● 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.
● manual: configures the port to operate only on administer-configured DCB
parameters. The port does not accept a DCB configuration received form a peer
or a local configuration source.

9.3(0.0) Introduced on the FC Flex IO module installed in the M I/O Aggregator.
Usage
Information
DCBX requires that you enable LLDP to advertise DCBX TLVs to peers.
Configure DCBX operation at the INTERFACE level on a switch or globally on the switch. To verify the
DCBX configuration on a port, use the show interface dcbx detail command.
dcbx version
Configure the DCBX version used on the interface.
Syntax
dcbx version {auto | cee | cin | ieee-v2.5}
To remove the DCBX version, use the no dcbx version {auto | cee | cin | ieee-v2.5}
command.
Parameters
auto | cee | cin |
ieee-v2.5
Enter the DCBX version type used on the interface, where:
● auto: configures the port to operate using the DCBX version received from a
peer.
● 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 802.1az (Draft 2.5).
