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.
If you use the auto-upstream option and the port does not come up on a switch from a different
vendor, manually configure the version a CEE on the peer device.
dcbx version
Configure the DCBX version used on the interface.
Syntax
dcbx version {auto | cee | ieee-v2.5}
To remove the DCBX version, use the dcbx version {auto | cee | ieee-v2.5} command.
Parameters
auto | cee | 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 CDD (Intel 1.01).
● ieee-v2: configures the port to use IEEE 802.1az (Draft 2.5).

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.
debug dcbx
Enable DCBX debugging.
Syntax
debug dcbx {all | auto-detect-timer | config-exchng | fail | mgmt |
resource | sem | tlv}
To disable DCBX debugging, use the no debug dcbx command.
Parameters
{all | auto-
detect-timer |
config-exchng |
fail | mgmt |
Enter the type of debugging, where:
● all: enables all DCBX debugging operations.
● auto-detect-timer: enables traces for DCBX auto-detect timers.
● config-exchng: enables traces for DCBX configuration exchanges.
