Understanding UTM Support for Active/Active Chassis Cluster


UTM requires a license for each device in the chassis cluster setup. For information about how to purchase a software license, contact your Juniper Networks sales representative at

All the following UTM features are supported in active/active chassis cluster:

  • Antispam filtering

  • Enhanced Web-filtering

  • Content Filtering

  • Local Web-filtering

  • Sophos anti-virus scanning

  • Websense Redirect Web-filtering

UTM supports active/active chassis cluster configuration from Junos OS Release 19.4R1 onwards. Active/Active cluster is a cluster where interfaces can be active on both cluster nodes at the same time. This is the case when there are more than one data-plane redundancy-groups, i.e. redundancy-groups 1 and higher or when local (non-reth) interfaces are used on the cluster nodes.
