VETHER(4)               NetBSD Kernel Interfaces Manual              VETHER(4)


NAME

     vether -- virtual Ethernet interface


SYNOPSIS

     pseudo-device vether


DESCRIPTION

     The vether interface simulates a normal Ethernet interface by encapsulat-
     ing 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.
