Reference Guide

1. Configure ToR- and FCF-facing interfaces as auto-upstream ports.
2. Configure server-facing interfaces as auto-downstream ports.
3. Configure a port to operate in a configuration-source role.
4. Configure ports to operate in a manual role.
1. Enter INTERFACE Configuration mode.
CONFIGURATION mode
interface type slot/port
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.
