Cisco Nexus 3548 - Configuring PTP on an Interface

Configuring PTP on an Interface
After you globally enable PTP, it is not enabled on all supported interfaces by default. You must enable PTP
interfaces individually.
Before You Begin
Make sure that you have globally enabled PTP on the switch and configured the source IP address for PTP
communication.
Procedure
PurposeCommand or Action
Enters global configuration mode.switch# configure terminal
Step 1
Specifies the interface on which you are enabling PTP
and enters interface configuration mode.
switch(config) # interface ethernet
slot/port
Step 2
Enables or disables PTP on an interface.switch(config-if) # [no] feature ptp
Step 3
(Optional)
Configures the interval between PTP announce messages
on an interface or the number of PTP intervals before a
timeout occurs on an interface.
switch(config-if) # [no] ptp

switch(config-if) # [no] ptp delay
request minimum interval log

Configures the interval between PTP synchronization
messages on an interface.
switch(config-if) # [no] ptp sync
interval log seconds
Step 6
The range for the PTP synchronization interval is from
-3 log second to 1 log second
(Optional)
Specifies the VLAN for the interface where PTP is being
enabled. You can only enable PTP on one VLAN on an
interface.
switch(config-if) # [no] ptp vlan
vlan-id
