[SRX] UTM support in HA for SRX

0

0

Article ID: KB17492 KB Last Updated: 05 Jun 2020Version: 7.0
Summary:

This article provides information about support for Universal Threat Management (UTM) while using SRX chassis clusters.

 

Symptoms:

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 master 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.

 

Solution:

Chassis cluster deployments support Universal Threat Management (UTM) with Active/Passive and Active/Active setup modes in the following Junos OS versions: 

HA Deployment type UTM Feature Supported Junos version
Active/Passive ALL All current
Active/Active Content Filtering All current
URL Filtering -  Redirect All current
URL Filtering - Local All current
URL Filtering - Enhanced 19.4R1
Anti-Spam All current
Anti-Virus (Sophos-engine) 19.4R1
Anti-Virus (Express engine) 11.4 until 12.3X48
Anti-Virus - (Kaspersky engine) 11.4 until 12.3X48
 

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.
