(Optional) Configuring Accounting Packet Merging for Value-added Services

To reduce the number of packets sent to a RADIUS accounting server, configure accounting packet merging for value-added services.

Context

When a large number of users go online and each user applies for many value-added services, a large number of accounting packets are generated. Due to the limited processing capability of a RADIUS accounting server, the number of accounting packets sent by a device to a RADIUS accounting server must be reduced to relieve the pressure on the RADIUS accounting server.
