3. Enter Layer 2 Ethernet interface view.
interface interface-type interface-number
4. Enable LLDP on the interface.
lldp enable
By default, LLDP is enabled on an interface.
5. Enable the interface to advertise DCBX TLVs.
lldp tlv-enable dot1-tlv dcbx
By default, DCBX TLV advertisement is disabled on an interface.
Setting the DCBX version
Restrictions and guidelines
When you set the DCBX version, follow these restrictions and guidelines:
•
For DCBX to work correctly, configure the same DCBX version on the local port and peer port.
As a best practice, configure the highest version supported on both ends. IEEE Std
802.1Qaz-2011, DCBX Rev 1.01, and DCBX Rev 1.00 are in descending order.
•
After the configuration, LLDP frames sent by the local port carry information about the
configured DCBX version. The local port and peer port do not negotiate the DCBX version.
•
When the DCBX version is autonegotiated, the version IEEE Std 802.1Qaz-2011 is preferably
negotiated.
Procedure
1. Enter system view.
system-view
2. Enter Layer 2 Ethernet interface view.

3. Set the DCBX version.
dcbx version { rev100 | rev101 | standard }
By default, the DCBX version is not configured. It is autonegotiated by the local port and peer
port.
Configuring APP parameters
About APP parameters
The device negotiates with the server adapter by using the APP parameters to achieve the following
purposes:
•
Control the 802.1p priority values of the protocol packets that the server adapter sends.
•
Identify traffic based on the 802.1p priority values.
For example, the device can use the APP parameters to negotiate with the server adapter to set
802.1p priority 3 for all FCoE and FIP frames. When the negotiation succeeds, all FCoE and FIP
frames that the server adapter sends to the device carry the 802.1p priority 3.
Restrictions and guidelines
When you configure APP parameters, follow these restrictions and guidelines:
•
A Layer 2 ACL identifies application protocol packets by frame type.
•
An IPv4 advanced ACL identifies application protocol packets by TCP/UDP port number.
