Determine Interface Status
From Peter Pap's Technowiki
The following script will give you the status of your active network interfaces, ie. duplex, speed, auto-negotiation etc. Was taken from a BigAdmin article:

# Simple script to GET stats about network cards
# Should work on hme and qfe. Will NOT change anything.
# Will report on speed and config of all network interfaces.
# Paul Bates 27.03.2000
# James Council 26.09.2001
# - Changed output to one liners.
# - Added IPversion check.
# James Council 10.10.2002 (jamescouncil@yahoo.com)
# - Added test for Cassini Gigabit-Ethernet card (ce_).
# - Added test for GEM Gigabit-Ethernet (ge_)
# - Added test for eri Fast-Ethernet (eri_).
# - Added "Ethernet Address" field.
# - Removed "IPversion" field.
# - Removed checking of a port more than once (i.e. qfe0 qfe0:1)
# James Council 10.25.2002 (jamescouncil@yahoo.com)
# - Fixed 1GB check on ge device.
# James Council 04.02.2003 (jamescouncil@yahoo.com)
# - Added dmfe check (suggested by John W. Rudick, & Erlend Tronsmoen)
# Octave Orgeron 02.06.2004 (unixconsole@yahoo.com)
# - Added bge check (bge_).
# Octave Orgeron 05.18.2005 (unixconsole@yahoo.com)
# - Corrected CE check to use kstat, which is required in Solaris 10.
# Octave Orgeron 12.13:2005 (unixconsole@yahoo.com)
# - Corrected CE and DMFE check. Added IPGE check. Special thanks to
# Paul Bates, Christian Jose, and Bill Qualye for suggesting fixes and
# for keeping me on my toes;)
# Octave Orgeorn 02.07.2007 (unixconsole@yahoo.com)
# - Added support for the Intel e1000g interfaces.
# - Cleaned up script. Housecleaning.
# - Tested against Fujitsu Quad GigE Nic's (FJGI)
# Paul Bates 10.03.2008 (sun@paulbates.org)
# - included NXGE interfaces, Thanks Jorg Weiss and Randy Latimer !!
# - Just tidied up code a little more, removed some fluff
#
# NOTE: For further updates or comments please feel free to contact me via
# email. James Council or Octave Orgeron or Paul Bates
