Dell PowerEdge FN I/O Module Configuration Guide 9.10(0.0)

To configure DCBx, follow these steps.

1. Enter INTERFACE Configuration mode. CONFIGURATION mode interface type slot/port
2. Enter LLDP Configuration mode to enable DCBx operation. INTERFACE mode [no] protocol lldp
3. Configure the DCBx version used on the interface, where: auto configures the port to operate using the DCBx version received from a peer. PROTOCOL LLDP mode [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 configuration source.
   • 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 DCB configuration 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-tlv ets-conf ets-reco. You can enable ETS recommend TLVs ( ets-reco) only if you enable ETS configuration 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: 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 FCoE and iSCSI, refer to Fibre Channel over Ethernet and iSCSI Optimization.
