I found the answer to this.
It is necessary on the AIX partition to set up an ethernet interface of the type vlan to get the packets tagged outbound.
This can be done via smitty vlan
This creates an interface similar to what you see with etherchannel. The ip number then needs assigned to the vlan interface.

yeah thats exactly what i've found the documentation is non-existent or still refers to the p5 SEA methods.
I was trying to avoid the support call because that can be a painful experience.

based on my experience, which is limited, with the IVE impletmentations,
I can see where that may have issues. We aren't using VLAN tagging but
we spent a couple of days going through what limited documentation is
available just to get aggregation working. Sorry I can't be more help.
You may want to engage support on this one. I haven't met very many
people that really understand IVE's restrictions for different
implementations, and, I couldn't find any resource that really explained
the how-to of each scenario.

What I'm meaning is
LPAR 1 off of T1 in VLAN 1
LAPR 2 off of T1 in VLAN 2
LPAR 3 off of T1 in VLAN 1
LPAR 4 off of T1 in VLAN 6
So T1 is trunked to handle multiple VLANs.
Mills, John T wrote:I'm not sure I understand the middle sentence, but, we had an initialports
issue with trunking on LHEA. The resolution was to allocate both
and EtherChannel all clients that use those ports. Basically:on
Lpar1 T1,T2 2 port agg Lpar1 T1,T2 2 port agg
Lpar2 T1 Lpar2 T1,T2 2 port agg
Lapr3 T2 Lpar3 T1,T2 2 port agg
We haven't had a problem since. Also the factoy enabled promiscuousthe "serial number" lpar. We usually just ignore that one andsometimesuse them in an emegency situation for a full system service partition.Of
We had to disable the setting to just get started.

Subject: p550 LHEA and port trunking
I have a new p550 that uses LHEA (logical host ethernet adapter) for network connectivity.
I'm having an issue where I can not trunk to a physical port on the adapter to use different VLANs on different LPARs.
The switches are cisco and we are using .1q trunking. Has anyonethis or have any ideas. What happens is the LPAR has no connectivitytoanything inside or outside its subnet.
