DCB Tab Field Definitions
• DCBX State - The current DCBX (Data Center discovery and Capability exchange protocol)
state (enabled or disabled).
• DCBX Mode - The DCBX mode can be either DCB or CIN.
• LLDP Transmit State - DCBX uses Link Layer Discovery Protocol (LLDP) to exchange
parameters between two link peers. For the DCBX protocol to operate correctly, both LLDP Rx
and Tx must be enabled. If either Rx or Tx is disabled, DCBX is disabled.
• LLDP Receive State - DCBX uses LLDP to exchange parameters between two link peers. For
the DCBX protocol to operate correctly, both LLDP Rx and Tx must be enabled. If either Rx or Tx
is disabled, DCBX is disabled.
PFC Properties Area
• State - Enabled means that flow control in both directions (Tx and Rx) is enabled.
• Active Priority - Lists the priorities with PFC set to Enabled.
• Sync’d - If yes, the PFC priorities have been set by the peer. This parameter cannot be set.
Note: DCBX mode also configures FIP mode. If DCBX mode is DCB, FIP is enabled. If it is
CIN, FIP is disabled.
