    Addressed Issues in Prisma SD-WAN ION Device Release 6.5.3

    The following table lists the issues addressed in Prisma SD-WAN ION device release 6.5.3.
    Issue IDDescription
    CGSDW-36948Resolved an issue on Gen2 platforms with UFC ports where static route-reachability probes failed due to an internal binding error.
    CGSDW-36431Resolved an issue where an invalid configuration from the controller caused the fwmgr process to restart and prevented backup ION devices from connecting to the controller.
    CGSDW-36419Resolved an issue where the rtr_mgr_api process unexpectedly restarted due to memory corruption within the Python regex library.
    CGSDW-36417Resolved an issue where the firewall dropped TCP packets when out-of-order packets exceeded the threshold and buffering reached per-flow or per-thread limits. The firewall now forwards these packets instead of dropping them.
    CGSDW-36302Resolved an issue on ION 3200 appliances in L2 mode where low packet buffer (mbuf) allocation caused system timeouts. This occurred because the buffer reservation logic for virtual interfaces exceeded available memory when supporting multiple Switch Virtual Interfaces (SVI).
    CGSDW-36098Resolved an issue where hard or soft resets for BGP peers failed when initiated from the controller web interface due to stale entries.
    CGSDW-36058Resolved an issue where TACACS authentication failed due to a memory leak in the authentication process (authd). This leak occurred over time based on the volume of authentication requests and prevented users from logging in.
    CGSDW-35936Resolved an issue in data center clusters where dual ION devices incorrectly continued to advertise prefixes from a secondary branch site after the primary branch site route was restored. This occurred because routes learned from the secondary branch were not withdrawn following primary path recovery.
    CGSDW-35596Resolved an issue on Data Center ION (DC ION) devices where internal routing rules were not correctly programmed after toggling the site state. When the site state changed from disabled to active or control, interface-based rules failed to recreate, preventing proper traffic handling across interfaces.
    CGSDW-33885Resolved an issue where successful SSH authentications incorrectly generated authentication failure logs. This was caused by an internal configuration setting that triggered false-positive error messages during the login process.
    CGSDW-31501Resolved an issue on ION 3200 series devices where the default gateway was not configured for ISP interfaces following an unclaim operation and subsequent configuration updates. This was caused by an internal logic error that failed to correctly process interface settings when the device role was not explicitly defined.
    CGSDW-30788Resolved an issue where multiple processes restarted and disrupted production traffic. This occurred when LAN asymmetry and Zone-Based Firewall (ZBFW) caused blocked flows to reach the PP_2 process.
    CGSDW-30052Resolved an issue where ION devices stopped responding to ARP requests on WAN interfaces. This was caused by an internal transmit queue becoming unresponsive after encountering a malformed packet, which prevented the processing of subsequent network traffic.
    CGSDW-16922Resolved an issue where ION devices unexpectedly crashed during a reboot or software upgrade due to a startup timing conflict. The service initialization logic has been updated to ensure the data plane is fully ready before processing commands.
    CGSDW-35622Resolved an issue where data traffic incorrectly egressed the DC ION device via the controller port.
    CGSDW-35111Resolved an issue where the RX/TX statistics displayed in the UI sometimes showed values higher than the maximum interface link speed.
    CGSDW-33282Resolved an issue where the system failed to automatically archive the /log/syslog directory following a process crash or device reboot.
    CGSDW-32858Resolved an issue where multi-hop BGP learnt routes on the DC device were not re-distributed to the Branch. This omission occurred because the system failed to correctly resolve the BGP next-hop via the default route.
    CGSDW-32105Resolved an issue where the interface address flapped, which caused instability in BGP, VPN, and HA connections.
    CGSDW-30565Resolved an issue where traffic was lost after a VPN switchover was triggered on the Spoke device. This occurred because the system failed to update the bridge vector with the new WAN interface details, causing traffic to be forwarded to the old, down VPN interface.
    CGSDW-30073Resolved an issue that caused the event_forward process to repeatedly restart on the ION device. This occurred due to a technical incompatibility in the system's priority queue handling following the Python upgrade.
    CGSDW-30067Resolved an issue that caused the dpdk-ctrl-port process to crash on the ION device operating in L2 mode.

