Adapter additions, removals, or changes in an EtherChannel or Link Aggregation

All times are GMT Anonymous August 10, at 6: I searched a little bit for this and found this forum, where soemeone wants to do the same: You first need to detach this interface if you want to etherchanjel it. The traditional AIX behavior. In AIX 5L with and later, enabling the link polling mechanism is not necessary.

Mixing adapters of different speeds in the same EtherChannel, even if one of them is operating as the backup adapter, is not officially supported. The link poller will be started automatically. We had these cris-crossed and etherchannrl never was Aggregated. Thanks for providing ethrchannel details and commands. Find all posts by zxmaus. I have one question. Anonymous December 30, at 9: If all links in etherchannnel EtherChanel are attached to a single switch and if the switch is unplugged or fails, the entire EtherChannel is lost.

When you have Link agg. The interface is defined on the EtherChannel. You should consult the documentation for your switch to determine what initial steps, if any, must be performed to enable LACP in the switch. Little, if any, configuration of switch required to form aggregation.

I am thinking that way I will not have a problem with link aggregation of two etherchannfl which probably will resolve the LACP issue on the Cisco side and I will still have some redundancy because other port will be the backup port, in case the something happens to switch or port.

Abdul Rauf Abidi September 10, at Network Interface Backup provides detection and failover with no disruption to user connections. If your Ethernet switch device has this function, you can exploit the support provided in AIX.

I suggest also to read this, where are etherchanndl tips how to increase bandwidth: Anonymous Ethercjannel 21, at 7: This mode is the typical choice for two hosts connected back-to-back without an intervening switch.

This can be seen: Ideally, ent0 and ent1 are connected to the same EtherChannel-enabled switch, and ent2 is connected to a different switch. 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.

Etherchannrl you suggest a solution? We want to configure an etherchannel with four ethernet adapters. On AIX with “smitty etherchannel”, in the same menu, depending how the fields are filled out, 2 distinctly separate functioning devices can be created. So what I want to do is remove the one adapter port from the EtherChannel ent0 or ent1 then add it back to EtherChannel as a backup adapter.

EtherChannel

You must manually configure this switch to treat the ports that belong to the EtherChannel as an aggregated link. Any thoughts on an alternate way to list MAC for it? In a usual etherchannel configuration you have 1 primary and 1 standby backup adapter. When any link in the EtherChannel is restored, the service is moved back to the EtherChannel. Etherdhannel does not mean that such configurations will not work.

EtherChannel network redundance problem. My co worker Luis scripted this setup-lb ip ent1, ent2 primary. How do I calculate total number of active and non active hosts?

Only failing over from the main channel to the backup is counted. But since I have no control over the network switches, I do not see if a switch had problems and my etherchannel failed over to the backup interface or not and, to my surprise, this happens more often than one might think.

Network Interface Backup, a mode of operation available for EtherChannel, protects against a single point of Ethernet network failure.

Configuring an EtherChannel

So, a 2x10Gb LACP channel, for 1 connection will utilize only 1 adapter at a time, and there is no guarantee that the next connection will be dispatched to the other adapter. For EtherChannel to work correctly, the link polling mechanism that periodically verifies the status of the link must be enabled on each adapter ftherchannel the EtherChannel is created. If you select an Ethernet adapter alx is already being used has an interface definedyou will get an error message. No special hardware is required to use Network Interface Backup, but the backup adapter must be connected to a separate switch for maximum reliability.

The steps to enable the use of IEEE In our environment etherchannel is created in VIOS, but we don’t use lhea in that. Anonymous January 20, at 4: Durham-EMS June 21, at 6: I was confused and didn’t understand clearly the ethefchannel between link aggregation and etherchannel until now.
