Disabling a Device from Packetizing ARP Packets and ARP Miss Messages

Disabling a Device from Packetizing ARP Packets and ARP Miss Messages

Context

A device usually packetizes received ARP packets and sends them to the CPU, which improves the ARP packet processing efficiency. However, packetizing causes a delay of a maximum of 100 ms and affects real-time services. To solve the problem, disable the packetizing function on ARP packets.

If a device receives an IP packet containing an irresolvable destination IP address, the device generates ARP Miss messages. By default, the device packetizes ARP Miss messages and sends them to the CPU, improving the efficiency of processing ARP Miss messages. When the device is enabled to packetize ARP Miss messages, the X series cards cannot send ICMP Host Unreachable packets or ICMP Redirect packets. To enable these cards to send ICMP Host Unreachable packets or ICMP Redirect packets, disable the packetizing function on ARP Miss messages.

Procedure

  • Disable a device from packetizing ARP packets

    1. Run system-view

      The system view is displayed.

    2. Run arp message-cache disable

      The device is disabled from packetizing ARP packets.

      By default, devices are enabled to packetize ARP packets.

  • Disable a device from packetizing ARP Miss messages

    1. Run system-view

      The system view is displayed.

    2. Run arp-miss message-cache disable

      The device is disabled from packetizing ARP Miss messages.

      By default, devices are enabled to packetize ARP Miss messages.

      NOTE:

      Only the X series cards support the disabling of the packetizing function on ARP Miss messages.

Verifying the Configuration

Run the display current-configuration | include message-cache command in any view to check the status of the packetizing function on ARP packets and ARP Miss messages.
