devlink trap help
devlink trap show - display available packet traps and their
attributes
DEV - specifies the devlink device from which to show packet
traps. If this argument is omitted all packet traps of all
devices are listed.
trap TRAP - specifies the packet trap. Only applicable if a
devlink device is also specified.
devlink trap set - set attributes of a packet trap
DEV - specifies the devlink device the packet trap belongs to.
trap TRAP - specifies the packet trap.
action { trap | drop | mirror }
packet trap action.
trap - the sole copy of the packet is sent to the CPU.
drop - the packet is dropped by the underlying device and
a copy is not sent to the CPU.
mirror - the packet is forwarded by the underlying device
and a copy is sent to the CPU.
devlink trap group show - display available packet trap groups and
their attributes
DEV - specifies the devlink device from which to show packet trap
groups. If this argument is omitted all packet trap groups of
all devices are listed.
group GROUP - specifies the packet trap group. Only applicable
if a devlink device is also specified.
devlink trap group set - set attributes of a packet trap group
DEV - specifies the devlink device the packet trap group belongs
to.
group GROUP - specifies the packet trap group.
action { trap | drop | mirror }
packet trap action. The action is set for all the packet
traps member in the trap group. The actions of non-drop
traps cannot be changed and are thus skipped.
policer POLICER

trap group. A value of "0" will unbind the currently bound
policer.
nopolicer
Unbind packet trap policer from the packet trap group.
devlink trap policer set - set attributes of packet trap policer
DEV - specifies the devlink device the packet trap policer
belongs to.
policer POLICER - specifies the packet trap policer.
rate RATE - packet trap policer rate in packets per second.
burst BURST - packet trap policer burst size in packets.
devlink trap show

devlink -s trap group show pci/0000:01:00.0 group l2_drops
Show attributes and statistics of a specific packet trap
group.
devlink trap set pci/0000:01:00.0 trap source_mac_is_multicast
action trap
