`PKTIO`

Set/Display TX/PacketWatcher with streamlined pktio driver type

PKTIO

Show or switch which implementation the shell uses for TX and PacketWatcher. In PKTIO mode both commands go through the streamlined “PKTIO” packet driver instead, and they accept a smaller set of options. With no argument the command prints TX/PW using PKTIO mode is on (or off). on/off must be written in full. Any other word prints PKTIO subcommand '<word>' not found and the help.

Whether the mode can be switched depends on the pktio_driver_type setting in config.bcm. The mode is reset from that setting whenever the shell or the system is initialised. On SONiC Trident 3 PKTIO mode is normally off. pktio changes only which shell commands run; it does not touch the switch.

Hardware-validated

drivshell> pktio
TX/PW using PKTIO mode is off

PKTIO ON

Switch TX and PacketWatcher to the PKTIO driver. When pktio_driver_type is not set, it only prints PKTIO is not available when spn_PKTIO_DRIVER_TYPE = 0.

Unvalidated

drivshell> pktio on

PKTIO OFF

Switch back to the standard TX and PacketWatcher. When pktio_driver_type is set to 1 this is refused with Disabling PKTIO mode when spn_PKTIO_DRIVER_TYPE = 1 is not allowed.

Unvalidated

drivshell> pktio off

Built-in help

pktio [on|off]
    on   - Enable TX/PacketWatcher command with streamlined PKTIO driver type.
    off  - Disable TX/PacketWatcher command with streamlined PKTIO driver type.
NOTE: This command is used to switched different command parameter set according to PKTIO driver type.
      User should deploy spn_PKTIO_driver_type config to specify driver type.
