Disabling a Device from Using Tunnel Information as a Hash Factor During Hash Calculation for GTP Packets in an ESQM Scenario

Configuration Guide

Usage Scenarios

In an ESQM scenario, GTP packets are balanced based on tunnel IDs by default. GTP heartbeat packets and data packets are balanced on different paths based on tunnel IDs, which causes inaccurate statistics, run the load-balance hash-fields tunnel-info disable command to disable the device from using tunnel information as a hash factor during hash calculation for GTP packets. By default, the device performs hash calculation for GTP packets based on the 5-tuple information. In this way, GTP heartbeat packets and data packets are hashed to the same path based on the 5-tuple information, improving statistics accuracy.

• By default, a device uses tunnel information as a hash factor during hash calculation for GTP packets. The hash factor is SIP+DIP+tunnel ID.
• The load-balance hash-fields tunnel-info tunnel-type disable command disables a device from using tunnel information as a hash factor during hash calculation for GTP packets.

In VS mode, this configuration process is supported only by the admin VS.

Follow-up Procedure

Run the save command to save the current configuration to the configuration file when a set of configuration is finished and the expected functions have been achieved.
