Re: EtherChannel

the problem is due to the initial configuration of the
primary ethernet configuration was not properly
deleted from the ODM, I've had this problem multiple
times while initially deploying a new server.

you can resolve this the following way...asuming ent0
is the primary interface.

# first you have to make sure both Standard and 802.x
mode are down
ifconfig en0 down
ifconfig en0 detach
ifconfig et0 down
ifconfig et0 detach
# Remove the network interfaces from the ODM config,
along with their customization
# You can eliminate this step by issuing rmdev -dl
ent0 -R, but I'd rather make sure they go away.
rmdev -dl en0
rmdev -dl et0

# Remove the adapter definition
rmdev -dl ent0

# make sure they are gone
ifconfig -a

# redefine the adapter to the ODM
cfgmgr -v

#If you are using a specific media access speed you
have to redefine it here.. we usually use
100_Full_Duplex.

chdev -l ent0 -a media_speed=100_Full_Duplex

lsattr -El ent0

to make sure the changes took effect...

now define the etherchannel using your favorite
method.

Hi,

I had a similar problem once, I think it was
resolved by changing the Mode from standard to 802ad
or whatever the alternative is.

Good Morning,
I have a P52A that we setup etherchannel on to 2
cisco's. It is setup as primary and backup.
everything works great till reboot, when the system
comes up we have to reset the primary network cable
so the network comes up. Has anyone else had this
issue? What is the best way to setup an
etherchannel? We are using AIX 5.3 TL4 here is the
setup of the etherchannel:


Change / Show Characteristics of an EtherChannel /
Link Aggregation

Type or select values in entry fields.
Press Enter AFTER making all desired changes.


[Entry Fields]
EtherChannel / Link Aggregation
ent7
EtherChannel / Link Aggregation Adapters
ent0 +
Backup Adapter
ent4 +
Automatically Recover to Main Channel
yes +
Delete Backup Adapter
+
Add Main Adapter
+
Delete Main Adapter
+
Add Backup Adapter
+
Enable Alternate Address
no +
Alternate Address

Enable Gigabit Ethernet Jumbo Frames
no +

Hash Mode

Internet Address to Ping

Number of Retries

Retry Timeout (sec)

Thanks,
