If you have more than one multimode vif, you can use the vif create command to group them by creating a second layer of vif called the second-level vif. Second-level vifs enable you to provide a standby multimode vif in case the primary multimode vif fails.
You can use second-level vifs
on a single storage system
or in an active/active configuration
You cannot use LACP vifs
as second-level vifs
- Guidelines for creating a second-level vif
You can create a single-mode second-level vif over two multimode vifs. The ports of the underlying multimode vifs should be connected to the same switch. If you create a second-level vif over two multimode vifs that are connected to two different switches, you should connect the two switches with an inter-switch link (ISL).
- Creating a second-level vif
You can create a second-level vif by using two multimode vifs. Second-level vifs enable you to provide a standby multimode vif in case the primary multimode vif fails.
- Enabling failover in a second-level vif
In a second-level single-mode vif over two or more multimode vifs, you can enable the vif.failover.link_degraded option for failing over to a multimode vif with higher aggregate bandwidth. The failover happens regardless of whether the currently active vif is favored or not. By default, this option is off.
