Y.1564 Test configuration (Service Performance ▶ Y.1564 ▶ Configuration)
| Parameter | Description |
|---|---|
| Source device | Device that will be the source of the test. When you click in this field, a dialog pops up. You can select a device from the Legacy orchestrator inventory |
General
| Parameter | Description |
|---|---|
| Test name | A name for the Y.1564 test profile. A maximum of 28 characters is supported. Do not include spaces, forward slashes, or backslashes in the name. |
| Test description | A description to identify the Y.1564 test and its characteristics. |
| Delay measurement type | The delay measurement type can be either one-way delay or two- way delay Note: You must enable the SAT protocol in order to use one-way delay measurements. |
| Outgoing port | The port on which to send flow(s). SAT capable possible values:
|
| Device time SYNC mandatory | Check box to enable or disable mandatory device sync time. When this option is enabled, the tests will be performed only if both devices performing the Y.1564 test are synchronized using one of the supported timing mechanisms. When this option is disabled, the tests will be performed, but valid results will be displayed only if both devices performing the Y.1564 test are synchronized using one of the supported timing mechanisms. This type of test may be useful to test applications where delay is not important, but other parameters, such as CIR or EIR, are important. Note: For one-way delay measurement only. |
Duration
| Parameter | Description |
|---|---|
| Configuration step duration (seconds) | The duration, expressed in seconds, of each step during the configuration test. Range: 1–60 seconds. Note: This parameter is also used for the burst SLA Test. |
| Performance step duration (minutes) | The duration of the performance test, expressed in minutes. Range: 1–1,440 minutes |
| Enable configuration test | Check box to enable the configuration test allows use of the policing test and step test under each service (traffic flow) configured. It allows you to run successive tests at rates of 25% CIR, 50% CIR, 75% CIR, and 100% of CIR, CIR+EIR, and Policing. For Policing:
|
| Enable performance test | Check box to enable or disable the performance test. You must configure at least one service when you enable performance test. Note: The performance test is run at 100% CIR. |
| Enable parallel test | Check box to enable or disable the Parallel Service Configuration test.
|
| Enable burst SLA test | Enable or disable the burst SLA test. (Default is disabled) |
General far-end settings
| Parameter | Description |
|---|---|
| Test type | The type of test traffic:
|
| Group reverse tests |
|
| Near-end UDP port | The near-end UDP port number used to generate the test's PDU. Note: Applies to Layer-3 traffic only. |
| Far-end UDP port | The far-end UDP port number associated with the IP address of the unit that will receive, process and display the traffic statistics and report. Notes: Applies to Layer-3 traffic only. For reporting to work properly, you must set the port to a value in the range of 0–65535 but you cannot set the destination port value to 8793, since this is Accedian's proprietary port number. For information on destination ports default values, refer to. |
General (flow parameters)

| Availability | Selectable check box to indicate availability. |
| Out-of-order percentage | This parameter can be enabled or disabled. When enabled, the Out of Order (OOO) frames/packets count is considered in the pass or fail of the network test. |
| Preserve DSCP and PCP Verification | When this option is enabled, the peer unit verifies that the DSCP/PCP values configured in the test traffic have not changed. If they have changed, the test will fail. Note: Applies to one-way delay tests only. |
Bandwidth (flow parameters)
| Parameter | Description |
|---|---|
| CIR | The CIR value provided here can be interpreted as the maximum sustained information rate that the network has committed to transfer while meeting the performance level guaranteed in the Service Level Agreement (SLA). The CIR and EIR values specified in the bandwidth profile are used by the Y.1564 tool to define the Configuration, Performance and Policing Tests to be executed. |
| EIR | The EIR value provided here can be interpreted as the maximum sustained information rate, over and above the CIR, at which traffic is carried though the network, if possible. |
| Frame Size Type | The test will be performed with this type of frame size. |
| Packet Size | The size of each frame for the test traffic. |
| User define | The size of each user-defined packet for the test traffic. |
| Sequence of sizes | For the EMIX frame size type, the packet size values used in the test and the specific sequence in which they are sent. |
| Committed Burst Size | The maximum number of kibibytes available for a burst of frames that are sent at the port's speed and remain CIR conformant. Range: 0 to 10,000 KiB. |
| Excess Burst Size | This parameter is not currently used and is grayed out. This is for future implementation only. |
Acceptance (flow parameters)
| Parameter | Description |
|---|---|

|
| Frame Loss Ratio | The ratio below which the test passes. |
| M Factor | The M factor (margin factor) is added to the Service Acceptance Criteria in the policing test to take into account the effect of the CBS and EBS on the total rate. The policing test will pass if IR-T ≤ CIR + EIR + M. Where:
|
| Out-of-order percentage (%) | The percentage of Out of Order (OOO) frames/packets. |
Near-end VLAN (flow parameters for the downstream VLAN)
| Parameter | Description |
|---|---|
| VLAN 1 Header | Check box to enable or disable VLAN 1 header. This encapsulates all frames with one VLAN header. If the VLAN 1 header is enabled, the packet size increases by 4 bytes. For example:
