Configuring DCBx Globally on the Switch

To globally configure the DCBx operation on a switch, follow these steps.

1. Enter Global Configuration mode.
   EXEC PRIVILEGE mode
   configure
2. Enter LLDP Configuration mode to enable DCBx operation.
   CONFIGURATION mode
   [no] protocol lldp
3. Configure the DCBx version used on all interfaces not already configured to exchange DCB information.
   PROTOCOL LLDP mode
   [no] DCBx version {auto | cee | cin | ieee-v2.5}
   • auto: configures all ports to operate using the DCBx version received from a peer.
   • cee: configures a port to use CEE (Intel 1.01). cin configures a port to use Cisco-Intel-Nuova (DCBx 1.0).
   • ieee-v2.5: configures a port to use IEEE 802.1Qaz (Draft 2.5).
   The default is Auto.
   NOTE To configure the DCBx port role the interfaces use to exchange DCB information, use the DCBx port-role command in INTERFACE Configuration mode (Step 3).
4. Configure the PFC and ETS TLVs that advertise on unconfigured interfaces with a manual port-role.
   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 transmission of ETS Configuration TLVs.
   • ets-reco: enables transmission of ETS Recommend TLVs.
   • pfc: enables transmission of PFC TLVs.
   NOTE You can configure the transmission of more than one TLV type at a time. You can only enable ETS recommend TLVs (ets-reco) 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.
   The default is All TLV types are enabled.
5. Configure the Application Priority TLVs that advertise on unconfigured interfaces with a manual port-role.
   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 and advertise FCoE and iSCSI.
   NOTE To disable TLV transmission, use the no form of the command; for example, no advertise DCBx-appln-tlv iscsi.
6. Configure the FCoE priority advertised for the FCoE protocol in Application Priority TLVs.
   PROTOCOL LLDP mode
   [no] fcoe priority-bits priority-bitmap
   The priority-bitmap range is from 1 to FF.
   The default is 0x8.
7. Configure the iSCSI priority advertised for the iSCSI protocol in Application Priority TLVs.
   PROTOCOL LLDP mode
   [no] iscsi priority-bits priority-bitmap
   The priority-bitmap range is from 1 to FF.
   The default is 0x10.
