Configure the PTP clock type on the switch and optionally specify a profile for the clock. OS10 supports the following clock
types: boundary and end-to-end transparent. OS10 supports the system default profile and ITU G.8275.1 profile. The profile
defines the set of parameters, allowed values of parameters, and default value of parameters. To configure PTP clock:
OS10(config)# ptp clock boundary
Configure the PTP domain
A PTP domain is a logical group of clock devices where all the clocks have the same time synchronized from the grandmaster
clock. To configure a domain for PTP clock:
OS10(config)# ptp domain 1
Configure the source IP address for multicast transport
To configure source IP address for PTP multicast packets:
OS10(config)# ptp source ipv4 10.10.10.1
NOTE: The IPv4 or IPv6 address that you configure must correspond to a configured L3 interface (physical, Loopback,
VLAN, or port channel) and the interface must be operationally up.
Configure the priority1 attribute
Priority1 has the highest priority in master clock device selection. Lower values have higher priority.
OS10(config)# ptp priority1 125
Configure the priority2 attribute
Priority2 has the fifth precedence in master clock device selection. Lower values have higher priority.
OS10(config)# ptp priority2 120
Configure the local priority attribute for the PTP clock
(Applicable only for the G.8275.1 profile) PTP uses the local priority attribute to compare a potential GM data set.
OS10(config)# ptp local-priority 120
Configure the PTP clock to set the system time
To configure the PTP clock to set the system time:
OS10(config)# ptp system-time enable
Interface-level configurations
Enable PTP on an interface
To enable PTP on an interface:
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# ptp enable
Configure the PTP role
A PTP interface can operate in master or slave role. To configure PTP role:
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# ptp role master
NOTE:
The PTP role is set to dynamic by default. If the role is set to dynamic, PTP uses the BMCA to select the master or
slave role.
