WAN Assurance Plugin 3.7 Release Notes

Release 3.7.3​

Release Date: May 25, 2023

New Features​

  • WAN-965 Support sending URL filtering block events to MIST cloud

  • WAN-1751 Support fast updates for interface and peer path status on the MIST UI

Resolved Issues​

  • WAN-1816 Mist agent monitoring fails and mist agent does not restart

    Resolution: The logic to inspect the failure of monitoring agent service was made more robust.

  • WAN-1883 Application summary data is not visible on the MIST UI due to negative values in the data

    Resolution: Handle errors in the application summary document more gracefully by dropping negative value samples.

  • WAN-1914 Packet capture feature on MIST UI is not capturing any packets with reason "Backend could not process"

    Resolution: Handle multiple ongoing PCAPs more gracefully when the process restarts in the middle of a previous capture.

  • WAN-1932 SSR stops sending stats and events but stays connected

    Resolution: Prevent a dead lock condition while sending events when cloud connection transitions from disconnect to connect.

Release 3.7.2​

Release Date: Apr 26, 2023

New Features​

  • WAN-1591 Report the rx/tx bytes and packet information for HA control interfaces

Resolved Issues​

  • WAN-1763 De-duplicate DHCP pool exhausted events

    Resolution: Any duplicated DHCP pool exhausted event generated by the SSR will be dropped from the list of events sent to the MIST cloud.

  • WAN-1796 Prevent a mist-agent crash during initial telemetry push

    Resolution: Gracefully handle the timing of initial config and initial telemetry push to prevent the crash from occurring.

  • WAN-1855 Incorrect neighborhood information displayed in topology details view

    Resolution: Report the correct neighborhood information when the same neighborhood name is used by multiple Hub WAN interfaces.

Release 3.7.1​

Release Date: Mar 31, 2023

Resolved Issues​

  • WAN-1698 Classify custom apps on the hub routers based on the service profile

    Resolution: Any service with RFC1918 address space will be tagged as custom app in the data that hub sends to MIST cloud.

  • WAN-1737 De-duplicate peer path down events

    Resolution: Any duplicated peer path down event generated by the SSR will be dropped from the list of events sent to the MIST cloud.

Release 3.7.0​

Release Date: Mar 03, 2023

New Features​

  • WAN-1440 Report metrics per network interface

For each network-interface the router will report additional metrics such as received packets and bytes as well as transmitted packets and bytes.

  • WAN-1352 Report DHCP server related information

The router will report DHCP pool usage data along with an event when a particular pool is exhausted.

Resolved Issues​

  • WAN-1182 The device port layout takes a long time to populate after initial onboarding

    Resolution: Upon establishing a new connection to the MIST cloud, the device will immediately send all relevant telemetry information to provide most up-to-date information.

  • WAN-1415 Missing port up/down events for non-forwarding ports

    Resolution: The agent will monitor the link status using netlink to report the appropriate runtime state for non-forwarding interfaces.

  • WAN-1420 EP commands are dropped due to no registration

    Resolution: After initial onboarding, the agent will maintain a single active connection to EP terminator to avoid commands being sent on the wrong connection.

  • WAN-1509 Link up/down events and process restart events sometime get lost

    Resolution: The cloud-intel agent will process incoming events in real time and not cache the events for too long to avoid any delays and drops.

  • WAN-1557 SSR reports stale firmware version

    Resolution: The mist-agent will scan and report the latest package version during each stats push.

  • WAN-1564 The data core CPU usage date can sometimes be empty

    Resolution: The mist-agent will ensure that the CPU data is always present in the oc-stats.

  • WAN-1566 Port up/down events are seen for kni254 interface

    Resolution: The mist-agent will filter the port events for KNI interfaces such as kni254.

  • WAN-1632 SSR devices have been sending bytes data as zero, causing large dips

    Resolution: The mist-agent internal collection timers were adjusted to ensure all relevant data is captured in time before pushing the oc-stats.
