Traffic block logs record information about packets that are blocked by UIS. These logs can be used for traffic analysis, attack detection, and network behavior auditing. Additionally, when a communication failure occurs, you can enable traffic bypass to disable all UIS network policies and permit all service traffic to determine whether the failure is caused by network policies.
If you specify an IP address or IP address range to filter traffic block logs, the system matches it against both the source and destination IP addresses of the blocked packets. A traffic block log entry is displayed as long as its source or destination IP address matches the specified criterion.
On the top navigation bar, click Networks, and then select Traffic Block Logs from the left navigation pane. You can view detailed network log information, including source IP address, destination IP address, protocol, time, source MAC address, destination MAC address, and data packet size. For descriptions about these fields, see "Parameters."
