525 High availability and load balancing using clusters
Updating interfaces in a cluster configuration
Adding a network interface to a cluster member
You can enable one of the unused interfaces on a cluster member as usage requirements increase. Add
only one new interface at a time.
Adding a network interface in a cluster environment requires changes to the individual cluster
members and to the cluster itself. When you add a new network interface to a cluster, you need to plug
a network cable into the interface on each cluster member.
Prerequisites
None.
