Manual Reference Pages - VDE_SWITCH (1)
vde_switch - Virtual Distributed Ethernet switch
is a virtual switch for the vde architecture.
A vde network can include several vde_switches running on different
vde_switches can be connected by vde cables (see
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.
vde-2 has several features: VLAN, Fast Spanning Tree Protocol, command line management
(on console for foreground switches, on a terminal for daemonized switches).
If a vde_switch run in foreground mode simply type return to have the prompt.
For daemons there is the -M option to specify the management socket. Unixterm is the tool
to start a terminal for the management.
Type "help" at the prompt for a list of possible options.
turn off the switch engine. It operates as a hub.
-sock commdirpath |
specify the directory when comm socket are created.
The default value is "/tmp/vde.ctl"
-mod octalmode |
specify the octal permissions for the comm sockets.
-group NAME |
specify the group owner for the comm socket.
The default value is the current users primary group
-tap interface |
connect the specified tuntap interface to this vde_switch (needs root privileges)
It is possible to specify several tap interfaces, comma separated.
Run as a daemon. Use syslog for logging.
-f rcfile |
rc file to set the initial switch configuration. This rc file has the same syntax of
the command line interface.

vde_switch is a modular program, options vary depending of the compiled-in modules.

VDE is a project by Renzo Davoli <email@example.com>
VDE started as an enhancement of uml_switch by Jeff Dike and others.
VDE-2 has been almost completely rewritten but maybe some statements
come from the historical source. So, some copyright and thanks also for Dike&Co.
