On AIX with “smitty etherchannel”, in the same menu, depending how the fields are filled out, 2 distinctly separate functioning devices can be created. This can. For example, ent0 and ent1 can be aggregated into an EtherChannel adapter called ent3. And interface en3 would then be configured with an.

My co worker Luis scripted this setup-lb ip ent1, ent2 primary. The outgoing adapter path is selected by an algorithm using the combined source and destination TCP or UDP port values.
Configuring an EtherChannel
In this case, you must configure your Ethernet switch to create a etherchanel by aggregating a series of Ethernet ports. Anonymous February 4, at We have an IBM p7 server running a full etherchannep partition, so all ethernet adapters are dedicated to the full system.
In this case, the entstat -d command will always report the aggregation is in the Negotiating state. I just got done with making Link Aggregation work across our environment.
IBM-AIX: How to create EtherChannel in aix?
Hello, I need your help with one of problems which occurs, regarding etherchannel: If all links in one EtherChanel are attached to ftherchannel single switch and if the switch is unplugged or fails, the entire EtherChannel is lost.
Hi, this is written by IBM: After this separation has been done check entstat for link status, speed, duplex, transmit errors, dropped packets, invalid vlan tags Posted by anAND at In this example, all traffic sent over en3 the interface of EtherChannel is sent over ent0 or ent1 by default depending on the packet distribution scheme of EtherChannelwhereas ent2 is idle.
If at any time both ent0 and ent1 fail, all traffic is sent over the backup adapter ent2. Given that we configure both the p7 hardware side and our network switch side correctly, we would expect ethedchannel see greatly increased bandwidth to accommodate the inbound data from multiple TSM clients.
Only failing over from the main channel to the backup is counted.
Are we dreaming, or is this a realistic configuration idea that could improve the service between our TSM server and its clients? Rahul Aggarwal June 5, at 9: Originally Posted by homeyjoe.

When any link in the EtherChannel is restored, the service is moved back to the EtherChannel. Incoming traffic is distributed in accordance to the switch configuration and is not controlled by the EtherChannel operation mode. To configure network interface backup, see Network Interface Backup configuration. I have one question. Ftherchannel Public Profile etherchhannel dukessd.
In AIX 5L with and later, enabling the link polling mechanism is egherchannel necessary. To solve this problem, a backup option is available that keeps the service active when the main EtherChannel fails. If you select an Ethernet adapter that is already being used has an interface definedyou will get an error message.
Anonymous July 15, at 8: This mode is the typical choice for two hosts connected back-to-back without an intervening switch. There are for example 2 primary adapters.
The backup and EtherChannel adapters must be attached to different network switches, which must be interconnected for this setup to work properly. The main benefit of a Link Aggregation is that it has the network bandwidth of all of its adapters. Mixing adapters of different speeds in the same EtherChannel, even if one of them is operating as the backup adapter, is not officially supported.
Once you have established the etherchannel and Aggregation rtherchannel forget to make sure they are indeed Aggregated: Windows Active Network Connection Override. In a usual etherchannel configuration you have 1 primary and 1 standby backup adapter. You should consult the documentation for your switch to determine what initial steps, if any, must be performed to enable LACP in the switch. Still understanding problem for me
