Application Layer Gateways (ALGs)

  • On SRX Series devices with chassis cluster, when the H.323 ALG is enabled and having the H.323 traffic passing through the device, an RG1 failover might generate core files and FPC0 restart on both the nodes. PR1516612

Chassis Clustering

  • On SRX4100 and SRX4200 devices with chassis cluster in transparent mode, when a failover occurs for RG1, the interface on the new secondary node is getting flapped as expected to let the switch update its MAC address table. PR1490291

  • IP monitoring on SRX4100 and SRX4200 device might fail in the rare event that a chassis internal connection between Routing Engine and Packet Forwarding Engine is temporarily down after RG0 failover. PR1502462

Flow-Based and Packet-Based Processing

  • On SRX Series devices, when the GRE or IP-IP tunnel is used, if some interface change events happen (such as, interface flapping), traffic drop might be seen. PR1500091

  • On SRX Series devices, a node of chassis cluster might stop passing traffic. The traffic forwarding can be restored by a manual failover to node 1. PR1528898

Interfaces and Chassis

  • On SRX320, SRX340, SRX345, SRX380, and SRX550M devices with an LTE Mini-Physical Interface Module (Mini-PIM), the LTE connection might drop and fail to auto recover because of firmware issue. PR1520879
