Compare AWS Cloud WAN core network policy change set versions

Compare two policy versions against each other using the console. The comparison returns line-by-line changes between the two policies in JSON format with changes highlighted.

To compare policy versions

1. Access the Network Manager console at https://console.aws.amazon.com/networkmanager/home/.

2. Under Connectivity, choose Global Networks.

3. On the Global networks page, choose the global network ID.

4. In the navigation pane, choose Core network, and then choose Policy versions.

5. Under Policy version ID, choose the policy version that you want to compare against another policy.

6. Choose View or apply change set.

7. On the Change set page, choose Compare with LIVE.

8. From the Source and Target dropdown lists, choose the policy versions that you want to compare.

9. (Optional) From the Policy section dropdown list, choose a specific policy section to compare. Options are:

   • All — Compares all policy changes between the two policies. This is the default view.

   • Network configuration — Compares Border Gateway Protocol (BGP), Autonomous System Number (ASN), and core network edge locations.

   • Segments — Compares segment additions, deletions, or modifications.

   • Segment actions — Compares segment sharing and filtering.

   • Attachment policies — Compare how attachments map to segments.

10. Choose Compare.

    The Results of comparison section displays the changes between the two policies. In the following example, the Segments of a current LIVE Source policy are compared against the segment changes to an undeployed Target policy. The comparison shows that a new segment, sandbox, will be added when deploying the Target policy version.

    

11. By default, the changes for each policy display in separate policy windows. To see the results of the comparison line-by-line in a single window, turn the Split toggle off.
