# Scaling up the ASE cluster

Scale up the ASE cluster by adding nodes to an active cluster without disrupting traffic.

## About this task

To add a new cluster node:

## Steps

1. Enter the `peer_node` IP address or hostname in the `cluster.conf` file of the ASE node.

2. Start the ASE node.

   For more information, see [Start the ASE node](pingintelligence_starting_stopping_ase.html).

   ### Example:

   If the IP of the first node is 192.168.20.121 with port 8020, then the `peer_node` parameter would be 192.168.20.121:8020.

   ```
   ; ASE cluster configuration. These configurations apply only when
   ; you have enabled cluster in the api_config file.
   ; Unique cluster ID for each cluster. All the nodes in the same cluster
   ; should have the same cluster ID.
   cluster_id=ase_cluster
   ; Cluster management port.
   cluster_manager_port=8020
   ; Cluster's active nodes. This can be a comma separated list of nodes in
   ; ipv4_address:cluster_manager_port format.
   peer_node=192.168.20.121:8020
   ```

   ### Result:

   The new node will synchronize configuration and cookie data from the peer nodes. After loading, it will become part of the cluster.
