sac (NQA test flow view)

Function

The sac command sets the service acceptance criteria (SAC) parameters for NQA test flows.

The undo sac command deletes the SAC parameters.

By default, no SAC parameters are configured for NQA test flows.

Format

sac flr flr-value ftd ftd-value fdv fdv-value

Parameters

Parameter	Description	Value
ftd ftd-value	Specifies the frame transfer delay (FTD).	The value is an integer ranging from 1 to 10000000, in microseconds.
fdv fdv-value	Specifies the frame delay variation (FDV).	The value is an integer ranging from 1 to 10000000, in microseconds.
flr flr-value	Specifies the frame loss ratio (FLR).	The value is an integer that ranges from 0 to 100000, expressed in 1/100000.

Usage Guidelines

Usage Scenario

The SAC describes network service quality that a carrier promises before rolling out network services. The SAC consists of network performance parameters, such as the FLR, FTD, and FDV.

The SAC must be specified for an Ethernet service activation test. The initiator calculates these counters (including FLR, FTD, and FDV) based on received packets, compares these counters with configured ones, and determines whether test flow tests are successful, and network service quality meets the requirements.

Precautions

This command is only run for an Ethernet service activation test instance.
