I'm trying to configure Etherchannel on AIX 5.3 and I'm having some problems. I am aggregating both of the onboard NIC's (ent0 and ent1) into a new adapter ent2 for failover reasons obviously. At first I was experiencing a problem where about 50% of all my packets would be dropped. Then after... (4 Replies)
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 one p5 server, no lpar, 2 physical network adapter, bundle as one EtherChannel. The two 2 physical network adapter connect to 2 network switches.
How to make this as a redundancy config?
Current is if one physical network adapter down, the seond one will go through the network. but if... (2 Replies)
I have few AIX servers in my data center, which have their EtherChannel configured to have a fat pipe (active/active) and a nagios server to monitor the server uptimes. Nagios server pings every server in the data center and we have pretty much every known unix flavor in this data center. When... (3 Replies)
Hi,
I have a AIX5.3 P6-520 with 8x1Gb Ethernet ports with possible connections to 2 CISCO 2960 switches.
I can create 8023ad Etherchannels which work correctly with the switches (I have set up for LACP passive and a valid channels)
But can create 2x 8023ad 4Gb Etherchannels with no backups.... (2 Replies)

EN(4) BSD Kernel Interfaces Manual EN(4)NAME
en -- device driver for Midway-based ATM interfaces
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device en
device atm
device utopia
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
if_en_load="YES"
DESCRIPTION
The en device driver supports Midway-based ATM interfaces including the Efficient Networks, Inc. ENI-155 and Adaptec ANA-59x0. Midway is an
AAL5 SAR (Segmentation and Reassembly) chip.
For configuring the card for IP see natmip(4).
The following sysctls are recognized by the driver additionally to those handled by utopia(4):
hw.atm.enX.istats
Contains an array of uint32_t with internal driver statistics.
hw.atm.enX.debug
This is a bit map of debugging options. This variable is only available when the driver is compiled with debugging support.
The driver supports the media options sdh, noscramb and unassigned (see utopia(4)).
DIAGNOSTICS
en0 <Efficient Networks ENI-155p> rev 0 int a irq 5 on pci0:16
en0: ATM midway v0, board IDs 6.0, Utopia (pipelined), 512KB on-board RAM
en0: maximum DMA burst length = 64 bytes
en0: 7 32KB receive buffers, 8 32KB transmit buffers allocated
CAVEATS
The driver extensively uses DMA on PCI. The first generation PCI chipsets do not work or exhibit poor performance.

Chuck Cranor of Washington University implemented en driver in 1996 for NetBSD.
