Disabling a Device from Packetizing ND Packets and ND Miss Messages

Disabling a Device from Packetizing ND Packets and ND Miss Messages

Context

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

If a user sends an IPv6 packet with an irresolvable destination IPv6 address to the device (that is, if the device has a route to the destination IPv6 address of the IPv6 packet but has no ND entry matching the next hop of the route), the device generates an ND Miss message. By default, the device packs ND Miss messages and sends the package to the CPU. This improves the efficiency of processing the ND Miss messages.

When the ND Miss message packetizes function is enabled, the X series cards cannot reply to ICMPv6 host unreachable packets. To enable these cards to reply to ICMPv6 host unreachable packets, you can disable the ND Miss message packing function.

Procedure

  • Disable a device from packetizing ND packets

    1. Run system-view

      The system view is displayed.

    2. Run nd message-cache disable

      The device is disabled from packetizing ND packets.

      By default, devices are enabled to packetize ND packets.

  • Disable a device from packetizing ND Miss messages

    1. Run system-view

      The system view is displayed.

    2. Run nd-miss message-cache disable

      The ND Miss message packing function is disabled.

      By default, the ND Miss message packing function is enabled.

      NOTE:

      Only the X series cards support disabling packetizing ND Miss messages.

Verifying the Configuration

  • Run the display current-configuration | include nd message-cache command to check the configuration of the ND packets packetizing function.

  • Run the display current-configuration | include nd-miss message-cache command to check the configuration of the ND Miss message packing function.
