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.
