(Optional) Configuring SNMPv3 Attack Defense

(Optional) Configuring SNMPv3 Attack Defense


When a device is configured to communicate with an NMS (AAA local user) through SNMPv3, the device supports the IP address blacklist function to protect the network against attacks. This function improves security of SNMPv3 connections.

IP address blacklist: If an SNMPv3 user fails to access the network, the IP address of this user is added to the blacklist and locked for a certain period of time. The period is 8s for the first lock, 16s for the second lock, 32s for the third lock, and 300s for the fourth lock. The user is not allowed to connect to the network using this IP address within the locking period.


  1. Run system-view

    The system view is displayed.

  2. Run undo snmp-agent blacklist ip-block disable

    The IP address is added to the blacklist.

    By default, the IP address of the user who fails to connect to the device through SNMPv3 is added to blacklist.

  3. Run commit

    The configuration is committed.
