32.Sh DESCRIPTION
33The
34.Nm
35utility is used to configure an Ethernet switch built into the system.
36.Nm
37accepts a number of options:
38.Bl -tag -width ".Fl f" -compact
39.It Fl "f control file"
40Specifies the
41.Xr etherswitch 4
42control file that represents the switch to be configured.
43It defaults to
44.Li /dev/etherswitch0 .
45.It Fl m
46When reporting port information, also list available media options for
47that port.
48.It Fl v
49Produce more verbose output.
50Without this flag, lines that represent inactive or empty configuration
51options are omitted.
52.El
53.Ss config
54The config command provides access to global switch configuration
55parameters.
56It support the following commands:
57.Bl -tag -width ".Ar vlan_mode mode" -compact
58.It Ar vlan_mode mode
59Sets the switch VLAN mode (depends on the hardware).
60.El
61.Ss phy
62The phy command provides access to the registers of the PHYs attached
63to or integrated into the switch controller.
64PHY registers are specified as phy.register,
65where
66.Ar phy
67is usually the port number, and
68.Ar register
69is the register number.
70Both can be provided as decimal, octal or hexadecimal numbers in any of the formats
71understood by
72.Xr strtol 4 .
73To set the register value, use the form instance.register=value.
74.Ss port
75The port command selects one of the ports of the switch.
76It supports the following commands:
77.Bl -tag -width ".Ar pvid number" -compact
78.It Ar pvid number
79Sets the default port VID that is used to process incoming frames that are not tagged.
80.It Ar media mediaspec
81Specifies the physical media configuration to be configured for a port.
82.It Ar mediaopt mediaoption
83Specifies a list of media options for a port.
84See
85.Xr ifconfig 8
86for details on
87.Ar media
88and
89.Ar mediaopt .
90.El
91And the following flags (please note that not all flags
92are supporterd by all switch drivers):
93.Bl -tag -width ".Ar addtag" -compact
94.It Ar addtag
95Add VLAN tag to each packet sent by the port.
96.It Ar -addtag
97Disable the add VLAN tag option.
98.It Ar striptag
99Strip the VLAN tags from the packets sent by the port.
100.It Ar -striptag
101Disable the strip VLAN tag option.
102.It Ar firstlock
103This options makes the switch port lock on the first MAC address it seems.
104After that, usually you need to reset the switch to learn different
105MAC addresses.
106.It Ar -firstlock
107Disable the first lock option.
108Note that sometimes you need to reset the
109switch to really disable this option.
110.It Ar dropuntagged
111Drop packets without a VLAN tag.
112.It Ar -dropuntagged
113Disable the drop untagged packets option.
114.It Ar doubletag
115Enable QinQ for the port.
116.It Ar -doubletag
117Disable QinQ for the port.
118.It Ar ingress
119Enable the ingress filter on the port.
120.It Ar -ingress
121Disable the ingress filter.
122.El
123.Ss reg
124The reg command provides access to the registers of the switch controller.
125.Ss vlangroup
126The vlangroup command selects one of the VLAN groups for configuration.
127It supports the following commands:
128.Bl -tag -width ".Ar vlangroup" -compact
129.It Ar vlan VID
130Sets the VLAN ID (802.1q VID) for this VLAN group.
131Frames transmitted on tagged member ports of this group will be tagged
132with this VID.
133Incoming frames carrying this tag will be forwarded according to the
134configuration of this VLAN group.
135.It Ar members port,...
136Configures which ports are to be a member of this VLAN group.
137The port numbers are given as a comma-separated list.
138Each port can optionally be followed by
139.Dq t
140to indicate that frames on this port are tagged.
141.El
142.Sh FILES
143.Bl -tag -width /dev/etherswitch? -compact
144.It Pa /dev/etherswitch?
145Control file for the ethernet switch driver.
146.El
147.Sh EXAMPLES
148Configure VLAN group 1 with a VID of 2 and makes ports 0 and 5 members,
149while excluding all other ports.
150Port 5 will send and receive tagged frames, while port 0 will be untagged.
151Incoming untagged frames on port 0 are assigned to vlangroup1.
