Reference Guide

– 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 FCoE Initialization Protocol (FIP) Snooping and iSCSI
Optimization.
To verify the DCBx configuration on a port, use the show interface DCBx detail command.
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.
PROTOCL LLDP mode
[no] DCBx version {auto | cee | cin | ieee-v2.5}
