5.4.1.7 DCBX Bridge requirements
Insert item g) into the lettered list in 5.4.1.7 as follows:
A device supporting DCBX shall
a) Support Link Layer Discovery Protocol (LLDP) transmit and receive mode (IEEE Std 802.1AB).
b) Support the DCBX ETS Configuration Type, Length, Value (TLV) (D.2.9).
c) Support the ETS Recommendation TLV (D.2.10).
d) Support the Priority-based Flow Control Configuration TLV (D.2.11).
e) Support the Application Priority TLV (D.2.12).
f) Support the asymmetric and symmetric DCBX state machines (38.4).
g) Support the Application VLAN TLV (D.2.15).
38. Data Center Bridging eXchange protocol (DCBX)
Change items e) and D) and insert a new item g), as follows:
38.1 Overview
This clause details DCBX, which is used by DCB devices to exchange configuration information with directly connected peers. The protocol may also be used for misconfiguration detection and for configuration of the peer.
This standard describes the base protocol, which comprises state machines and TLVs for capability exchange. For each feature that is supported by DCBX, the atributes that are to be exchanged specify
a)The attributes to be exchanged;
b)How the attributes are used for detecting misconfiguration; and
c) What action needs to be taken when a misconfiguration is detected.
The information listed above is specified for the following:
d)ETS;
e)PFC; and
f) Application Priority Configuration TLV: and
g) Application VLAN TLV.IEEE 802.1Qcd pdf download.
