Configuring Pfc Using The Web Interface - Dell PowerConnect 8024 User Configuration Manual

Operator configuration of PFC is used only when the port is configured in a
manual role. When interoperating with other equipment in a manual role,
the peer equipment must be configured with identical PFC priorities and
VLAN assignments. Interfaces not enabled for PFC ignore received PFC
frames. Ports configured in auto-upstream or auto-downstream roles receive
their PFC configuration from the configuration source and ignore any
manually configured information.
NOTE:
This feature is configurable on physical full duplex interfaces only. To
enable PFC on a LAG interface, the member interfaces must have the same
configuration.
When PFC is disabled, the interface defaults to the IEEE 802.3 flow control
setting for the interface. PFC is disabled by default.
If you enable priority-based flow control for a particular priority value on an
interface, ensure that Voice VLAN tagging is enabled on the interface so that
the 802.1p priority values are carried through the network (see "Voice VLAN"
on page 545). Additionally, make sure that 802.1p priority values are mapped
to CoS values (see "Configuring Class-of-Service" on page 1133).
PFC can be configured using the web interface and the command line
interface.
