• cee: congures the port to use CEE (Intel 1.01).
• cin: congures the port to use Cisco-Intel-Nuova (DCBx 1.0).
• ieee-v2.5: congures the port to use IEEE 802.1Qaz (Draft 2.5).
The default is Auto.
4. Congure the DCBx port role the interface uses to exchange DCB information.
PROTOCOL LLDP mode
[no] DCBx port-role {config-source | auto-downstream | auto-upstream | manual}
• auto-upstream: congures the port to receive a peer conguration. The conguration source is elected from auto-
upstream ports.
• auto-downstream: congures the port to accept the internally propagated DCB conguration from a conguration
source.
• config-source: congures the port to serve as the conguration source on the switch.
• manual: congures the port to operate only on administer-congured DCB parameters. The port does not accept a DCB
conguration received from a peer or a local conguration source.
The default is Manual.
5. On manual ports only: Congure the PFC and ETS TLVs advertised to DCBx peers.
PROTOCOL LLDP mode
[no] advertise DCBx-tlv {ets-conf | ets-reco | pfc} [ets-conf | ets-reco | pfc] [ets-
conf | ets-reco | pfc]
• ets-conf: enables the advertisement of ETS Conguration TLVs.
• ets-reco: enables the advertisement of ETS Recommend TLVs.
• pfc enables: the advertisement of PFC TLVs.
The default is All PFC and ETS TLVs are advertised.
NOTE: You can congure the transmission of more than one TLV type at a time; for example, advertise DCBx-tlv
ets-conf ets-reco
. You can enable ETS recommend TLVs (ets-reco) only if you enable ETS conguration
TLVs (ets-conf).
To disable TLV transmission, use the no form of the command; for example, no advertise DCBx-tlv pfc ets-reco.
6. On manual ports only: Congure the Application Priority TLVs advertised on the interface to DCBx peers.
PROTOCOL LLDP mode
[no] advertise DCBx-appln-tlv {fcoe | iscsi}
• fcoe: enables the advertisement of FCoE in Application Priority TLVs.
• iscsi: enables the advertisement of iSCSI in Application Priority TLVs.
The default is Application Priority TLVs are enabled to advertise FCoE and iSCSI.
NOTE: To disable TLV transmission, use the no form of the command; for example, no advertise DCBx-appln-
tlv iscsi
.
For information about how to use iSCSI, refer to iSCSI Optimization
To verify the DCBx conguration on a port, use the show interface DCBx detail command.
