I found the problem...
I was configuring the controllers to act as a load balancing etherchannel controller. This normally would not be a problem, but I had each NIC connected to a different switch.
I removed the Etherchannel adapter and recreated a new one with a primary/backup failover configuration and it is working fine now.

I have 1 AIX server, 4 dual ported fiber attached ethernet cards and 4 VLANS coming in. Is it possible to present those 8 ports as 1 IP address using etherchannel? Thanks. (5 Replies)

I have a server with multiple network interfaces. 2 of these interfaces, lets say en2 and en6 make up an etherchannel interface, which let's say en8.
when I run the command
lsattr -El ent8
I can see the designated primary and backup interfaces as ent6 and ent2, in the given order. But... (10 Replies)

4 x 1Gbit port ethernet adapter is dedicated to vios. 8023ad etherchannel is created using those 4 ports. Etherchannel adapter is shared to lpars using SEA.

AE(4) BSD Kernel Interfaces Manual AE(4)
NAME
ae -- Attansic/Atheros L2 FastEthernet controller driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device miibus
device ae
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
if_ae_load="YES"
DESCRIPTION
The ae device driver provides support for Attansic/Atheros L2 PCIe FastEthernet controllers.
The controller supports hardware Ethernet checksum processing, hardware VLAN tag stripping/insertion and an interrupt moderation mechanism.
Attansic L2 also features a 64-bit multicast hash filter.
The ae driver supports the following media types:
autoselect Enable autoselection of the media type and options. The user can manually override the autoselected mode by adding media
options to rc.conf(5).
10baseT/UTP Select 10Mbps operation.
100baseTX Set 100Mbps (FastEthernet) operation.
The ae driver provides support for the following media options:
full-duplex Force full duplex operation.
half-duplex Force half duplex operation.
For more information on configuring this device, see ifconfig(8).
HARDWARE
The ae driver supports Attansic/Atheros L2 PCIe FastEthernet controllers, and is known to support the following hardware:
o ASUS EeePC 701
o ASUS EeePC 900
Other hardware may or may not work with this driver.
LOADER TUNABLES
Tunables can be set at the loader(8) prompt before booting the kernel or stored in loader.conf(5).
hw.ae.msi_disable
This tunable disables MSI support on the Ethernet hardware. The default value is 0.
SYSCTL VARIABLES
The ae driver collects a number of useful MAC counter during the work. The statistics is available via the dev.ae.%d.stats sysctl(8) tree,
where %d corresponds to the controller number.
DIAGNOSTICS
ae%d: watchdog timeout. The device has stopped responding to the network, or there is a problem with the network connection (cable).
ae%d: reset timeout. The card reset operation has been timed out.
ae%d: Generating random ethernet address. No valid Ethernet address was found in the controller NVRAM and registers. Random locally admin-
istered address with ASUS OUI identifier will be used instead.
SEE ALSO
altq(4), arp(4), miibus(4), netintro(4), ng_ether(4), vlan(4), ifconfig(8)
HISTORY
The ae driver and this manual page was written by Stanislav Sedov <stas@FreeBSD.org>. It first appeared in FreeBSD 7.1.
BUGS
The Attansic L2 FastEthernet controller supports DMA but does not use a descriptor based transfer mechanism via scatter-gather DMA. Thus the
data should be copied to/from the controller memory on each transmit/receive. Furthermore, a lot of data alignment restrictions apply. This
may introduce a high CPU load on systems with heavy network activity. Luckily enough this should not be a problem on modern hardware as L2
does not support speeds faster than 100Mbps.
