Parameters

system-defined: Specifies a system-defined flow group.

·     ip: Specifies the system-defined IP flow group.

·     vxlan: Specifies the system-defined VXLAN flow group.

slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command displays the configuration and application status on the active MPU.

Examples

# Display the configuration and application status of the system-defined VXLAN flow group.

<Sysname> display telemetry flow-group system-defined ip slot 1

Flow group named system-defined-ip (Inactive, System-defined)

Field

Description

Flow group named system-defined-ip (Successful, System-defined)

Name and application status of the flow group. Values for the application status include:

·     Successful—The flow group is applied successfully.

·     Failed—The flow group fails to be applied for some reasons other than incomplete flow group configuration.

·     Inactive—The flow group has not been administratively applied.

·     Incomplete—The flow group fails to be applied because its configuration is incomplete.

telemetry apply flow-group

Use telemetry apply flow-group to apply a flow group.

Use undo telemetry apply flow-group to remove the application of a flow group.

Syntax

telemetry apply flow-group system-defined { ip | vxlan }

undo telemetry apply flow-group system-defined { ip | vxlan }

Default

No flow group is applied.

network-admin

Parameters

system-defined: Specifies a system-defined flow group.

·     ip: Specifies the system-defined IP flow group.

·     vxlan: Specifies the system-defined VXLAN flow group.

The device has two system-defined flow groups: one IP flow group named system-defined-ip and one VXLAN flow group named system-defined-vxlan. The two flow groups are not configurable.

The IP flow group generates flow entries based on the 5-tuple.

The VXLAN flow group generates flow entries based on the VXLAN  ID and the inner 5-tuple.

The two flow groups take effect on all traffic.

Examples

# Apply the system-defined IP flow group.

<Sysname> system-view

[Sysname] telemetry apply flow-group system-defined ip

telemetry flow-group aging-time

Use telemetry flow-group aging-time to set the aging time for flow entries.

Use undo telemetry flow-group aging-time to restore the default.

Syntax

telemetry flow-group aging-time aging-time

undo telemetry flow-group aging-time

Default

The aging time for flow entries is 15 minutes.

Parameters

aging-time: Specifies the aging time for flow entries in minutes. The value range for this argument is 1 to 100.

Examples

# Set the aging time for flow entries to 20 minutes.

<Sysname> system-view

[Sysname] telemetry flow-group aging-time 20
