How to get a MAC address

[Dr. Richard Kopec]

I have an IBM RS/6000 7043 43P model 140 running AIX 5.3. Can anyone
tell me how to get it to tell me its MAC address?

Thanks!

Start with 'lsdev -C -c adapter | grep ent' to
to see what ethernet adapters AIX recognizes.
Then do 'lscfg -v -l ent0' (repeat for ent1,
etc. if you have multiple adapters) to see
what the burned-in MAC address is. Then do
'lsattr -E -l ent0' to see if a locally administered
address has been assigned to that adapter.

If the adapter is in use (by tcp/ip or some
other network protocol) you can also do
'netstat -v ent0' to see the address that
adapter presented to the switch/hub.

ifconfig -a

I think

netstat -i

is easiest
