DetNetOAM commands

binding path-group-id

Use binding path-group-id to bind a path group to a DetNetOAM instance.

Use undo binding path-group-id to cancel the path group binding for a DetNetOAM instance.

Syntax

binding path-group-id pathgroupID

undo binding path-group-id

Default

No path group is bound to a DetNetOAM instance.

Views

DetNetOAM instance view

Predefined user roles

network-admin

Parameters

pathgroupID: Specifies a path group by its path group ID. The value range for this argument is 1 to 4000.

Usage guidelines

Application scenarios

A path group is a group of SRv6 ECMP paths. DetNetOAM probe packets are forwarded through SRv6 paths. A path group is uniquely identified by its path group ID. After you bind a path group to a DetNetOAM instance and enable DetNetOAM probing for the instance, DetNetOAM measures the timeslot deviation and latency for each path in the path group with the same probing parameters. This assists the DetNet module in achieving deterministic forwarding of service packets.

Restrictions and guidelines

You can bind only one path group to a DetNetOAM instance, and a group path can be bound to only one DetNetOAM instance.

If DetNetOAM probing is enabled for a DetNetOAM instance, you cannot change the DetNet path bound to the instance. To change the bound path, first use the undo measure enable command to disable DetNetOAM probing for the instance.

Examples

# Bind path group 10 to DetNetOAM instance abc.

<Sysname> system-view

[Sysname] detnetoam enable

[Sysname-detnetoam] instance abc

[Sysname-detnetoam-instance-abc] binding path-group-id 10

binding-path-id

Use binding-path-id to bind a DetNet path to a DetNetOAM instance.

Use undo binding-path-id to cancel the path binding for a DetNetOAM instance.

Syntax

binding-path-id pathID

undo binding-path-id

Default

No path is bound to a DetNetOAM instance.

Parameters

path-id: Specifies a DetNet path by its path ID. The value range for this argument is 1 to 4000.

Usage guidelines

A path ID is generated by the DetNet module to uniquely identify a DetNet path. Use this command to bind a DetNet path to a DetNetOAM instance, and DetNetOAM probe packets will be forwarded along the path. You can bind only one DetNet path to a DetNetOAM instance, and a path can be bound to only one DetNetOAM instance. For more information about DetNet paths, see DetNet configuration in Deterministic Network Technologies Configuration Guide.

If DetNetOAM probing is enabled for a DetNetOAM instance, you cannot change the DetNet path bound to the instance. To change the bound path, first use the undo measure enable command to disable DetNetOAM probing for the instance.

Examples

# Bind DetNet path 10 to DetNetOAM instance abc.

<Sysname> system-view

[Sysname] detnetoam enable

[Sysname-detnetoam] instance abc

[Sysname-detnetoam-instance-abc] binding-path-id 10

measure enable

data-size

Use data-size to set the payload size for each probe packet.

Use undo data-size to restore the default.

Syntax

Data-size  size

undo data-size

Default

The payload size is 128 bytes.

Views

Predefined user roles

network-admin

Parameters

size: Specifies the payload size in the range of 84 to 1024 bytes.

Usage guidelines

The sum of the payload size specified by using this command and the IP header length of each probe packet cannot be larger than the MTU size of any interface on the probed link. If the sum exceeds the MTU size of an interface, the probe packet will be fragmented. This command takes effect only for DetNetOAM instances bound to path groups.

Examples

# Set the payload size to 90 bytes for each probe packet.

<Sysname> system-view

[Sysname-detnetoam] instance abc

[Sysname-detnetoam-instance-abc] data-size 90

delay-measure enable

Use delay-measure enable to enable latency measurement for a DetNetOAM instance.

Use undo delay-measure enable to disable latency measurement for a DetNetOAM instance.

Syntax

delay-measure enable

undo delay-measure enable

Default

Latency measurement is disabled for a DetNetOAM instance.

Views

DetNetOAM instance view

Predefined user roles

network-admin

Usage guidelines

Use this command to enable latency measurement for a DetNetOAM instance. Use this command in conjunction with the the measure enable command. You can enable DetNetOAM probing after you create a DetNetOAM instance on the ingress edge node of a DetNet network, configure the probe interval and probe packet parameters, and bind a path group. Latency measurement starts after DetNetOAM probing is enabled by using the measure enable command. The delay-measure enable command does not enable the device to send probe packets. After you execute this command, you can still use other commands to edit the instance settings.

Examples

# Enable latency measurement for DetNetOAM instance abc.

[Sysname] detnetoam enable

[Sysname-detnetoam] instance abc

[Sysname-detnetoam-instance-abc] delay-measure enable

detnetoam enable

Use detnetoam enable to enable DetNetOAM and enter DetNetOAM view. If DetNetOAM has been enabled, this command enters DetNetOAM view.

Use undo detnetoam enable to disable DetNetOAM.

Syntax

detnetoam enable

undo detnetoam enable

Default

DetNetOAM is disabled.

Views

Predefined user roles
