The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter describes the system management commands that begin with P.
To configure the latency threshold value on an interface, use the packet latency threshold command. To remove the threshold value, use the no form of this command.
packet latency threshold threshold-value
Module number. The range is from 8 to 536870904 nano seconds. |
|
|
This command does not require a license.
You apply this command to egress interfaces where SPAN-on-Latency functioanlity is needed. When latency on the egress interface exceeds the configured threshold, packets are spanned on the interface configured as the destination port for the SPAN-on-Latency session. Only one SPAN-on-Latency session is supported at a time.
This example shows how to set the latency threshold value to 530000000 nano seconds:

To power off a module, use the poweroff module command. To return power to the module, use the no form of this command.
|
|
This example shows how to power off module 2:

To configure the interval between PTP announcement messages on an interface or the number of PTP intervals before a timeout occurs on an interface, use the ptp announce command. To disable this feature, use the no form of this command.
ptp announce { interval log-seconds | timeout count }
The number of log seconds between PTP announcement messages. The range is from 0 to 4 seconds. |
|
The number of PTP intervals before a timeout occurs on the interface. The range is from 2 to 10. |
|
|
This example shows how to set the announcement interval on interface 5/1 to 1:
To configure the minimum interval allowed between PTP delay request messages when the port is in the master state, use the ptp delay request minimum interval command. To disable this feature, use the no form of this command.
ptp delay request minimum interval log-seconds
no ptp delay request minimum interval
The number of log seconds between PTP delay request messages. The range is from -1 to 6 seconds. |
|
|
This example shows how to set the minimum delay request interval to 3:
To configure the domain number to use for this clock, use the ptp domain command. PTP domains allow you touse multiple independent PTP clocking subdomains on a single network.
Configures the domain number to use for this clock. The range is from 0 to 128. |
|
|
This example shows how to configure the domain number for use with a clock:
|
|
---|---|
Configures the priority 1 value to use when advertising this clock. |
|
Configures the priority 1 value to use when advertising this clock. |
|
To configure the priority1 value to use when advertising this clock, use the ptp priority1 command.
The configured value overrides the default criteria (clock quality, clock class, etc.) for best master clock selection. Lower values take precedence. The range is from 0 to 255. |
|
|
This example shows how to set the priority1 value used to advertise this clock:
|
|
---|---|
Configures the priority2 value to use when advertising this clock. |
|
To configure the priority2 value to use when advertising this clock, use the ptp priority2 command.
|
|
This example shows how to set the priority2 value used to advertise this clock:
|
|
---|---|
Configures the priority1 value to use when advertising this clock. |
|
To configure the source IP address for all PTP packets, use the ptp source command. To unconfigure the source IP address for all PTP packets, use the no form of this command.
ptp source ip-address [ vrf vrf ]
no ptp source ip-address [ vrf vrf ]
Specifies the source IP address for all PTP packets. The IP address can be in IPv4 or IPv6 format. |
|
|
|
This example shows how to configure the source IP address for all PTP packets:

Configures the priority 1 value to use when advertising this clock. |
|
Configures the priority 1 value to use when advertising this clock. |
|
To configure the interval between PTP synchronization messages, use the ptp sync interval command. To disable this feature, use the no form of this command.
The number of log seconds between PTP synchronization messages on an interface. The range is from -3 seconds to 1 second. |
|
|
This example shows how to set the PTP synchronization interval to -3:
To specify the VLAN for the interface where PTP is being enabled, use the ptp vlan command. To disable this feature, use the no form of this command.
The VLAN ID for the interface where PTP is being enabled. The range is from 1 to 4094. |
|
|
This example shows how to specify VLAN 10 as the interface where PTP is being enabled:
