Parameters

top-number: Specifies the number of top ranking IP addresses. The value range is 10 to 100, and the default is 10.

slot slot-number: Specifies an IRF member device by its member ID. If you do not specify a member device, this command displays statistics for IP addresses with the highest hits on the IP reputation list for all member devices.

Usage guidelines

This command displays statistics for IP addresses with the highest hits on the IP reputation list when the top hit ranking feature is enabled.

This command does not display IP addresses with no hits. Therefore, the number of IP addresses in the command output might be less than the value of the top-number argument.

Usage guidelines

After you enable automatic update of the IP reputation signature library, the device periodically accesses the signature database services on the official website to download the latest IP reputation signature library.

Examples

# Enable automatic update of the IP reputation signature library and enter automatic IP reputation signature library update configuration view.

<Sysname> system-view

[Sysname] ip-reputation signature auto-update

[Sysname-ip-reputation-autoupdate]

Syntax

ip-reputation signature auto-update-now

Views

Predefined user roles

network-admin

context-admin

Usage guidelines

After you execute this command, the device immediately starts the automatic update process of the IP reputation signature library no matter whether or not automatic signature library update is enabled. Before overwriting the current signature library file, the device automatically backs it up to the ipreputation_sigpack_curr.dat file in the device storage medium.

You can execute this command anytime you find a new version of signature library on the official website.

Examples

# Trigger an automatic update of the IP reputation signature library manually.

<Sysname> system-view

[Sysname] ip-reputation signature auto-update-now

ip-reputation signature rollback

Use ip-reputation signature rollback to roll back the IP reputation signature library.

Syntax

ip-reputation signature rollback last

Views

Predefined user roles

network-admin

context-admin

Parameters

last: Rolls back the IP reputation signature library to the previous version.

Usage guidelines

If an IP reputation signature library update causes exceptions or a high false alarm rate, you can roll back the IP reputation signature library.

Before performing an IP reputation signature library rollback, the device backs up the current IP reputation signature library as the previous version. For example, the previous library version is V1 and the current library version is V2. If you perform a rollback to the previous version, library version V1 becomes the current version and library version V2 becomes the previous version. If you perform a rollback to the previous version again, the library rolls back to library version V2.

Examples

# Roll back the IP reputation signature library to the previous version.

Parameters

file-path: Specifies the IP reputation signature library file path, a string of 1 to 255 characters.

Usage guidelines

If the device cannot access the signature database services on the official website, use one of the following methods to manually update the IP reputation signature library:

·     Local update—Updates the IP reputation signature library by using a locally stored IP reputation signature library file. To use this method, first obtain the signature library file from the official website and import it to the device.

Store the update file on the master device for successful signature library update.

The following describes the format of the file-path parameter for different update scenarios.

 

Update scenario	Format of file-path	Remarks
The update file is stored in the current working directory.	filename	To display the current working directory, use the pwd command. For information about the pwd command, see file system management in Fundamentals Command Reference.
The update file is stored in a different directory on the same storage medium.	filename	Before configuring the ip-reputation signature update command, use the cd command to open the directory where the file is stored. For information about the cd command, see file system management in Fundamentals Command Reference.
The update file is stored on a different storage medium.	path/filename	Before configuring the ip-reputation signature update command, use the cd command to open the root directory of the storage medium where the file is stored. For information about the cd command, see file system management in Fundamentals Command Reference.

 

·     FTP/TFTP update—Updates the IP reputation signature library by using the file stored on an FTP or TFTP server. The device automatically downloads the signature file from the server before using it to update the signature library.

The following describes the format of the file-path parameter for different update scenarios.

 

Update scenario	Format of file-path	Remarks
The update file is stored on an FTP server.	ftp://username:password@server/filename	The username parameter represents the FTP login username. The password parameter represents the FTP login password. The server parameter represents the IP address or host name of the FTP server. Replace the following special characters in the FTP login username and password with their respective escape characters: ·     Colon (:)—%3A or %3a. ·     At sign (@)—%40. ·     Forward slash (/)—%2F or %2f.
The update file is stored on a TFTP server.	tftp://server/filename	The server parameter represents the IP address or host name of the TFTP server.

 

	NOTE: To update the signature library successfully, make sure the device and the FTP or TFTP server can reach each other. If you specify the FTP or TFTP server by its host name, you must also make sure the device can resolve the host name into an IP address through static or dynamic DNS. For more information about DNS, see Layer 3—IP Services Configuration Guide.

 

Examples

# Manually update the IP reputation signature library by using an IP reputation signature library file stored on a TFTP server.

<Sysname> system-view

[Sysname] ip-reputation signature update tftp://192.168.0.10/ip-1.0.2-en.dat

# Manually update the IP reputation signature library by using an IP reputation signature library file stored on the device. The file is stored in directory cfb0:/dpi/ip-1.0.23-en.dat, and the current working directory is cfa0:.

<Sysname> cd cfb0:/

<Sysname> system-view

attack-category

Use attack-category to configure actions for an attack category.

Use undo attack-category to restore the default.

Syntax

attack-category attack-id { action { deny | permit } | logging { disable | enable } }*

undo attack-category attack-id

Default

No actions are configured for an attack category. Each attack category has its own pre-defined actions.

Parameters

attack-id: Specifies an attack category ID. The value range depends on the IP reputation file and the device model.

action: Specifies an action.

deny: Drops matching packets.

permit: Allows matching packets to pass through.

logging: Sets the logging status for the attack category. When a packet matches the attack category with logging enabled, the device generates logs for the matching events.

disable: Disables logging for the matching events.

enable: Enables logging for the matching events.

Usage guidelines

The command configuration takes effect after you enable IP reputation.

On the IP reputation list, an IP address can belong to multiple attack categories. Each attack category has its own actions.

If an IP address belongs to only one attack category, the device takes the actions in this attack category. If an IP address belongs to multiple attack categories, the device takes an action that has higher priority among all actions in those attack categories. The drop action has higher priority than the permit action.

If logging is enabled for any one of attack categories to which an IP address belongs, the device generates a log when the IP address is matched.

The device supports fast output of IP reputation logs. For more information about fast log output, see fast log output commands in Network Management and Monitoring Command Reference.

Examples

# Set the action to deny for attack category 1 and enable logging for the attack category.

<Sysname> system-view

[Sysname] ip-reputation

[Sysname-ip-reputation] attack-category 1 action deny logging enable
