DESCRIPTION
The
etherswitchcfg utility is used to configure an Ethernet switch built into the system.
etherswitchcfg accepts a number of options:
-
-f control file
-
Specifies the
etherswitch(4) control file that represents the switch to be configured. It defaults to
/dev/etherswitch0.
-
-m
-
When reporting port information, also list available media options for that port.
-
-v
-
Produce more verbose output. Without this flag, lines that represent inactive or empty configuration options are omitted.
config
The config command provides access to global switch configuration parameters. It support the following commands:
-
vlan_mode mode
-
Sets the switch VLAN mode (depends on the hardware).
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
phy is usually the port number, and
register is the register number. Both can be provided as decimal, octal or hexadecimal numbers in any of the formats understood by
strtol(3). To set the register value, use the form instance.register=value.
port
The port command selects one of the ports of the switch. It supports the following commands:
-
pvid number
-
Sets the default port VID that is used to process incoming frames that are not tagged.
-
media mediaspec
-
Specifies the physical media configuration to be configured for a port.
-
mediaopt mediaoption
-
Specifies a list of media options for a port. See
ifconfig(8) for details on
media and
mediaopt.
And the following flags (please note that not all flags are supported by all switch drivers):
-
addtag
-
Add VLAN tag to each packet sent by the port.
-
-addtag
-
Disable the add VLAN tag option.
-
striptag
-
Strip the VLAN tags from the packets sent by the port.
-
-striptag
-
Disable the strip VLAN tag option.
-
firstlock
-
This options makes the switch port lock on the first MAC address it sees. After that, usually you need to reset the switch to learn different MAC addresses.
-
-firstlock
-
Disable the first lock option. Note that sometimes you need to reset the switch to really disable this option.
-
dropuntagged
-
Drop packets without a VLAN tag.
-
-dropuntagged
-
Disable the drop untagged packets option.
-
doubletag
-
Enable QinQ for the port.
-
-doubletag
-
Disable QinQ for the port.
-
ingress
-
Enable the ingress filter on the port.
-
-ingress
-
Disable the ingress filter.
reg
The reg command provides access to the registers of the switch controller.
vlangroup
The vlangroup command selects one of the VLAN groups for configuration. It supports the following commands:
-
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 with this VID. Incoming frames carrying this tag will be forwarded according to the configuration of this VLAN group.
-
members port,...
-
Configures which ports are to be a member of this VLAN group. The port numbers are given as a comma-separated list. Each port can optionally be followed by “t” to indicate that frames on this port are tagged.
EXAMPLES
Configure VLAN group 1 with a VID of 2 and make ports 0 and 5 its members while excluding all other ports. Port 5 will send and receive tagged frames while port 0 will be untagged. Incoming untagged frames on port 0 are assigned to vlangroup1.
