The ptp announce interval command configures the interval at which the configuration mode interface sends PTP announce messages. The no ptp announce interval command resets the announce interval to its default of 1 (2 seconds).
Command Mode
Interface-Ethernet Configuration
Interface-Port Channel Configuration
Command Syntax
ptp announce interval log_interval
no ptp announce interval
default ptp announce interval
Parameters
log_interval The number of log seconds between PTP announce messages (base 2 log (seconds)). Value ranges from -3 (1/8 second) to 4 (16 seconds); default value is 1 (2 seconds).
- These commands set the interval between PTP announce messages sent by
interface ethernet 5 to
4
seconds.
switch(config)# interface ethernet 5 switch(config-if-Et5)# ptp announce interval 2 switch(config-if-Et5)# - These commands reset the PTP announce interval on
interface ethernet 5 to the default value
of 1 (2
seconds).
switch(config)# interface ethernet 5 switch(config-if-Et5)# no ptp announce interval switch(config-if-Et5)#
ptp announce timeout
The ptp announce timeout sets the timeout multiplier for the configuration-mode interface. The timeout multiplier is the number of announcement intervals that the interface will wait without receiving a PTP announce message before a timeout occurs; the range is from 2 to 255. The default multiplier is 3, which results in a 6-second timeout interval when the announce interval is set to the default of 2 seconds. To configure the announce interval, use the ptp announce interval command.

Mean path delay is the mean time in nanoseconds that PTP packets take to travel between PTP master and slave. The ptp monitor threshold mean-path-delay command configures the mean-path-delay threshold in nanoseconds. When this threshold is configured, a Syslog message is generated if the value of the most recently calculated mean path delay is greater than or equal to this value.
The no ptp monitor threshold mean-path-delay and default ptp monitor threshold mean-path-delay commands clear the threshold value and prevent further Syslog messages from being generated for this parameter.
Command Mode
Global Configuration
Command Syntax
ptp monitor threshold mean-path-delay threshold
no ptp monitor threshold mean-path-delay
default ptp monitor threshold mean-path-delay
Parameter
threshold threshold in nanoseconds. Values range from 0 to 1000000000 (1 second).
Example
switch(config)# ptp monitor threshold mean-path-delay 2000ptp monitor threshold offset-from-master
PTP offset is the difference in nanoseconds between master and slave time. The ptp monitor threshold offset-from-master command configures the offset-from-master threshold in nanoseconds. A Syslog message is generated if the most recently calculated time offset from the PTP master is outside of the range (-<threshold>, <threshold>). The maximum offset threshold is one second.
The no ptp monitor threshold offset-from-master and no ptp monitor threshold offset-from-master commands clear the threshold value and prevents further Syslog messages from being generated for this parameter.
Command Mode

switch(config)#ptp monitor threshold skew
PTP skew is the clock frequency difference between master and slave. The ptp monitor threshold skew command configures the value of the skew-threshold percentage. A Syslog message is generated if the value of the most recently calculated skew is not in the range (1/(1+threshold), 1*(1+threshold)).
The no ptp monitor threshold skew and default ptp monitor threshold skew commands clear the threshold value and prevent further Syslog messages from being generated for this parameter.
Command Mode

switch(config)#ptp monitor
The ptp monitor command enables and disables PTP monitoring on the switch. When PTP monitoring is enabled, the switch records PTP status and configuration information (which can be viewed using the show ptp monitor command) and generates Syslog messages for metrics whose threshold values have been configured.
