This article provides information about support for Universal Threat Management (UTM) while using SRX chassis clusters.
SRX HA chassis clusters support two modes of setup: Active/Passive and Active/Active.
Active/passive mode: In active/passive mode, transit traffic passes through the primary node while the backup node is used only in the event of a failure. When a failure occurs, the backup device becomes the primary and takes over all forwarding tasks.
Active/active mode: In active/active mode, transit traffic passes through both nodes of the cluster all the time.
Chassis cluster deployments support Universal Threat Management (UTM) with Active/Passive and Active/Active setup modes in the following Junos OS versions:
Example of Active/Passive :
{primary:node1} root@NODE1> show chassis cluster status Cluster ID: 5 Node Priority Status Preempt Manual failover Redundancy group: 0 , Failover count: 1 node0 10 secondary n/a no node1 100 primary no no Redundancy group: 1 , Failover count: 1 node0 10 secondary n/a no node1 100 primary no no
Note : If you are performing a manual failover, make sure to issue the same failover for all redundancy groups.
