sla name

Function

The sla name command creates a link quality indicator.

The undo sla name command deletes a link quality indicator.

Format

sla name sla-name { delay delay | jitter jitter | loss loss } ^*

undo sla name sla-name

Parameters

Parameter	Description	Value
sla-name	Specifies a link quality indicator.	The value is a string of case-sensitive characters. The length of a name without spaces ranges from 1 to 31 characters. The length of a name with spaces ranges from 3 to 33 characters. If a name contains spaces, the name must be enclosed with quotation marks (for example, "sla for test").
delay	Specifies the maximum delay of a link. If the link delay exceeds the value of this parameter, the link quality indicator is not met.	The value is an integer ranging from 1 to 60000, in milliseconds.
jitter	Specifies the maximum jitter of a link. If the link jitter exceeds the value of this parameter, the link quality indicator is not met.	The value is an integer ranging from 1 to 60000, in milliseconds.
loss	Specifies the maximum packet loss rate of a link. If the packet loss rate of a link exceeds the value of this parameter, the link quality indicator is not met.	The value is an integer ranging from 1 to 100, in percentage.

Usage Guidelines

Versions earlier than V600R007C20SPC300, All models except USG6635E/6655E, USG6680E and USG6712E/6716E support this command.

In V600R007C20SPC300 and later versions, all models support this command.

Link quality indicators are used to determine whether an intelligent uplink selection member link meets quality requirements. A link quality indicator takes effect only when it is referenced together with a health check object in a global routing policy or multi-ISP policy-based route.

At least one of delay, jitter, and loss must be specified. Unspecified indicators are not concerned about.

After health check and link quality indicator objects are referenced in a global routing policy or multi-ISP policy-based route, the FW checks whether the link quality (delay, jitter, and packet loss rate) meets the quality requirements of link quality indicators in real time. The links that do not meet the requirements are not allowed to participate in intelligent uplink selection until their link quality meets the requirements.

Example

# Create link quality indicator sla1 to set the maximum link jitter to 6 ms and the maximum packet loss rate to 6%.
