Here is a small tips to change an SEA media speed without breaking it :
  • Bring interface down and detach it
# ifconfig en6 down detach

  • Set SEA defined :
# rmdev -l ent6

  • Set physical adapter defined :
# rmdev -l ent0

  • Change media speed on adapter :
# smitty chgenet
or
# chdev -l ent0 -a media speed=1000 Full Duplex -P

  • Add physical adapter back into system :
# mkdev -l ent0

  • Add SEA adapter back into system :
# mkdev -l ent6

# mkdev -l inet0
