Checking Security Risks

Checking Security Risks

This chapter describes how to check security risks in the system so that you can clear them timely.


Different protocols have different security levels, and some of them may bring security risks. Run the display security risk command to identify security risks in the system. Then clear the security risks according to the repair suggestions in the command output. For example, if SNMPv1 is configured on a device, the display security risk command output will advise you to use SNMPv3 to improve system security.


  • Run the display security risk [ feature feature-name ] [ level { high | medium | low } ] command to show security risks and handling suggestions.


    The security risks that are displayed vary with user levels. The system administrators can view all security risks in the system. Other users can only view the security risks matching their levels.
