Priority-Flow-Control - HP 5900 series Command Reference Manual

When you configure the suppression threshold in pps or kbps, the device may convert the configured
value into a multiple of a certain step supported by the chip. As a result, the actual suppression threshold
may be different from the configured one. To determine the suppression threshold that takes effect, see
the prompts on the device.
Examples
# Set the multicast storm suppression threshold to 10000 kbps on Ten-GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1

priority-flow-control

Use priority-flow-control to enable PFC on an Ethernet interface through automatic negotiation or
forcibly.
Use undo priority-flow-control to disable PFC on the interface.
Syntax
priority-flow-control { auto | enable }
undo priority-flow-control
Default
PFC is disabled on Ethernet interfaces.
Views
Ethernet interface view
Predefined user roles
network-admin
Parameters
auto: Specifies the Ethernet interface to automatically negotiate with its peer to enable PFC.
enable: Forcibly enables PFC.
Usage guidelines
A port can receive PFC pause frames regardless of whether PFC is enabled on the port. However, only
a port with PFC enabled can process PFC pause frames. Therefore, to make PFC take effect, make sure
that PFC is enabled on both the local end and the peer end.
Examples
# Configure Ten-GigabitEthernet 1/0/1 to automatically negotiate with its peer to enable PFC.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] priority-flow-control auto
