NAME
vde_switch - Virtual Distributed Ethernet switchSYNOPSIS
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.
