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 (Refer to Step 3 in Configuring DCBx Globally on the Switch).
4 Configure the PFC and ETS TLVs to be advertised on
un-configured with a manual port-role, where:
• 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. ETS recommend TLVs (ets-reco)
can be enabled 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.
Default: All TLV types are enabled.
[no] advertise DCBx-tlv
{ets-conf | ets-reco | pfc}
[ets-conf | ets-reco | pfc]
[ets-conf | ets-reco | pfc]
PROTOCOL LLDP
5 Configure the Application Priority TLVs to be advertised
on un-configured with a manual port-role, where:
• fcoe enables the advertisement of FCoE in Application
Priority TLVs.
• iscsi enables the advertisement of iSCSI in
Application Priority TLVs.
Default: 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.
