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.

I’m thinking 2 aggregations that fail between each other Here’s what I use to check our systems. How to find 1 day old file on Windows for Active Perl.
Etherchannl special hardware is required to use Network Interface Backup, but the backup adapter must be connected to a separate switch for maximum reliability. Originally Posted by homeyjoe. How to active this network adapter?
Thanks, below also good reading. The Link Aggregation status is a diagnostic value and does not affect the AIX side of the configuration. Little, if any, configuration of switch required to form aggregation.
Etherchanenl August 10, at 6: The Available Network Adapters displays all Ethernet adapters. If an adapter fails, the packets are automatically sent on the next available adapter without disruption to existing user connections. I have a server with aaix network interfaces. We Unix Admins appreciate it: If possible please upload screen shots or videos any other new Tech in power series: The adapters making up the Primary Channel connect to the same switch and adapters making up Secondary Channel connect to another.
Can I have a 4 nic primary channel and a 4 port backup channel? In EtherChannel backup, coming back to the main EtherChannel from the backup adapter is not counted as a failover.
How do I calculate total number of active and non active hosts? In a usual etherchannel configuration you have 1 primary and 1 standby backup adapter. Change the Enable Jumbo Frames value to yes and press Enter.
Anonymous November 8, at Mac address – what is line command to find and active new card. Some initial setup of the switch may be required. 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. Posted by anAND at Traffic is distributed across the etherchqnnel in either the standard way where the adapter over which the packets are sent is chosen depending on an algorithm or on a round-robin basis where packets are sent evenly across all adapters.
This mode is aiz typical choice for two hosts connected back-to-back without an intervening switch. We want to configure an etherchannel with four ethernet adapters.
Aids detection for failover to backup adapter. Still understanding problem for me To debug any aggregation problems, it is best to verify the switch’s configuration. Fayez Mohammed March 12, at 9: Outgoing traffic is spread evenly across all the adapter ports in the EtherChannel.
Thanks for all help etherchanjel advance. Rahul Aggarwal June 5, at 9: You first need to detach this interface if you want to use it. I searched a little bit for this and found this forum, where soemeone wants to do the same: Incoming traffic is distributed in accordance to the switch configuration and is not controlled by the EtherChannel operation mode.
As per my understanding if one of the interfaces of etherchannel goes down the other one should be keep the interface up and available!
For EtherChannel to work correctly, the link polling mechanism that periodically verifies the status of the link must be enabled on each adapter before the EtherChannel is created.
EtherChannel is a trademark registered by Cisco Systems and is generally called multi-port trunking or link aggregation.
Up ServerA entstat -d en3 grep -i link entstat: I was confused and didn’t understand clearly the differences between link aggregation and etherchannel until now. I don’t have an scenario to try so it’s difficult for my to teherchannel the best option between them. If all adapters in the EtherChannel fail, the backup adapter is used to send and receive all traffic. Network Interface Backup, a mode of operation available for EtherChannel, protects against a single point of Ethernet network failure.
Network Interface Backup provides detection and failover with no disruption to user connections. Hi, this is written by IBM: I am confused also I remember I did it before and it works.
This does not mean that such configurations will not work. The backup and Ethechannel adapters must be attached to different network switches, which must be interconnected for etherchannek setup to work properly.
