homeyjoe, thanks for the info. It was helpful.

However, I have few comments:

1) On the VIO SERVER
I did mark YES Access external network & Trunk priority = 2

2) On the VIO SERVER
I did mark YES IEEE.Q Protocol
{ When I marked YES on this one, I couldn't ping from my laptop which is connected to the switch to the VIO SERVER which is also connected to the switch and when I un-marked it, I was able to ping from my laptop to the VIO server... But when it was marked YES, between the AIX servers (LPARS) I was able to ping the VIO Server.....I don't understand this one ? Can anyone explain }

3) To each AIX LPARs.. you mentioned I should not check YES Access external network & Trunk priority = ?
{could you please explain this... will I be able to access outside/external network}

4) As an experiment, I did check YES Access external network & Trunk priority = ? on each LPARs...
But when I give it the same Trunk Priority as VIO SERVER, my LPAR couldn't detect the Virtual Ethernet Adapter. As soon as the Trunk Priority number is different.. I can see the virtual adapter using cfgmgr.
{ -Do I need to check Access outside network for each LPAR ? }
{ -Should I always give different Trunk Priority and what does it mean ?}

Thanks

NAME

       ethers - Ethernet address to hostname database or domain

DESCRIPTION

       The  ethers  file  is  a local source of information about the (48-bit) Ethernet addresses of hosts on the Internet. The ethers file can be
       used in conjunction with or instead of other ethers sources, including the NIS maps ethers.byname and ethers.byaddr, the NIS+ table ethers,
       or Ethernet address data stored on an LDAP server. Programs use the ethers(3SOCKET) routines to access this information.

       The ethers file has one line for each host on an Ethernet. The line has the following format:

	      Ethernet-address official-host-name

       Items are separated by any number of SPACE and/or TAB characters. A `#' indicates the beginning of a comment extending to the end of line.

       The  standard  form  for  Ethernet  addresses is "x:x:x:x:x:x" where x is a hexadecimal number between 0 and ff, representing one byte. The
       address bytes are always in network order. Host names may contain any printable character other than SPACE, TAB, NEWLINE, or comment  char-
       acter.

FILES

       /etc/ethers
