NAME

       vde_plug2tap - Virtual Distributed Ethernet plug-to-tap

SYNOPSIS

       vde_plug2tap [OPTION]... tap_name

DESCRIPTION

       vde_plug2tap  is  a  plug to be connected into a VDE switch.  All the data that is catched by the plug is
       sent to the tap interface tap_name and everything from that interface is injected in the switch.
       Example:
         vde_plug2tap tap4
       connects the default switch (/var/run/vde.ctl) to the tap4 interface.

OPTIONS

       -p, --port=portnum
              It is possible to decide which port of the switch to use.  When this option is not  specified  the
              switch assigns the first available unused port (if any).  It is possible to connect several cables
              in the same switch port: in this way all this cables work concurrently.  It means that packet  can
              result  as  duplicate  but  no  ARP  table  loops  are  generated.  Is useful when vde is used for
              mobility. Several physical interfaces can be used at a time during handoffs to prevent hichups  in
              connectivity.

       -g, --group=group
              group  ownership  of the communication socket. For security when more want to share a switch it is
              better to use a unix group to own the comm sockets so that the network traffic cannot be sniffed.

       -m, --mod=octal-mode
              octal chmod like permissions for the comm sockets

       -s, --sock=socket
              specify the UNIX socket to be used by local programs for joining the VDE.  The  default  value  is
              "/var/run/vde.ctl".   When '-' is used in place of the VDE switch directory, vde_plug2tap works as
              a plug (see vde_plug(1)).  The command:
                dpipe vde_plug = ssh remote.machine.org vde_plug2tap -s - tapx
              connects the default local switch to a remote tapx interface.

       -d, --daemon
              start vde_plug2tap as a background process

       -P, --pidfile=pidfile
              put the process ID of vde_plug2tap in pidfile. Can be used with --daemon  to  store  the  PID  for
              future killing.

       -h, --help
              show a brief help
