ETHERSWITCHCFG(8)       FreeBSD System Manager's Manual      ETHERSWITCHCFG(8)

NAME
     etherswitchcfg - configure a built-in Ethernet switch

SYNOPSIS
     etherswitchcfg [-f control file] info
     etherswitchcfg [-f control file] config command parameter
     etherswitchcfg [-f control file] phy phy.register[=value]
     etherswitchcfg [-f control file] port%d [flags] command parameter
     etherswitchcfg [-f control file] reg register[=value]
     etherswitchcfg [-f control 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
