Collecting Statistics About L3VPN Traffic

Collecting Statistics About L3VPN Traffic

Prerequisites

L3VPN traffic statistics collection is applicable to the interface traffic at the user side of a VPN. Before collecting L3VPN traffic statistics, you need to enable the L3VPN traffic statistics function.

NOTE:
  • Currently, L3VPN traffic statistics collection can count only unicast packets.
  • In L3VPN over MPLS TE scenarios, if the device is enabled to collect L3VPN traffic statistics and traffic statistics on an MPLS TE tunnel interface simultaneously, packets received from the interface bound to a VPN instance are not counted as L3VPN traffic.
  • Enabling L3VPN traffic statistics function may affect the forwarding performance. For example, when all interfaces provide line-speed forwarding, some interface may be unable to forward packets at line speed. Exercise caution when you enable traffic statistics on a VLANIF interface.
  • L3VPN traffic statistics is unavailable for error packets.

Perform the following steps on the device:

Procedure

  1. Run the system-view command to enter the system view.
  2. Run the ip vpn-instance vpn-instance-name command to enter the VPN instance view.
  3. Run the traffic-statistics enable command to enable the function of collecting statistics about L3VPN traffic.
