Testpmd Runtime Functions
=========================
Where the testpmd application is started in interactive mode, (-i|--interactive),
it displays a prompt that can be used to start and stop forwarding,
configure the application, display statistics, set the Flow Director and other tasks.
.. code-block:: console
testpmd>
The testpmd prompt has some, limited, readline support.
Common bash command- line functions such as Ctrl+a and Ctrl+e to go to the start and end of the prompt line are supported
as well as access to the command history via the up-arrow.
There is also support for tab completion.
If you type a partial command and hit <TAB> you get a list of the available completions:
.. code-block:: console
testpmd> show port <TAB>
info [Mul-choice STRING]: show|clear port info|stats|fdir|stat_qmap X
info [Mul-choice STRING]: show|clear port info|stats|fdir|stat_qmap all
stats [Mul-choice STRING]: show|clear port info|stats|fdir|stat_qmap X
stats [Mul-choice STRING]: show|clear port info|stats|fdir|stat_qmap all
...

Configuration Functions
-----------------------
The testpmd application can be configured from the runtime as well as from the command-line.
This section details the available configuration functions that are available.
.. note::
Configuration changes only become active when forwarding is started/restarted.
set default
~~~~~~~~~~~
Reset forwarding to the default configuration:
set default
set verbose
~~~~~~~~~~~
Set the debug verbosity level:
set verbose (level)
Currently the only available levels are 0 (silent except for error) and 1 (fully verbose).
set nbport
~~~~~~~~~~
Set the number of ports used by the application:
set nbport (num)
This is equivalent to the --nb-ports command-line option.
set nbcore
~~~~~~~~~~
Set the number of cores used by the application:
set nbcore (num)
This is equivalent to the --nb-cores command-line option.
.. note::
The number of cores used must not be greater than number of ports used multiplied by the number of queues per port.
set coremask
~~~~~~~~~~~~
Set the forwarding cores hexadecimal mask:
set coremask (mask)
This is equivalent to the --coremask command-line option.
.. note::
The master lcore is reserved for command line parsing only and cannot be masked on for packet forwarding.
set portmask
~~~~~~~~~~~~
Set the forwarding ports hexadecimal mask:
set portmask (mask)
This is equivalent to the --portmask command-line option.
set burst
~~~~~~~~~
Set number of packets per burst:
set burst (num)

In mac_retry forwarding mode, the transmit delay time and number of retries can also be set.
set burst tx delay (micrseconds) retry (num)
set txpkts
~~~~~~~~~~
Set the length of each segment of the TX-ONLY packets:
set txpkts (x[,y]*)
Where x[,y]* represents a CSV list of values, without white space.

set corelist (x[,y]*)
For example, to change the forwarding cores:
.. code-block:: console
testpmd> set corelist 3,1
testpmd> show config fwd
io packet forwarding - ports=2 - cores=2 - streams=2 - NUMA support disabled
Logical Core 3 (socket 0) forwards packets on 1 streams:
RX P=0/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:01
Logical Core 1 (socket 0) forwards packets on 1 streams:
RX P=1/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
.. note::
The cores are used in the same order as specified on the command line.
set portlist
~~~~~~~~~~~~
Set the list of forwarding ports:
set portlist (x[,y]*)
For example, to change the port forwarding:
.. code-block:: console
testpmd> set portlist 0,2,1,3
testpmd> show config fwd
io packet forwarding - ports=4 - cores=1 - streams=4
Logical Core 3 (socket 0) forwards packets on 4 streams:

