Usage Guidelines

Usage Scenario

This command configures the inbound and outbound rate for the service policy template.

Prerequisites

This service policy template has been created.

Configuration Impact

A service is generated according to a service policy template. The rate-limit determines the bandwidth of a service.

Precautions

This command is supported only on the admin VS.

The PIR must be greater than or equal to the CIR.
The PBS should be larger than the CBS.
The CBS and PBS should be larger than the 187 times of the packet length.
The flow-queue-pbs should be larger than the CBS.
