Configuring ESQM End-to-End Performance Measurement

After the end-to-end performance measurement function is configured, you can collect information, such as the packet type, timestamp, and packet statistics, for packet forwarding path restoration, traffic restoration, and fault detection.

Context

Traditional communication networks are unable to "perceive" services, preventing customers' ever-changing service requirements from being responded to in real time. To solve this problem, ESQM has been developed to help devices monitor the quality of services on networks. This technology integrates network deployment with service requirements and provides the data that is the foundation for automatic and intelligent network lifecycle management.

Procedure

Run system-view
The system view is displayed.
Run esqm
The ESQM view is displayed.
(Optional) Run esqm session aging-time sctp tmval
An aging time is set for SCTP flow tables.

The configured aging time takes effect only for subsequently created SCTP flow tables.
(Optional) Run esqm protocol tcp enable
The device is enabled to create flow tables for sampled TCP protocol packets.
(Optional) Run esqm protocol { sctp | gtp } disable
The device is disabled from creating flow tables for sampled SCTP, or GTP protocol packets.
(Optional) Run esqm filter permit ip ip-addr mask masklen
The function of filtering sampled packets is enabled.
Run any of the following commands:
- To perform ESQM for inbound or outbound packets on all the interfaces to which a VPN instance is bound, run the esqm service-stream { inbound | outbound } vpn-instance vpn-instance-name command in the ESQM view.
- To perform ESQM for inbound or outbound packets on all the interfaces to which no VPN instance is bound, run the esqm service-stream { inbound | outbound } command in the ESQM view.
- To perform ESQM for inbound or outbound packets on an interface, run the following commands:
  1. Run quit
    Exit from the ESQM view.
  2. Run interface interface-type interface-num
    The interface view is displayed.
  3. Run esqm service-stream { inbound | outbound }
    A packet sampling direction is configured for ESQM on the interface.
  4. Run quit
    Return to the system view.
Run commit
The configuration is committed.