~~~~~~~~~~~
Add a VLAN ID, or all identifiers, to the set of VLAN identifiers filtered by port ID:
rx_vlan add (vlan_id|all) (port_id)
.. note::
VLAN filter must be set on that port. VLAN ID < 4096.
Depending on the NIC used, number of vlan_ids may be limited to the maximum entries
in VFTA table. This is important if enabling all vlan_ids.

~~~~~~~~
Select hardware or software calculation of the checksum when
transmitting a packet using the csum forward engine:
csum set (ip|udp|tcp|sctp|outer-ip) (hw|sw) (port_id)
- ip|udp|tcp|sctp always concern the inner layer.
- outer-ip concerns the outer IP layer (only for IPv4) in case the packet is recognized
as a tunnel packet by the forward engine (vxlan, gre and ipip are
supported). See "csum parse-tunnel" command.
.. note::
Check the NIC Datasheet for hardware limits.
csum parse-tunnel
~~~~~~~~~~~~~~~~~
Define how tunneled packets should be handled by the csum forward
engine.
csum parse-tunnel (on|off) (tx_port_id)
If enabled, the csum forward engine will try to recognize supported
tunnel headers (vxlan, gre, ipip).
If disabled, treat tunnel packets as non-tunneled packets (a inner
header is handled as a packet payload).
.. note::
The port argument is the TX port like in the "csum set" command.
Example:
Consider a packet as following:
"eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in"
- If parse-tunnel is enabled, the ip|udp|tcp|sctp parameters of "csum
set" command are about inner headers (here ipv4_in and tcp_in), and the
outer-ip parameter is about outer headers (here ipv4_out).
- If parse-tunnel is disabled, the ip|udp|tcp|sctp parameters of "csum
set" command are about outer headers, here ipv4_out and udp_out.

tso show (port_id)
set fwd
~~~~~~~
Set the packet forwarding mode:
set fwd (io|mac|mac_retry|macswap|flowgen|rxonly|txonly|csum|icmpecho)
The available information categories are:
* io: forwards packets "as-is" in I/O mode.
This is the fastest possible forwarding operation as it does not access packets data.
This is the default mode.
* mac: changes the source and the destination Ethernet addresses of packets before forwarding them.
* mac_retry: same as "mac" forwarding mode, but includes retries if the destination queue is full.
* macswap: MAC swap forwarding mode.
Swaps the source and the destination Ethernet addresses of packets before forwarding them.
* flowgen: multi-flow generation mode.
Originates a bunch of flows (varying destination IP addresses), and terminate receive traffic.
* rxonly: receives packets but doesn't transmit them.
* txonly: generates and transmits packets without receiving any.
* csum: changes the checksum field with HW or SW methods depending on the offload flags on the packet.
* icmpecho: receives a burst of packets, lookup for IMCP echo requests and, if any, send back ICMP echo replies.
* ieee1588: demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX. Requires ``CONFIG_RTE_LIBRTE_IEEE1588=y``.
Note: TX timestamping is only available in the "Full Featured" TX path. To force ``testpmd`` into this mode set ``--txqflags=0``.

Port Functions
--------------
The following sections show functions for configuring ports.
.. note::
Port configuration changes only become active when forwarding is started/restarted.
port attach
~~~~~~~~~~~
Attach a port specified by pci address or virtual device args.
To attach a new pci device, the device should be recognized by kernel first.
Then it should be moved under DPDK management.
Finally the port can be attached to testpmd.
For example, to move a pci device using ixgbe under DPDK management:
.. code-block:: console
./tools/dpdk_nic_bind.py --status
Network devices using DPDK-compatible driver
============================================
<none>
Network devices using kernel driver
===================================
0000:0a:00.0 '82599ES 10-Gigabit SFI/SFP+ Network Connection' if=eth2 drv=ixgbe unused=
./tools/dpdk_nic_bind.py -b igb_uio 0000:0a:00.0
./tools/dpdk_nic_bind.py --status
Network devices using DPDK-compatible driver
============================================
0000:0a:00.0 '82599ES 10-Gigabit SFI/SFP+ Network Connection' drv=igb_uio unused=
To attach a port created by virtual device, above steps are not needed.
port attach (identifier)
For example, to attach a port whose pci address is 0000:0a:00.0.
.. code-block:: console
testpmd> port attach 0000:0a:00.0
Attaching a new port...
EAL: PCI device 0000:0a:00.0 on NUMA socket -1
EAL: probe driver: 8086:10fb rte_ixgbe_pmd
EAL: PCI memory mapped at 0x7f83bfa00000
EAL: PCI memory mapped at 0x7f83bfa80000
PMD: eth_ixgbe_dev_init(): MAC: 2, PHY: 18, SFP+: 5
PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x10fb
Port 0 is attached. Now total ports is 1
Done
testpmd>
For example, to attach a port created by pcap PMD.
.. code-block:: console
testpmd> port attach eth_pcap0
Attaching a new port...
PMD: Initializing pmd_pcap for eth_pcap0
PMD: Creating pcap-backed ethdev on numa socket 0
Port 0 is attached. Now total ports is 1
Done
testpmd>
In this case, identifier is "eth_pcap0".
This identifier format is the same as "--vdev" format of DPDK applications.
For example, to re-attach a bonded port which has been previously detached,
the mode and slave parameters must be given.
.. code-block:: console
testpmd> port attach eth_bond_testpmd_0,mode=0,slave=1
Attaching a new port...
EAL: Initializing pmd_bond for eth_bond_testpmd_0
EAL: Create bonded device eth_bond_testpmd_0 on port 0 in mode 0 on socket 0.
Port 0 is attached. Now total ports is 1
Done
port detach
~~~~~~~~~~~
Detach a specific port.
Before detaching a port, the port should be closed.
port detach (port_id)
For example, to detach a pci device port 0.
.. code-block:: console
testpmd> port close 0
Closing ports...
Done
testpmd> port detach 0
Detaching a port...
EAL: PCI device 0000:0a:00.0 on NUMA socket -1
EAL: remove driver: 8086:10fb rte_ixgbe_pmd
EAL: PCI memory unmapped at 0x7f83bfa00000
EAL: PCI memory unmapped at 0x7f83bfa80000
Done
testpmd>
For example, to detach a virtual device port 0.
.. code-block:: console
testpmd> port close 0
Closing ports...
Done
testpmd> port detach 0
Detaching a port...
PMD: Closing pcap ethdev on numa socket 0
Port 'eth_pcap0' is detached. Now total ports is 0
Done
testpmd>
To remove a pci device completely from the system, first detach the port from testpmd.
Then the device should be moved under kernel management.
Finally the device can be removed using kernel pci hotplug functionality.
For example, to move a pci device under kernel management:
.. code-block:: console
./tools/dpdk_nic_bind.py -b ixgbe 0000:0a:00.0
./tools/dpdk_nic_bind.py --status
Network devices using DPDK-compatible driver
============================================
<none>
Network devices using kernel driver
===================================
0000:0a:00.0 '82599ES 10-Gigabit SFI/SFP+ Network Connection' if=eth2 drv=ixgbe unused=igb_uio
To remove a port created by a virtual device, above steps are not needed.

For example, to create a bonded device in mode 1 on socket 0.
.. code-block:: console
testpmd> create bonded 1 0
created new bonded device (port X)
add bonding slave
~~~~~~~~~~~~~~~~~
Adds Ethernet device to a Link Bonding device:

