Hello Wai,
EXAMPLES
-------------
The following commands will set up Ethernet interfaces fxp0 to deliver
packets alternating over the physical interfaces corresponding to net-
working interfaces fxp0 through fxp3:
# Plumb nodes together
ngctl mkpeer fxp0: one2many upper one
ngctl connect fxp0: fxp0:upper lower many0
ngctl connect fxp1: fxp0:upper lower many1
ngctl connect fxp2: fxp0:upper lower many2
ngctl connect fxp3: fxp0:upper lower many3
# Allow fxp1 through fxp3 to xmit/recv fxp0 frames
ngctl msg fxp1: setpromisc 1
ngctl msg fxp3: setpromisc 1
ngctl msg fxp2: setpromisc 1
ngctl msg fxp1: setautosrc 0
ngctl msg fxp3: setautosrc 0
ngctl msg fxp2: setautosrc 0
# Configure all four links as up
ngctl msg fxp0:upper \
setconfig "{ xmitAlg=1 failAlg=1 enabledLinks={ 1 1 1 1 } }"
# Bring up interface
ifconfig fxp0 192.168.1.1 netmask 0xfffffffc
With a similar setup on a peer machine (using the address 192.168.1.2),
a
point-to-point Ethernet connection with four times normal bandwidth is
achieved.
Later.
