Tired of remembering and typing in the ndd variables to check the speed and duplex settings of an ethernet port? This script automates the drudge work – just give it an interface type (hme, ce, bge) and an instance number, and it will tell you how that port is configured.

# This script will take 2 arguments - first one being the interface name 
# (ce, hme etc.) and the second one the instance number

# We'll then call ndd and pull up some information about speed and
# duplex settings

# Path to ndd
NDD=/usr/sbin/ndd

# Make sure we got our command line args
