.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility is used to configure an Ethernet switch built into the system.

accepts a number of options:
|
|
.Bl -tag -width ".Fl f" -compact
|
|
.It Fl "f control file"
|
|
Specifies the
|
|
.Xr etherswitch 4
|
|
control file that represents the switch to be configured.
|
|
It defaults to
|
|
.Li /dev/etherswitch0 .
|
|
.It Fl m
|
|
When reporting port information, also list available media options for
|
|
that port.
|
|
.It Fl v
|
|
Produce more verbose output.
|
|
Without this flag, lines that represent inactive or empty configuration
|

options are omitted.
|
|

It support the following commands:
|
|
.Bl -tag -width ".Ar vlan_mode mode" -compact
|
|
.It Ar vlan_mode mode
|
|
Sets the switch VLAN mode (depends on the hardware).
|
|
.El
|
|
.Ss phy
|
|
The phy command provides access to the registers of the PHYs attached
|
|
to or integrated into the switch controller.
|
|
PHY registers are specified as phy.register,
|
|
where
|
|
.Ar phy
|
|
is usually the port number, and
|
|
.Ar register
|
|
is the register number.
|
|
Both can be provided as decimal, octal or hexadecimal numbers in any of the formats
|
|
understood by
|
|
.Xr strtol 3 .
|
|
To set the register value, use the form instance.register=value.
|
|
.Ss port
|
|
The port command selects one of the ports of the switch.
|
|
It supports the following commands:
|
|
.Bl -tag -width ".Ar pvid number" -compact
|
|
.It Ar pvid number
|
|
Sets the default port VID that is used to process incoming frames that are not tagged.
|
|
.It Ar media mediaspec
|
|
Specifies the physical media configuration to be configured for a port.
|
|
.It Ar mediaopt mediaoption
|
|
Specifies a list of media options for a port.
|
|
See
|
|
.Xr ifconfig 8

Disable the first lock option.

|
.Bl -tag -width ".Ar vlangroup" -compact
|
|
.It Ar vlan VID

Sets the VLAN ID (802.1q VID) for this VLAN group.
|
|
Frames transmitted on tagged member ports of this group will be tagged

Incoming frames carrying this tag will be forwarded according to the
|
|
configuration of this VLAN group.
|
|
.It Ar members port,...
|
|
Configures which ports are to be a member of this VLAN group.
|
|
The port numbers are given as a comma-separated list.
|

.Sh FILES
|
|
.Bl -tag -width /dev/etherswitch? -compact
