Configuration guidelines

Configure this feature when MFF, ARP fast-reply, ARP detection, or ARP snooping is enabled, or
when ARP flood attacks are detected.

Configuration procedure

This task sets a rate limit for ARP packets received on an interface. When the number of ARP
packets that the interface receives within a period exceeds the rate limit, those packets are
discarded.

You can enable sending of notifications to the SNMP module or enable logging for ARP packet rate
limit.

•

If notification sending is enabled, the device sends the highest threshold-crossed ARP packet
rate within the sending interval in a notification to the SNMP module. You must use the

snmp-agent target-host

command to set the notification type and target host. For more

information about notifications, see

Network Management and Monitoring Command

Reference

.

•

If logging for ARP packet rate limit is enabled, the device sends the highest threshold-crossed
ARP packet rate within the sending interval in a log message to the information center. You can
configure the information center module to set the log output rules. For more information about
information center, see

Network Management and Monitoring Configuration Guide

.

To configure ARP packet rate limit:

Step Command

Remarks

1.

Enter system view.

system-view

N/A

2.

(Optional.) Enable
notification sending for ARP
packet rate limit.

snmp-agent trap enable arp

[

rate-limit

]

By default, notification sending for
ARP packet rate limit is disabled.

3.

(Optional.) Enable logging for
ARP packet rate limit.

arp rate-limit log enable

By default, logging for ARP packet
rate limit is disabled.

4.

(Optional.) Set the
notification and log message
sending interval.

arp rate-limit log interval

seconds

By default, the device sends
notifications and log messages at an
interval of 60 seconds.

5.

Enter Layer 2 Ethernet
interface or Layer 2
aggregate interface view.

interface interface-type
interface-number

N/A

6.

Enable ARP packet rate limit
and configure the rate limit.

arp rate-limit

[

pps

]

By default, ARP packet rate limit is
enabled, and the rate limit is 100
pps.

NOTE:

If you enable notification sending and logging for ARP packet rate limit on a Layer 2 aggregate
interface, the features apply to all aggregation member ports.

Configuring source MAC-based ARP attack
detection

This feature checks the number of ARP packets delivered to the CPU. If the number of packets from
the same MAC address within 5 seconds exceeds a threshold, the device adds the MAC address to
