Displaying the PTP Configuration
Displaying the PTP Configuration
To display the PTP configuration, use one or more of these privileged EXEC commands in
Table 9-2
.
Step 4
ptp
{
announce
{
interval
value
|
timeout
value
}
|
delay-req
interval
value
|
enable
|
sync
{

|
limit

}}
Specify the settings for the timing messages. These options are only available
when the switch is in boundary mode.
•
For
announce interval
, specify the time for sending announce messages. The
range is 0 to 4 seconds. The default is 1 (2 seconds).
•
For
timeout value,
specify the time for announcing timeout messages. The
range is 2 to 10 seconds. The default is 3 (8 seconds).
•
For
delay request interval
, specify the time recommended to the member
devices to send delay request messages when the port is in the master state. The
range is –1 second to 6 seconds. The default is 5 (32 seconds).
•
For
sync interval
, enter the time for sending synchronization messages. The
range is –1 second to 1 second. The default is 1 second.
•
For
sync limit
, specify the maximum clock offset value before PTP attempts
to resynchronize. The range is 50 to 500000000 nanoseconds. The default
is 50000 nanoseconds.
Note
We recommend against setting the sync limit below the default (50000
nanoseconds). Use values below 50000 nanoseconds only in networks
with a high-precision grand master clock.
Step 5

Return to privileged EXEC mode.
Step 6
show running-config
Verify your entries.
Step 7
copy running-config
