VETHER(4)                    Device Drivers Manual                   VETHER(4)

NAME
     vether - virtual Ethernet interface

SYNOPSIS
     pseudo-device vether

DESCRIPTION
     The vether interface simulates a normal Ethernet interface by
     encapsulating standard network frames with an Ethernet header,
     specifically for use as a member in a bridge(4).

     To use vether the administrator needs to configure an address onto the
     interface so that packets can be routed to it.  An Ethernet header will
     be prepended and, if the vether interface is a member of a bridge(4), the
     frame will show up there.

     The vether link state can be controlled using ifconfig(8):

           media auto  link state "up"
           media none  link state "down"

SEE ALSO
     bridge(4), ifconfig(8)

HISTORY
     The vether interface first appeared in OpenBSD 4.7 and NetBSD 10.

BUGS
     Like tap(4), the Ethernet address chosen will be partially random, and
     may occasionally collide with another address.
