etherswitchcfg(8)

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.

led number style

Sets the display style for a given LED. Available styles are: default (usually flash on activity), on, off, and blink. Not all switches will support all styles.

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.

striptagingress

Strip the VLAN tags from the packets received by the port.

-striptagingress

Disable the strip VLAN tag on ingress 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.

droptagged

Drop packets with a VLAN tag.

-droptagged

Disable the drop tagged packets 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.

atu

The atu command provides access to the Address Translation Unit table of the switch, which maps MAC addresses to switch ports. It supports the following commands:

dump

Display the current ATU table entries. Each entry shows the MAC address and a bitmask of ports associated with it.

flush all

Remove all dynamic entries from the ATU table.

flush port number

Remove all dynamic ATU entries associated with port number.

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.
