VDE_SWITCH(1)                General Commands Manual               VDE_SWITCH(1)



NAME
       vde_switch - Virtual Distributed Ethernet switch

SYNOPSIS
       vde_switch [ -hub ] [ -sock socketpath ] [ -tap interface ] [ -daemon ]

DESCRIPTION
       A vde_switch is a virtual switch for the vde architecture.
       A vde network can include several vde_switches running on different
       (real) computers.  vde_switches can be connected by vde cables (see
       vde_plug (1) ).
       Supported architecture for VDE end nodes include: real linux boxes
       (through the tuntap interface), bochs, qemu and MPS virtual machines.
       VDE is useful to create networks of heterogeneous virtual machines as
       well as as a general tunneling tool -- all the ethernet based protocols
       work by this kind of tunnel -- and also as a tool for mobility.  In fact
       VDE creates an overlay network where users can keep their IP addresses
       despite of the change of IP addresses on the interfaces.

       vde_switch needs root privileges to open a tap interface, can be run by
       users when no -tap option is specified.


OPTIONS
       -hub,  turn off the switch engine. It operates as a hub.

       -sock socketpath ,
              specify the UNIX socket to be used by local programs for joining
              the VDE.  The default value is "/tmp/vde.ctl"

       -tap interface ,
              connect the specified tuntap interface to this vde_switch (needs
              root privileges)

       -daemon,
              Run as a daemon. Use syslog for logging.
