Priority-Based Flow Control (Pfc); Data Center Bridging (Dbc) Exchange Protocol; Fibre Channel Over Ethernet (Fcoe) Initialization Protocol Snooping - Dell PowerConnect 8024 User Configuration Manual

Priority-based Flow Control (PFC)

The Priority-based Flow Control feature allows the user to pause or inhibit
transmission of individual priorities within a single physical link. By
configuring PFC to pause a congested priority (priorities) independently,
protocols that are highly loss sensitive can share the same link with traffic that
has different loss tolerances. Priorities are differentiated by the priority field
of the 802.1Q VLAN header.
NOTE:
An interface that is configured for PFC is automatically disabled for 802.3x
flow control.
For information about configuring the PFC feature, see "Configuring Data
Center Features" on page 807.

Data Center Bridging (DBC) Exchange Protocol

The Data Center Bridging Exchange Protocol (DCBX) is used by DCB
devices to exchange configuration information with directly connected peers.
The protocol is also used to detect misconfiguration of the peer DCB devices
and optionally, for configuration of peer DCB devices. For information about
configuring DCBx settings, see "Configuring Data Center Features" on
page 807.

Fibre Channel over Ethernet (FCoE) Initialization Protocol Snooping

The FCoE Initialization Protocol (FIP) is used to perform the functions of
FC_BB_E device discovery, initialization, and maintenance as defined in the
ANSI T11 FC-BB-5 specification. The PC8024/PC8024F switch supports FIP
snooping, which is a frame inspection method used by FIP Snooping Bridges
to monitor FIP frames and apply policies based upon the L2 header
information in those frames. For information about configuring the FIP
Snooping feature, see "Configuring Data Center Features" on page 807.
