PurposeCommand or Action
(Optional)
Configures the domain number to use for this clock. PTP
domains allow you to use multiple independent PTP clocking
subdomains on a single network.
switch(config) # [no] ptp
domain number
Step 4
The range for the number is from 0 to 128.
(Optional)
Configures the priority1 value to use when advertising this
clock. This value overrides the default criteria (clock quality,
switch(config) # [no] ptp
priority1 value
Step 5
clock class, and so on) for the best master clock selection.
Lower values take precedence.
The range for the value is from 0 to 255.
(Optional)
Configures the priority2 value to use when advertising this
clock. This value is used to decide between two devices that
switch(config) # [no] ptp
priority2 value
Step 6
are otherwise equally matched in the default criteria. For
example, you can use the priority2 value to give a specific
switch priority over other identical switches.
The range for the value is from 0 to 255.
(Optional)
Displays the PTP status.
switch(config) # show ptp brief
Step 7
(Optional)
Displays the properties of the local clock.
switch(config) # show ptp clock
Step 8
(Optional)
Saves the change persistently through reboots and restarts by
copying the running configuration to the startup configuration.
switch(config)# copy
running-config startup-config
Step 9
The following example shows how to configure PTP globally on the device, specify the source IP address for
PTP communications, and configure a preference level for the clock:
switch# configure terminal
switch(config)# feature ptp
switch(config)# ptp source 10.10.10.1
switch(config)# ptp priority1 1
switch(config)# ptp priority2 1
switch(config)# show ptp brief
