[no] DCBx version {auto | cee | cin | ieee-v2.5}• cee: configures the port to use CEE (Intel 1.01).• cin: configures the port to use Cisco-Intel-Nuova (DCBx 1.0).• ieee-v2.5: configures the port to use IEEE 802.1Qaz (Draft 2.5).The default is Auto.4. Configure 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: configures the port to receive a peer configuration. The configuration source is elected from auto-upstream ports.• auto-downstream: configures the port to accept the internally propagated DCB configuration from a configurationsource.• config-source: configures the port to serve as the configuration source on the switch.• manual: configures the port to operate only on administer-configured DCB parameters. The port does not accept a DCBconfiguration received from a peer or a local configuration source.The default is Manual.5. On manual ports only: Configure 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 Configuration 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 configure the transmission of more than one TLV type at a time; for example, advertise DCBx-tlvets-conf ets-reco. You can enable ETS recommend TLVs (ets-reco) only if you enable ETS configurationTLVs (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: Configure 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 OptimizationTo verify the DCBx configuration on a port, use the show interface DCBx detail command.264 Data Center Bridging (DCB)
