Enabling User Traffic Statistics Collection Based on Inner or Outer VLAN IDs on a Device

This section describes how to enable user traffic statistics collection based on inner or outer VLAN IDs on a device.

Context

If PPPoE users go online through user VLAN sub-interfaces that permit packets carrying undefined VLAN tags, the VLAN users can go online through any interface, making it difficult to collect user traffic statistics. After user traffic statistics collection based on inner or outer VLAN IDs is enabled on the router, the router collects user traffic statistics based on inner or outer VLAN IDs. Perform the following steps on the router.

Procedure

Run system-view
The system view is displayed.
Run access user-flow-statistics enable
User traffic statistics collection is enabled based on inner or outer VLAN IDs on the device.
Run commit
The configuration is committed.

Result

After PPPoE users go online through QinQ VLAN tag termination sub-interfaces and any is specified for inner VLAN tags, which means that packets carrying any inner VLAN tags are forwarded, you can run the display access user-flow-statistics configuration or display vlan-statistics pevlan command to check user traffic collection configuration or user traffic statistics on the router.
To collect user traffic statistics in a coming period, run the reset vlan-statistics pevlan command to clear the existing statistics based on a specified inner or outer VLAN ID, and then run the display vlan-statistics pevlan command.
