Maintaining VLAN

Maintaining VLAN

A command of clearing statistics helps to locate the faults in a VLAN.

Clearing the Statistics of VLAN Packets

Before collecting traffic statistics in a specified time period on an interface, you need to reset the original statistics on the interface.

Context

Statistics about VLAN packets cannot be restored after you clear it. So, confirm the action before you use the command.

To clear the Statistics of VLAN Packets, run the following reset command in the user view:

Procedure

  • Run the reset statistics interface interface type interface number vlan vlan-id command to clear the VLAN packet statistics on a specified interface.

Monitoring the VLAN Operating Status

This section describes how to monitor the VLAN operating status.

Context

In routine maintenance, you can run the following command in any view to check the VLAN operating status.

Procedure

  • Run the display vlan statistics command to view VLAN packet statistics.

    By default, collecting VLAN packet statistics is disabled. Before you run the display vlan statistics command to view VLAN packet statistics and locate faults, run the statistic enable command in the specific VLAN view to enable the device to collect VLAN packet statistics. If VLAN packet statistics collection is disabled, you cannot obtain statistics.

  • Run the display vlan statistics command to check statistics about discarded BUM packets in a specified VLAN.

    By default, collecting statistics about discarded BUM packets is disabled. Before you run the display vlan statistics command to check statistics about discarded BUM packets in a VLAN for fault locating, run the statistic discard enable command in the VLAN view to enable collection on traffic statistics about discarded BUM packets. If you do not run the statistic discard enable command, the statistics cannot be collected.

  • Run the display statistics interface interface-type interface-number vlan vlan-id command to view statistics about both sent and received packets on a specific interface in a specific VLAN.

    By default, VLAN packet statistics collection on a specific interface in a specific VLAN is disabled. Before you view packet statistics on a specified interface in a specific VLAN and locate faults, run the statistic enable vlan command in the specific interface view. If the statistics enable vlan command is not executed, statistics cannot be displayed.

  • Run the monitor interface-vlan-statistics interface interface-type interface-number vlan vlan-id [ interval interval-value | times { times-value | infinity } ] command to monitor traffic statistics on an interface of a specified VLAN.

    By default, once the monitor interface-vlan-statistics command is run on an interface, the system displays traffic statistics five times at an interval of 10s. To stop the statistics display, press Ctrl+C.
