ARP/4/ARP_SPEED_LIMIT

ARP/4/ARP_SPEED_LIMIT

Message

ARP/4/ARP_SPEED_LIMIT: Packet speed exceeded the configured speed limit. (IfIndex=[IfIndex], SuppressValue=[SupValue], CurrentValue=[CurValue], SuppressType=[SupType], SourceIP=[SrcIp], DestinationIP=[DstIp], VpnInstance name=[VpnName])

Description

The transmit rate of ARP packets or ARP Miss messages exceeded the configured rate limit.

Parameters

Parameter Name Parameter Meaning
IfIndex Interface index
SuppressValue Rate limit of ARP packets or ARP Miss messages
CurrentValue Current transmit rate of ARP packets or ARP Miss messages
SuppressType Type of packets that are suppressed: ARP packets or ARP Miss messages
SourceIp Source IP addresses of ARP packets or ARP Miss messages
DestinationIp Destination IP addresses of ARP packets or ARP Miss messages
VpnInstance name VPN instances that ARP packets or ARP Miss messages belong to

Possible Causes

Cause 1: The transmit rate of ARP packets exceeded the configured rate limit.

Cause 2: The transmit rate of ARP Miss messages exceeded the configured rate limit.

Procedure

  • Cause 1: The transmit rate of ARP packets exceeded the configured rate limit.
    1. Run the display arp anti-attack rate-limit command to check the configured rate limit of ARP packets.
    2. Run the arp anti-attack rate-limit destination-ip maximum maximum command to re-set the rate limit of ARP packets. The value must be greater than the value obtained in Step 1 but less than 65536. Then, check whether the trap is cleared.

      • If the trap is cleared, go to Step 4.
      • If the trap persists, go to Step 3.

    3. Collect trap, log, and configuration information, and contact technical support personnel.
    4. End.
  • Cause 2: The transmit rate of ARP Miss messages exceeded the configured rate limit.
    1. Run the display arp miss anti-attack rate-limit command to check the configured rate limit of ARP Miss messages.
    2. Run the arp miss anti-attack rate-limit source-ip command to re-set the rate limit of ARP Miss messages. The value must be greater than the value obtained in Step 1 but less than 65536. Then, check whether the trap is cleared.

      • If the trap is cleared, go to Step 4.
      • If the trap persists, go to Step 3.

    3. Collect trap, log, and configuration information, and contact technical support personnel.
    4. End.
