBX version 1.00 are not supported. If an interface receives an LLDP frame with pre-CEE DCBX TLVs, the system drops the frame.
Configure the DCBX mode by specifying the mode for one interface or for all interfaces.
To configure the DCBX mode, specify the interface and the mode:
content_copy zoom_out_map[edit protocols dcbx] user@switch# set interface interface-name dcbx-version (auto-negotiate | ieee-dcbx | dcbx-version-1.01)
For example, to configure DCBX version 1.01 on interface
xe-0/0/21:content_copy zoom_out_mapuser@switch# set protocols dcbx interface xe-0/0/21 dcbx-version dcbx-version-1.01
To configure IEEE DCBX on all interfaces:
content_copy zoom_out_mapuser@switch# set protocols dcbx interface all dcbx-version ieee-dcbx
