Enabling Data Center Bridging
Data center bridging supports converged enhanced Ethernet (CEE) in a data center network. By default, DCB
is disabled. It must be enabled to support CEE.
NOTE: DCB is not supported on the Port Extender (PE) ports and cascade ports. For information about PE
ports, see Interface Types
• Priority-based flow control
• Enhanced transmission selection
• Data center bridging exchange protocol
• FCoE initialization protocol (FIP) snooping
DCB processes virtual local area network (VLAN)-tagged packets and dot1p priority values. Untagged packets
are treated with a dot1p priority of 0.
To enable DCB, enter the following command.
Enable DCB.
