Use ptp on GigaVUE-TA200 Devices
Use the ptp command to configure the PTP domain, clock mode, and priority on the GigaVUE-TA200 devices. Based on these PTP parameters, the primary source will be selected from the clocks in a network.
Refer to the “Timestamps” chapter in the GigaVUE Fabric Management Guide for more information about how to use PTP to timestamp packets.
Use the following syntax to configure PTP globally for a device:
ptp
alias <string>
domain <value>// Range is 24–43
mode <ordinary | boundary>
local-priority <value> // Range is 1—255
priority2 <value> // Range is 0—255
Use the following syntax to configure PTP globally for a cluster:
ptp
box-id <box-id/all> alias <string>
domain <value>// Range is 24–43
mode <ordinary | boundary>
local-priority <value> // Range is 1—255
priority2 <value> // Range is 0—255
The following table describes the arguments for the ptp command:
Argument |
Description |
|||||||||
alias <string> |
Specifies the name of the PTP for a device. For example: (config) # ptp alias <string> |
|||||||||
box-id <box-id/all> alias <string> |
Specifies the name of the PTP for all devices in a cluster. Ensure that you provide a unique name for each device in the cluster. For example: (config) # ptp box-id <box-id/all> alias <string> |
|||||||||
domain <value> |
Specifies a PTP domain number that will be used for the clock. The valid range is between 24 and 43. The default is 24. For example: (config ptp alias <string>) # domain 24 You can also choose to configure two attributes in a single line. For example, you can configure the PTP alias and domain in a single line as follows: (config) # ptp alias <string> domain 24 |
|||||||||
mode <ordinary | boundary> |
Configures the mode for PTP, ordinary or boundary. For example: (config ptp alias <string>) # mode ordinary |
|||||||||
local-priority <value> |
Specifies a priority value that will be used to determine the PTP source when the BMC algorithm chooses more than one clock as the source. This value overrides the default criteria for the BMC selection. The clock with the lower priority value will be selected. For example, on a specific device, the local priority of a port is compared with the local priority of the clock. Based on the following criteria, the source is determined:
The valid range is between 1 and 255. The default is 128. For example: (config ptp alias <string>) # local-priority 128 |
|||||||||
priority2 <value> |
Specifies a priority value that will be used to determine the primary source in a network. For example, if there are two clocks in a network that match the default criteria, the clock that has the lower priority value will be selected as the primary source. The valid range is between 0 and 255. The default is 128. For example: (config ptp alias <string>) # priority2 128 |
