title: Scale up the ASE cluster
description: Scale up the ASE cluster by adding nodes to an active cluster without disrupting traffic. To add a new cluster node, enter the peer_node IP address or hostname in the cluster.conf file of the ASE node and then start the ASE node. The new node will synchronize configuration and cookie data from the peer nodes. After loading, it will become part of the cluster. For 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.

# Scale up the ASE cluster

Scale up the ASE cluster by adding nodes to an active cluster without disrupting traffic. To add a new cluster node, enter the `peer_node` IP address or hostname in the `cluster.conf` file of the ASE node and then [start the ASE node](pingintelligence_starting_stopping_ase.html). The new node will synchronize configuration and cookie data from the peer nodes. After loading, it will become part of the cluster. For 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.
