If different types of adapters are used in the same EtherChannel, the capabilities reported to the interface layer are those supported by all of the adapters (for example, if all but one adapter supports the use of private segments, the EtherChannel will state it does not support private segments; if all adapters do support large send, the channel will state it supports large send).

Important: Mixing adapters of different speeds in the same EtherChannel, even if one of them is operating as the backup adapter, is not supported. This does not mean that such configurations will not work. The EtherChannel driver makes every reasonable attempt to work even in a …

When operating in this mode, only one adapter is active at any given time. If the active adapter fails, another adapter in the EtherChannel will be used for all traffic. When operating in Network Interface Backup mode, it is not necessary to connect to EtherChannel-enabled switches.

If you are planning to use EtherChannel backup, do not select the adapter that you plan to use for the backup at this point. Note: The Available Network Adapters displays all Ethernet adapters. If you select an Ethernet adapter that is already being used (has an interface defined), you will get an error message.

This behavior will lead to total etherchannel failure when backup goes down while primary link is up. Problem conclusion Etherchannel driver code is fixed to allow force failover from backup to primary.

EtherChannel Backup allows an aggregated adapter to have a backup. If all adapters that compose the aggregation fail, then communication is switched to the backup adapter until any adapter in the main channel recovers.

Sep 18, 2012 · When adding an adapter to an EtherChannel at runtime, be sure that it supports at least the same capabilities as the other adapters already in the EtherChannel. If you attempt to add an adapter that does not support all the capabilities the EtherChannel supports, the addition will fail.
