Configuring DCBx Globally on the Switch
To globally configure DCBx operation on a switch, follow these steps:
5 On manual ports only:
Configure the PFC and ETS TLVs advertised to DCBx
peers, where:
•
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.
Default: 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 ETS configuration TLVs (ets-conf) are enabled. To
disable TLV transmission, use the no form of the command;
for example, no advertise DCBx-tlv pfc ets-reco.
[no] advertise DCBx-tlv
{ets-conf | ets-reco | pfc}
[ets-conf | ets-reco | pfc]
[ets-conf | ets-reco | pfc]
PROTOCOL LLDP
6 On manual ports only:
Configure the Application Priority TLVs advertised on the
interface to DCBx peers, where:
•
fcoe enables the advertisement of FCoE in Application
Priority TLVs.
•
iscsi enables the advertisement of iSCSI in Application
Priority TLVs.
Default: To advertise FCoE and iSCSI, Application
Priority TLVs are enabled.
Note: To disable TLV transmission, enter the no form of the
command; for example, no advertise DCBx-appln-tlv iscsi.
For information about how to use FCoE and iSCSI, see
FCoE Transit and
iSCSI Optimization.
[no] advertise
DCBx-appln-tlv {fcoe | iscsi}

CONFIGURATION
3 Configure the DCBx version used on all not already
configured to exchange DCB information, where:
•
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).
Default: Auto.
[no] DCBx version {auto | cee
| cin | ieee-v2.5}
PROTOCL LLDP
Note: You can configure the DCBx port role to exchange DCB information by using the DCBx port-role command in
INTERFACE Configuration mode (see Step 3 in Configuring DCBx Globally on the Switch).