Register Functions
------------------
The Register functions can be used to read from and write to registers on the network card referenced by a port number.
This is mainly useful for debugging purposes.
Reference should be made to the appropriate datasheet for the network card for details on the register addresses
and fields that can be accessed.
read reg
~~~~~~~~
Display the value of a port register:
read reg (port_id) (address)
For example, to examine the Flow Director control register (FDIRCTL, 0x0000EE000) on an Intel® 82599 10 GbE Controller:
.. code-block:: console
testpmd> read reg 0 0xEE00
port 0 PCI register at offset 0xEE00: 0x4A060029 (1241907241)
read regfield
~~~~~~~~~~~~~

flow_director_filter
~~~~~~~~~~~~~~~~~~~~
The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues.
Two types of filtering are supported which are referred to as Perfect Match and Signature filters, the match mode
is set by the --pkt-filter-mode command-line parameter:
* Perfect match filters.
The hardware checks a match between the masked fields of the received packets and the programmed filters.
* Signature filters.
The hardware checks a match between a hash-based signature of the masked fields of the received packet.
The Flow Director filters can match the different fields for different type of packet: flow type, specific input set
per flow type and the flexible payload. The Flow Director can also mask out parts of all of these fields so that filters
are only applied to certain fields or parts of the fields.
Different NICs may have different capabilities, command show port fdir (port_id) can be used to acquire the information.
