trapTRAP - 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.
trapTRAP - specifies the packet trap.
- action { trap | drop | mirror }
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.
groupGROUP - 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.
groupGROUP - 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.
- policerPOLICER
packet trap policer. The policer to bind to the packet 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.
policerPOLICER - specifies the packet trap policer.
rateRATE - packet trap policer rate in packets per second.
burstBURST - packet trap policer burst size in packets.