    Addressed Issues in Prisma SD-WAN ION Device Release 6.5.1

    The following table lists the issues addressed in Prisma SD-WAN ION device release 6.5.1.
    Issue IDDescription
    CGSDW-29207Resolved an issue where the ION device incorrectly created application probes for WAN-to-WAN initiation failure flows. The system wrongly populated the probe's destination port using the flow's source port, resulting in the creation of many unnecessary probes for the same destination.
    CGSDW-28697Resolved an issue where the ION device incorrectly created two flows instead of one for traffic in scenarios involving route leaking with a Service Link (SL) and a Custom Virtual Routing and Forwarding (VRF).
    CGSDW-28458Resolved an issue where the ION device stopped passing traffic after raising the DEVICESW_CONCURRENT_FLOWLIMIT_EXCEEDED alarm.
    CGSDW-28329Resolved an issue where the backup-DC ION device incorrectly advertised branch prefixes when a core-facing BGP peer flapped.
    CGSDW-28214Resolved an issue where the standalone interface on the standby ION device went down when the active ION device was powered down.
    CGSDW-28187Resolved an issue where the ION device failed to initiate a SYN request over TCP port 179 to establish BGP with its peer after a reboot.
    CGSDW-28049Resolved an issue where the dump-support and dump-support all commands failed to capture the system logs and core dumps on the ION device.
    CGSDW-28036Resolved an issue where VPN OIDs changed with every polling request on the ION device.
    CGSDW-27728Resolved an issue that caused the fp-rte process to crash on the ION device, leading to an immediate High Availability (HA) failover.
    CGSDW-27588Resolved an issue where the Performance Policy Alarm failed to display the complete WAN interface information. This occurred because the ION device did not translate the WAN interface ID to its corresponding name when the name was initially empty.
    CGSDW-27542Resolved an issue where BGP failed to establish connectivity after the ION device transitioned to the High Availability (HA) active state. This occurred because the ION device incorrectly processed BGP configuration messages while in standby mode.
    CGSDW-27498Resolved an issue where the default route was missing on subinterfaces after the ION device rebooted. This issue affected virtual interfaces created on specific ports where subinterfaces were then configured on those virtual ports.
    CGSDW-27359Resolved an issue where application and TCPP global statistics were missing when a high number of application thresholds (50 or more) were configured. This scale issue occurred because the ION device failed to send statistics in a timely manner, causing the data to arrive out of order and resulting in the loss of both types of statistics.
    CGSDW-25254Resolved an issue where a memory buffer (mbuffer) leak was observed in Branch Gateway ION devices. When memory became exhausted, this leak caused VPN disconnections and the loss of connection to the controller.
    CGSDW-23739Resolved an issue where the ION device continued to generate and observe application probe flows even after the feature was disabled in the user interface. The fix ensures that flow observation and generation cease immediately after the feature is disabled.
    CGSDW-22911Resolved an issue that caused the fp-rte process to crash on the ION device when QoS was enabled for UDP traffic on a WAN-to-LAN flow. This failure was due to a timing issue that occurred when one of multiple existing VPNs flapped. The crash happened because packets in the ingress QoS pipeline incorrectly referenced a deallocated structure. The fix ensures that the QoS pipeline safely handles VPN state changes.
    CGSDW-30550Resolved an issue where a memory leak or continuous memory increase was observed in the fp-rte process
    CGSDW-29207Resolved an issue for WAN to WAN flow failures in Branch Gateway sites, where the app probe entries were being created with the flow's source port as the probe destination port.
    CGSDW-28697Resolved an issue where two flows were being created for a VPN tunnel with global VRF configured.
    CGSDW-28458Resolved an issue where the ION Device was not passing traffic after the DEVICESW_CONCURRENT_FLOWLIMIT_EXCEEDED alarm was generated.
    CGSDW-28329Resolved an issue where a backup DC ION device continued to advertise branch prefixes after a BGP reset.
    CGSDW-28214Resolved an issue wherein a stand-alone interface of the backup ION device connected via a bypass configuration to the active ION went down, when the active ION device was powered down.
    CGSDW-28187Resolved an issue where BGP was not being reestablished after a device reboot.
    CGSDW-28049Resolved an issue where the dump-support output and dump-support all commands did not capture the syslogs in the ION 9000 platform, if there was a soft link.
    CGSDW-28036Resolved an issue where the VPN Object Identifiers were changing for every polling request.
    CGSDW-27827Resolved an issue where event logs and SNMP alerts were triggered opposite to the action on the web interface.
    CGSDW-27728Resolved an issue where the fp-rte process was crashing on an upgrade to software version 6.3.4.
    CGSDW-27697Resolved an issue where statistics were not displayed due to memory issues.
    CGSDW-27588Resolved an issue where the WAN Interface was displaying the ID instead of the name on the web interface.
    CGSDW-27542Resolved an issue where the BGP was going down on the active ION device after an HA switchover after upgrading the software version to 6.3.4.
    CGSDW-27498Resolved an issue where the default route was missing on sub-interfaces after a device reboot.
    CGSDW-27241After enabling logs for the flow controller, the logs are not rolling over correctly, thus using up all the space in the log directory.
    CGSDW-27359Resolved an issue of missing application statistics, when a higher number of application performance SLA thresholds were configured.
    CGSDW-25658Resolved an issue of the fp-rte process restarting which was leading to HA failover and instability of the device.
    CGSDW-25152Resolved an issue where custom L3/L4 applications were not being detected properly for UDP traffic after an HA switchover.
    CGSDW-23881Resolved an issue for a potential DDoS vulnerability wherein the flows now time out correctly.
    CGSDW-19357When a DC ION receives routes for a /32 prefix from both the underlay and overlay, the DC ION tries to split the route and thus the BGP route selection process fails.
    CGSDW-19117Resolved an issue where the LQM session wasn't get reestablished after a vpnd process crash.
