DESCRIPTION <\/a> <\/h2>\n

devlink trap show – display available packet traps and their attributes<\/b>
DEV<\/i> – specifies the devlink device from which to show packet traps. If this argument is omitted all packet traps of all devices are listed.<\/p>\n

trap<\/b> TRAP<\/i> – specifies the packet trap. Only applicable if a devlink device is also specified.<\/p>\n

devlink trap set – set attributes of a packet trap<\/b>
DEV<\/i> – specifies the devlink device the packet trap belongs to.<\/p>\n

trap<\/b> TRAP<\/i> – specifies the packet trap.
action<\/b> { trap<\/b> | drop<\/b> | mirror<\/b> }<\/p>\n

packet trap action.<\/p>\n

trap<\/i> – the sole copy of the packet is sent to the CPU.<\/p>\n

drop<\/i> – the packet is dropped by the underlying device and a copy is not sent to the CPU.<\/p>\n

mirror<\/i> – the packet is forwarded by the underlying device and a copy is sent to the CPU.<\/p>\n

devlink trap group show – display available packet trap groups and their attributes<\/b>
DEV<\/i> – 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.<\/p>\n

group<\/b> GROUP<\/i> – specifies the packet trap group. Only applicable if a devlink device is also specified.<\/p>\n

devlink trap group set – set attributes of a packet trap group<\/b>
DEV<\/i> – specifies the devlink device the packet trap group belongs to.<\/p>\n

group<\/b> GROUP<\/i> – specifies the packet trap group.
action<\/b> { trap<\/b> | drop<\/b> | mirror<\/b> }<\/p>\n

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.<\/p>\n

policer<\/b> POLICER<\/i><\/p>\n

packet trap policer. The policer to bind to the packet trap group. A value of “0” will unbind the currently bound policer.<\/p>\n

nopolicer<\/b><\/p>\n

Unbind packet trap policer from the packet trap group.<\/p>\n

devlink trap policer set – set attributes of packet trap policer<\/b>
DEV<\/i> – specifies the devlink device the packet trap policer belongs to.<\/p>\n

policer<\/b> POLICER<\/i> – specifies the packet trap policer.<\/p>\n

rate<\/b> RATE<\/i> – packet trap policer rate in packets per second.<\/p>\n

burst<\/b> BURST<\/i> – packet trap policer burst size in packets.<\/p>\n
