Enabling the Signal Sending Delay Function

This section describes how to configure the signal sending delay function.

Usage Scenario

After a device is restarted or a board is replaced, if an interface sends signals immediately after initialization before the link completes a switchover or configuration restoration, data loss may occur. To prevent data loss, configure the signal sending delay function.

  • Only physical interfaces can be configured with signal sending delays. Logical interfaces do not support this function.
  • Configuring a signal sending delay does not affect an interface that has sent signals to the peer, and the configuration takes effect after the interface is initialized.


  1. Run system-view

    The system view is displayed.

  2. Perform either of the following configurations as required.
    1. Run interface interface-type interface-number

      The GE, 10GE WAN or 10GE LAN interface view is displayed.

  3. Run port-tx-enabling-delay port-tx-delay-time

    The signal sending delay function is enabled, and the signal sending delay is configured.

  4. Run commit

    The configuration is committed.

Verifying the Configuration

Run the display port-tx-enabling-delay interface { ethernet | gigabitethernet } interface-number command to check information about the signal sending delay configured on the interface.
