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.
Procedure
- Run system-view
The system view is displayed.
- Perform either of the following configurations as required.
- Run port-tx-enabling-delay port-tx-delay-time
The signal sending delay function is enabled, and the signal sending delay is configured.
- 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.
