Configuration Updates
Under Manage Network -> Change Management on the web interface of the Network Control Node (NCN), there are two new columns, Traffic Interruption - Expected and Traffic Interruption - Actual. These columns display values that indicate the following for each Site in the Oracle SD-WAN Edge:
Traffic Interruption - Expected: The expected worst traffic interruption time for the Site, based on the difference between the active and staged configurations. For more detail on the impact to each Conduit, refer to APN_traffic_impact.log.
- 0 sec - No service interruption for this Site
- <1 sec - Traffic interruption time will be less than 1 second
- <1 min - Traffic interruption time will be less than 1 minute
- <3 min - Traffic interruption time will be less than 3 minutes (only relevant for software updates, which still require a restart of the Oracle Service)
- Loc Chg Mgt - Package must be applied via that Site's local change management
Traffic Interruption - Actual: The time it took to perform a configuration or software update at the Site. This does not include the time it took for full network convergence during an update. Updates to Sites may occur in parallel.
- N ms/s - Actual traffic interruption time at the Site when the update was performed
- Err - An error occurred when performing the update
From the above, the expected traffic interruption time for the configuration update was 0 seconds (i.e. no expected interruption) for each Site, and that the actual interruption time met this expectation. Certain configuration updates will impact traffic for a period of time. When this is the case, the expected traffic interruption time will show the maximum interruption time that can be expected in the form of <1 sec, <1 min, or <3 min. Prior to activating a staged configuration update, the user can use the expected traffic interruption time for the staged configuration to determine if a maintenance window is required for the update. Please note that an appliance with traffic load may require more time to complete the update process.
