# Set nodes to standby mode

When a cluster runs in standby mode, only one node at a time processes traffic. The other running nodes are on standby.

##

Standby nodes monitor the traffic so that they can take over if the active node fails. Only one node at a time is in the online state, and the rest are either in the standby or offline state. When you command an online node to standby, a standby node in the cluster (if there is one) automatically goes online to take over the traffic.
