Configuring the Alarm Function for Potential ARP Attacks

Configuring the Alarm Function for Potential ARP Attacks

Context

To allow the administrator to learn the ARP running status in real time, define potential attacks, and take measures, the device provides the alarm function for potential ARP attacks. This function records exceptions of ARP running in real time. To avoid excessive alarms when ARP attacks occur, reduce the alarm quantity by setting a proper interval for sending alarms.

NOTE:
The configuration takes effect only on the following alarms:
  • SECE_1.3.6.1.4.1.2011.5.25.165.2.2.2.4 hwARPSDaiDropALarm
  • SECE_1.3.6.1.4.1.2011.5.25.165.2.2.2.5 hwARPGlobleSpeedLimitALarm
  • SECE_1.3.6.1.4.1.2011.5.25.165.2.2.2.8 hwARPMissGlobleSpeedLimitALarm
  • SECE_1.3.6.1.4.1.2011.5.25.165.2.2.2.3 hwARPSPacketCheck
  • SECE_1.3.6.1.4.1.2011.5.25.165.2.2.2.1 hwARPSGatewayConflict
  • SECE_1.3.6.1.4.1.2011.5.25.165.2.2.2.2 hwARPSEntryCheck

Procedure

  1. Run the system-view command to enter the system view.
  2. Run the arp anti-attack log-trap-timer time command to set the interval for sending ARP alarms.

    The default interval for sending alarms is 0, indicating that the device does not send ARP alarms.
