(Optional) Configuring SNMPv2c Attack Defense


To improve SNMPv2c connection security, the device supports the IP address blacklist function. If an SNMPv2c 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 blacklist is enabled.

    By default, the IP address blacklist is enabled.

  3. Run commit

    The configuration is committed.
