SRPM commands

activate profile

Use activate profile to activate a link-based delay profile.

Use undo activate profile to deactivate a link-based delay profile.

Syntax

activate profile

undo activate profile

Default

A link-based delay profile is not activated.

Views

Link-based delay profile view

Predefined user roles

network-admin

Usage guidelines

After creating or modifying a delay profile, you must activate the profile for the new configuration to take effect.

Reactivating a delay profile clears history measurement statistics on SRPM-enabled interfaces that are associated with this delay profile. The interfaces will use the new configuration to start new measurement sessions.

Before modifying parameters in a delay profile or terminating measurement sessions related to that profile, you must use the undo activate profile command to deactivate that profile.

Examples

# Activate the link-based delay profile named test.

<Sysname> system-view

[Sysname] srpm

[Sysname-srpm] delay-profile link-based test

[Sysname-srpm-delay-profile-link-based-test] activate profile

delay-profile link-based

Use delay-profile link-based to create a link-based delay profile and enter its view, or enter the view of an existing link-based delay profile.

Use undo delay-profile link-based to delete a link-based delay profile.

Syntax

delay-profile link-based profile-name

undo delay-profile link-based profile-name

Default

No link-based delay profiles exist.
