Provides instructions to initiate or terminate a service activation test on an interface, guiding users through Y.1564 test execution steps for operational management.

Use this task to start, stop, and verify Y.1564 service activation tests on network interfaces.

Service activation tests use the Y.1564 methodology to validate SLA compliance and performance parameters, such as throughput and packet loss, on network interfaces. These tests help ensure that new or existing services meet operational requirements before deployment or after configuration changes. You can initiate tests in internal or external directions and stop them individually or collectively as needed.

Procedure

  1. Start a service activation test on an interface with external direction.

    Example:

    Router# ethernet service-activation-test start interface HundredGigE0/0/0/0.100 profile SAT-8K destination 11:22:33:44:55:66 direction external

  2. Start a service activation test on an interface with internal direction.

    Example:

    Router# ethernet service-activation-test start interface HundredGigE0/0/0/0.100 profile SAT-8K destination 11:22:33:44:55:66 direction internal

  3. Stop a service activation test on an interface.

    Example:

    Router# ethernet service-activation-test stop interface HundredGigE0/0/0/0.100 profile SAT-8K destination 11:22:33:44:55:66 direction external

  4. Stop all service activation tests.

    Example:

    Router# ethernet service-activation-test stop all

  5. Use the show ethernet service-activation-test interface command in privileged EXEC mode to verify Y.1564 service activation test interfaces.

    Example:

    Router# show ethernet service-activation-test interface
            HundredGigE0/0/0/0.100
            Interface HundredGigE0/0/0/0.100
            Service activation tests permitted
            Test completed:
            Duration 10 minute(s)
            Information rate 750 Mbps
            Color-blind
            Internal, Two-way, Destination 00:01:00:02:00:03
            Packet size EMIX, Sequence 'abceg', Pattern hex 0x00
            Outer CoS 5
            Results:
            Step 1, Information Rate 750 Mbps
            CIR packets:
            Tx packets: 94286350, bytes: 0
            Rx packets: 94286350, bytes: 38476876568
            FL: 0, FLR: 0%
            FD: Not supported
            IFDV: Not supported
            Out of order packets: 0 (0%)
            Error packets: 0 (0%)
            EIR packets:
            Tx packets: 0, bytes: 0
            Rx packets: 0, bytes: 0
            FL: 0, FLR: 0%
            FD: Not Supported
            IFDV: Not Supported
            Out of order packets: 0 (0%)
            Error packets: 0 (0%)

    The command output shows which interfaces have Y.1564 enabled and your permission status. You can view test status and detailed results including packet statistics and error counts.
