Enabling LLDP and DCBX TLV advertising

To enable the device to advertise APP, ETS, and PFC data through an interface, enable LLDP globally and

enable LLDP and DCBX TLV advertising on the interface.
To enable LLDP and DCBX TLV advertising:

Step Command

Remarks

1.

Enter system view.

system-view

N/A

2.

Enable LLDP globally.

lldp global enable

By default, LLDP is disabled
globally.

3.

Enter Layer 2 Ethernet
interface view.

interface interface-type interface-number

N/A

4.

Enable LLDP.

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
advertising is disabled on an

interface.

Configuring APP parameters

The device negotiates with the server adapter by using the APP parameters to control the 802.1p priority

values of the protocol packets that the server adapter sends, and to 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 the 802.1p priority of all FCoE frames and FIP frames to 3. If the negotiation succeeds, all the FCoE

frames and FIP frames that the server adapter sends to the device carry the 802.1p priority 3.
To configure APP parameters:

Step Command

Remarks

1.

Enter system view.

N/A

2.

Create an Ethernet frame

header ACL or an IPv4
advanced ACL and enter ACL

view.

acl number acl-number [ name
acl-name ] [ match-order { auto |

config } ]

An Ethernet frame header ACL
number is in the range of 4000 to

4999. An IPv4 advanced ACL
number is in the range of 3000 to

3999.
DCBX Rev 1.00 supports only

Ethernet frame header ACLs. DCBX
Rev 1.01 and IEEE Std

802.1Qaz™-2011 support both

Ethernet frame header ACLs and
IPv4 advanced ACLs.

3.

Create a rule for the ACL.

For the Ethernet frame header

ACL:

rule [ rule-id ] permit type
protocol-type ffff

For the IPv4 advanced ACL:

rule [ rule-id ] permit { tcp |
udp } destination-port eq port

Create rules according to the type
of the ACL previously created.
