The cross-domain traffic analysis feature displays inbound and outbound cross-domain traffic that flows between regions through a TransitRouter. The traffic data is displayed in 1-tuple (source IP), 2-tuple (source IP and destination IP), and 5-tuple (source IP, source port, protocol, destination IP, and destination port) formats to help you analyze cross-domain traffic in your services.
View cross-domain traffic
In the navigation pane on the left, choose .
On the Inter-region Traffic page, select the source region of the cross-domain traffic that you want to view.
Click the 1-tuple, 2-tuple, and 5-tuple tabs. Then, select a time range and specify search conditions to view the trend charts and traffic lists for cross-domain traffic.
You can select a time range and specify search conditions to view traffic details for a specific time, IP address, port, or protocol.

FAQ
Why can't I select an existing TransitRouter in a region from the list when I try to enable cross-domain traffic analysis?
Cross-domain traffic analysis is supported only on the latest version of Enterprise Edition transit routers. If you cannot select an Enterprise Edition transit router in a region, go to the Cloud Enterprise Network console to check whether the transit router is upgraded to the latest version. For more information, see [Upgrade Announcement] Upgrade of VPC connection mode for Enterprise Edition transit routers.
