High Availability (HA) and Resiliency

  • On EX9200 Virtual Chassis, in a rare scenario, GRES might not reach the ready state and might fail to start, because the Routing Engine does not receive the state ack message from the Packet Forwarding Engine after performing GRES. This is a timing issue. It might also stop Routing Engine resource releasing and then cause resource exhausting. Reboot the system if this problem occurs. PR1236882

Network Management

  • SNMP queries to retrieve jnxRpmResSumPercentLost will return the RPM/TWAMP probe loss percentage as an integer value whereas the precise value (including decimal points) can be retrieved through the CLI by using the following commands:

    • show services rpm probe-results

    • show services rpm twamp client probe-results

Platform and Infrastructure

  • On EX9208 switches, a DCD restart might disable the member links in an MC-LAG, resulting in traffic loss. PR1229001

Port Security

  • On an EX9200-6QS line card, storm control might not work for multicast traffic. PR1191611
