# This script is designed for Sun Fire LX50, V60x and V65x systems.

# It may work with other setups as long as you use the correct channel

# and interface settings.  It can be used on the V20z as long as you

# specify network settings on the command line.

#

# If the wrong channel is used you could lose network access to the

# box because your BMC will be sending out bad Gratuitous ARP packets

# with the wrong MAC address.  You will need to use a console or

# override your local ARP cache with the correct addr.
