Maintaining Smart Link and Monitor Link

Maintaining Smart Link and Monitor Link

Maintaining Smart Link and Monitor Link includes clearing statistics on Flush packets, locking data flows, and manual switching.

Clearing Statistics on Flush Packets

Context

Before collecting statistics on Flush packets in a period of time, clear the existing statistics.

The cleared statistics cannot be restored. Exercise caution when you run the reset command.

Procedure

  1. Run the reset smart-link flush command in the user view to clear statistics on Flush packets.

Configuring the Device to Lock Data Flows

Context

During maintenance, the active link in a Smart Link group needs to be inspected. To prevent the inspection from affecting services, configure the device to forcibly lock data flows to the standby link and switch them back to the active link after the inspection is complete.

If data flows are locked on an interface, they cannot be switched to another interface automatically when the interface fails, causing traffic interruption.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    smart-link group group-id

    The Smart Link group view is displayed.

  3. Run the following commands as required.

    • Run the smart-link lock command to lock data flows on the master interface.
    • Run the smart-link force command to lock data flows on the slave interface.

  4. Run:

    commit

    The configuration is committed.

Configuring Manual Switching of Data Flows

Context

When both the active and standby links are working properly, manual switching of data flows can be configured. The data flows can be switched from the active link to the standby link or from the standby link to the active link.

To implement an active/standby switchover between links, ensure that:

  • The master interface and slave interface exist and are both in Up state.
  • The smart-link { lock | force } command is not used to configure the device to lock data flows.

The smart-link manual switch command can be repeatedly used in the Smart Link group view. Each time you run the command, an active/standby switchover is performed between links. Millisecond-level packet loss will occur during the switchover.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    smart-link group group-id

    The Smart Link group view is displayed.

  3. Run:

    smart-link manual switch

    Manual switching of data flows is configured.

  4. Run:

    commit

    The configuration is committed.
