.Sh DESCRIPTION
|
|
.Nm
|
|
manages and inspects
|
|
.Xr vale 4
|
|
switches, for instance attaching and detaching interfaces, creating
|
|
and deleting persistent VALE ports, or listing the existing switches
|
|
and their ports.
|
|
In the following,
|
|
.Ar valeSSS
|
|
is the name of a VALE switch, while
|
|
.Ar valeSSS:PPP
|
|
is the name of a VALE port of
|
|
.Ar valeSSS .
|
|
.Pp
|
|
When issued without options it lists all the existing switch ports together
|
|
with their internal bridge number and port number.
|
|
.Bl -tag -width Ds
|
|
.It Fl g Ar valeSSS:PPP
|
|
Print the number of receive rings of
|
|
.Ar valeSSS:PPP .
|
|
.It Fl a Ar valeSSS:interface
|
|
Attach
|
|
.Ar interface
|
|
(which must be an existing network interface) to
|
|
.Ar valeSSS
|
|
and detach it from the host stack.
|
|
.It Fl h Ar valeSSS:interface
|
|
Attach
|
|
.Ar interface
|
|
(which must be an existing network interface) to
|
|
.Ar valeSSS
|
|
while keeping it attached to the host stack.
|
|
More precisely, packets coming from
|
|
the host stack and directed to the interface will go through the switch, where
|
|
they can still reach the interface if the switch rules allow it.
|
|
Conversely, packets coming from the interface will go through the switch and,
|
|
if appropriate, will reach the host stack.
|
|
.It Fl d Ar valeSSS:interface
|
|
Detach
|
|
.Ar interface
|
|
from
|
|
.Ar valeSSS .
|
|
.It Fl n Ar interface
|
|
Create a new persistent VALE port with name
|
|
.Ar interface .
|
|
The name must be different from any other network interface
|
|
already present in the system.
|
|
.It Fl d Ar interface
|
|
Destroy the persistent VALE port with name
|
|
.Ar inteface .
|
|
.It Fl l Ar valeSSS:PPP
|
|
Show the internal bridge number and port number of the given switch port.
|
|
.It Fl p Ar valeSSS:PPP
|
|
Enable polling mode for
|
|
.Ar valeSSS:PPP .
|
|
In polling mode, a dedicated kernel thread is spawned to handle packets
|
|
received from
|
|
.Ar valeSSS:PPP
|
|
and push them into the switch.
|
|
The kernel thread busy waits on the switch port rather than relying on
|
|
interrupts or notifications.
|
|
Polling mode can only be used on physical NICs attached to a VALE switch.
|
|
.It Fl P Ar valeSSS:PPP
|
|
Disable polling mode for
|
|
.Ar valeSSS:PPP .
|
|
.It Fl C Ar x | Ar x,y | Ar x,y,z | Ar x,y,z,w
|
|
When used in conjunction with
|
|
.Fl n
|
|
it supplies the number of tx and rx rings and slots.
|
|
The full format with four numbers gives, in order, number of tx slots, number
|
|
of rx slots, number of tx rings and number of rx rings.
|
|
The form with three numbers uses
|
|
.Ar z
|
|
for both the number of tx and the number of rx rings.
|
|
The forms with less than two numbers use the default values for the number
|
|
of rings.
|
|
The form with two numbers supplies the numbers of tx and rx slots.
|
|
The form with only one number uses
|
|
.Ar x
|
|
for both the number of tx and the number of rx slots.
|
|
.Pp
|
|
When used in conjunction with
|
|
.Fl p
|
|
only the first three forms are used.
|
|
The first number may be either 0 or 1.
|
|
If 0, then all interface rings will be polled by a single thread, running
|
|
on the core id given by the second number (the third number, if present,
|
|
must be 1).
|
|
If the first number is 1, then the ring identified by the second number will
|
|
be polled by the core with the same id.
|
|
If a third number is given, then this is repeated for as many consecutive
|
|
rings and cores.
|
|
.It Fl m Ar memid
|
|
Used in conjunction with
|
|
.Fl n
|
|
supplies the netmap memory region identifier to use together with the newly
|
|
created persistent VALE port.
|
|
These ports use a private memory region by default.
|
|
Using this option you can let them share memory with other ports.
|
|
Pass 1 as
|
|
.Ar memid
|
|
to use the global memory region already shared by all
|
|
harware netmap ports.
