34# This script is designed for Sun Fire LX50, V60x and V65x systems.
35# It may work with other setups as long as you use the correct channel
36# and interface settings.  It can be used on the V20z as long as you
37# specify network settings on the command line.
38#
39# If the wrong channel is used you could lose network access to the
40# box because your BMC will be sending out bad Gratuitous ARP packets
41# with the wrong MAC address.  You will need to use a console or
42# override your local ARP cache with the correct addr.
