CONFIGURATION mode
interface type slot/port[/subport]
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.
