+Advances the cluster config epoch.
+
+The `CLUSTER BUMPEPOCH` command triggers an increment to the cluster's config
+epoch from the connected node. The epoch will be incremented if the node's
+config epoch is zero, or if it is less than the cluster's greatest epoch.
+
+**Note:** config epoch management is performed internally by the cluster, and
+relies on obtaining a consensus of nodes. The `CLUSTER BUMPEPOCH` attempts to
+increment the config epoch **WITHOUT** getting the consensus, so using it may
+violate the "last failover wins" rule. Use it with caution.
+
+@return
+
+@simple-string-reply: `BUMPED` if the epoch was incremented, or `STILL` if the
+node already has the greatest config epoch in the cluster.
