70 Switch Features
For information about configuring the PFC feature, see "Configuring Data
Center Bridging Features" on page 809.
Data Center Bridging Exchange (DBCx) 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 Bridging Features"
on page 809. DCBx is a link-local protocol and operates only on individual
links. When configuring FIP snooping on a port channel, ensure that all of
the physical links in the port channel utilize the same auto configuration
setting.
Enhanced Transmission Selection
Enhanced Transmission Selection (ETS) allows the switch to allocate
bandwidth to traffic classes and share unused bandwidth with lower-priority
traffic classes while coexisting with strict-priority traffic classes. ETS is
supported on the PowerConnect 8100-series switches and can be configured
manually or automatically using the auto configuration feature. For more
information about ETS, see "Enhanced Transmission Selection" on page 831.
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 Bridging Features" on
page 809.
