Thanks for the response.
I dont understand this sentence:
Without any configuration to en0 or en1, set up en2 as you normally
would a regular network adress.
Do you speak about IP or MAC-Adress? en0 and en1 wont have any ip,
right?
What did you configure for
Enable ALTERNATE ETHERCHANNEL address no
+
ALTERNATE ETHERCHANNEL address []
+
I simply cant get any information... there is not even help in smitty.

I just finished up with a couple adapters running backup mode.
The RedBook (5L differences) is a little grey on this instruction.
For both adapters on the system:
Remove all en0 and en1 interfaces
ifconfig en0 down
ifconfig en0 detach
rmdev -dl en0
rmdev -dl ent0
rmdev -dl et0
cfgmgr -v
After cfgmgr check to see if the adapters are 'available' again,
'lsdev -Cc adapter'.
I used 'smitty etherchannel' for the rest of the configuration.
Choose ent0 and ent1 to make up your etherchannel (the redbook describes
the fields on page 364). This will show up as en2. Without any
configuration to en0 or en1, set up en2 as you normally would a regular
network adress. 'smitty tcpip' minimum configuration. I tested this
yesterday and the failover works perfectly. One adapter will will sit
waiting for the other to fail and take over after the times you set in
the etherchannel setup. Mine came back after about a minute.
HTH,
Darryl

Hello,
I would like to use the 5L features
- dead gateway detection
- virtual ip address
- network interface backup mode
to keep the impact on my systems from defects on nics, switches,
routers as small as possible. All system have 2 nics.
Did anybody write a concept about this he likes to share?
Where can I find more precise information about these features?
All I have is
- Redbook 5L differences guide
