SYNOPSIS

etherswitchcfg [-fcontrol file ] info etherswitchcfg [-fcontrol file ] config command parameter etherswitchcfg [-fcontrol file ] phy phy.register[=value] etherswitchcfg [-fcontrol file ] port%d [flags] command parameter etherswitchcfg [-fcontrol file ] reg register[=value] etherswitchcfg [-fcontrol file ] vlangroup%d command parameter

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.

FILES

/dev/etherswitch?
  Control file for the Ethernet switch driver.

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.

    # etherswitchcfg vlangroup1 vlan 2 members 0,5t port0 pvid 2
