emdi alarm threshold

Function

The emdi alarm threshold command configures the alarm thresholds of the packet loss rate and packet disorder rate in EMDI detection.

The undo emdi alarm threshold command restores the default configuration.

By default, the alarm thresholds corresponding to various EMDI monitoring periods are shown in Guide:

This command is supported only on the NetEngine 8000 F1A.

Format

emdi alarm { rtp-lr | rtp-ser } { sd | hd | 4k } threshold threshold-value

undo emdi alarm { rtp-lr | rtp-ser } { sd | hd | 4k } threshold [ threshold-value ]

Parameters

Parameter	Description	Value
rtp-lr	Indicates the packet loss rate of RTP packets.	-
rtp-ser	Indicates the packet disorder rate of RTP packets.	-
sd	Indicates the SD video source.	-
hd	Indicates the HD video source.	-
4k	Indicates the 4K video source.	-
threshold-value	Specifies an alarm threshold.	The value is an integer that ranges from 1 to 5000, in 1/100000.

Usage Guidelines

Usage Scenario

When a device deployed with the EMDI detection solution detects that the packet disorder rate and packet loss rate of various video streams exceed the specified thresholds, the device reports an alarm to the NMS. To configure the alarm thresholds of the packet loss rate and packet disorder rate for various video sources (SD, HD, and 4K), run the emdi alarm threshold command.

By default, the alarm thresholds corresponding to various EMDI monitoring periods are as follows:

Monitoring Period	Threshold of Packet Loss Rate (SD)	Threshold of Packet Loss Rate (HD)	Threshold of Packet Loss Rate (4K)	Threshold of Packet Disorder Rate (SD)	Threshold of Packet Disorder Rate (HD)	Threshold of Packet Disorder Rate (4K)
60s	38	9	3	38	9	3
30s	100	100	100	100	100	100
10s	100	100	100	100	100	100

Configuration Impact

When a detection indicator equals to the configured alarm threshold, an alarm is generated.

Precautions

When the monitoring period has been changed using the emdi monitor-period command, the alarm thresholds are automatically changed to the default values corresponding to the new monitoring period.

Example

# Set the alarm threshold of RTP packet loss rate for the SD video source to 1/100000.
