Global configurations You can configure the following settings globally. Configure the PTP clock 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 System management 171
