Disable the Device from Responding to TC packets

Disable the Device from Responding to TC packets


After the device on a ring network is disabled from responding to TC packets, the device will not age or delete ARP entries after receiving TC packets, reducing resource consumptions caused by frequent ARP entry updates and minimizing adverse impacts on user services.


  1. Run system-view

    The system view is displayed.

  2. Run arp topology-change disable

    The device is disabled from responding to TC packets.

    By default, the device responds to TC packets, so the device ages or deletes ARP entries after receiving a TC packet.

  3. Run commit

    The configuration is committed.
