User Guidelines
NOTE: This command is only available on N40xx series switches.
Datacenter bridging mode is only available on physical interfaces, not on
port-channel interfaces. To ensure proper operation, users must configure all
physical interfaces in a port channel to have the same data-center bridging
configuration.
Example
console#config
console(config)#interface range ethernet all
console(config-if)#datacenter-bridging
console(config-if-dcb)#priority-flow-control mode on
console(config-if-dcb)#priority-flow-control priority 1 no-drop
lldp dcbx version
Use the lldp dcbx version command in Global Configuration mode to
configure the administrative version for the Data Center Bridging Capability
Exchange (DCBX) protocol. This command enables the switch to support a
specific version of the DCBX protocol or to detect the peer version and match
it. DCBX can be configured to operate in IEEE mode or CEE mode or CIN
mode. In auto mode, version detection is based on the peer device DCBX
version. The switch operates in either IEEE or one of the legacy modes on
each interface.
NOTE: CIN is Cisco Intel Nuova DCBX (version 1.0). CEE is converged enhanced
ethernet DCBX (version 1.06).
Use the no form of the command to reset the dcbx version to the default
value of auto.
