Description
Specify a redundancy group interface to be monitored for failover and the relative weight of the interface.
For a redundancy group to automatically failover to another node, its interfaces must be monitored. Interface monitoring monitors the physical status of an interface.
When you configure a redundancy group, you can specify a set of interfaces that the redundancy group is to monitor for status (or “health”) of interface to determine whether the interface is up or down. A monitored interface can be a child interface of any of its redundant Ethernet interfaces.
When you configure an interface for a redundancy group to monitor, you assign a weight to the interface. Every redundancy group has a threshold tolerance value initially set to 255. When an interface monitored by a redundancy group becomes unavailable, its weight is subtracted from the redundancy group's threshold. When a redundancy group's threshold reaches 0, the redundancy group fails over to the other node in the cluster.
Options
| name | Name of the interface to monitor |
| weight | Weight assigned to this interface that influences failover
