Configuring Packet Capture Length

The packet capture length is the length of each packet captured by the AntiDDoS. Each AntiDDoS is configured with only one packet capture length, which applies to all capture tasks on the AntiDDoS.

Prerequisites

You have configured the Encryption Key of Packet Capture.

Choose Defense > Network Settings > Collectors.
Create the Collector, and configure
Encryption Key
.

Before configuring a packet capture task, configure a key for encrypting packet capture logs. The AntiDDoS uses this key to encrypt packet capture logs and then sends the logs to the ATIC management center. The ATIC management center uses this key to decrypt the logs and process them. If the key is deleted, no packet is captured even though a packet capture task has been configured.

NOTE:

The passwords must meet the minimum complexity requirement. That is, the passwords must contain at least three of the following, including upper-case letters (A to Z), lower-case letters (a to z), digits (0 to 9), and special characters (such as !, #, $, and %). You must change the passwords periodically.

Procedure

Choose Defense > Policy Settings > Global Policy
Click in the Operation column.
Choose one method from Configure Packet Capture Length.
NOTE:
After you select All in the packet capture feature, every complete data packet that matches the packet capture policy is captured, which occupies certain system resources. Therefore, you are advised to enable this function only in locating attacks of unknown types.
Click Deploy to deliver configurations to the device.
In the Deploy dialog box, display the deployment progress. After the deployment is complete, the dialog box closes automatically.
- If the deployment succeeds, Deployment of the Zone is displayed as Deploy Succeed.
- If the deployment fails, Deployment of the device is displayed as Deploy Failed.

Follow-up Procedure

Choose Defense > Policy Settings > Global Policy, select the check box of the device and click to save configurations to the configuration file of the device to avoid data loss.
