Data Center Bridging (DCB)
Data center bridging (DCB) refers to a set of IEEE Ethernet enhancements that provide data centers with a
single, robust, converged network to support multiple traffic types, including local area network (LAN),
server, and storage traffic.
The Dell Networking Operating System (OS) commands for data center bridging features include
802.1Qbb priority-based flow control (PFC), 802.1Qaz enhanced transmission selection (ETS), and the
data center bridging exchange (DCBX) protocol.
advertise dcbx-appln-tlv
On a DCBX port with a manual role, configure the application priority TLVs advertised on the interface to
DCBX peers.

no advertise dcbx-appln-
tlv {fcoe | iscsi}
