Usage
Information
When you enable this configuration, PTP sets the system time on the switch only if the servo clock
is phase locked. You cannot enable the PTP system time if the system is configured as an NTP client.
However, you can enable the PTP system time if the system is configured as an NTP server. The no form
of this command removes the configuration.
Example
OS10(config)# ptp system-time enable

[negotiation-enable] | slave [negotiation-enable]}} | layer2 [address
{forwardable | non-forwardable}]
Parameters
● ipv4 multicast—Enables IPv4 multicast as the transport method.
● ipv4 unicast master—Enables IPv4 unicast master mode.
● ipv4 unicast master negotiation-enable—Enables unicast negotiation (signaling support)

● ipv6 unicast slave—Enables IPv6 unicast slave mode.
● ipv6 unicast slave negotiation-enable—Enables unicast negotiation (signaling support)
on slave to request for unicast transmission to master.
● layer2—Enables Layer2 protocol (untagged or 802.1Q tagged Ethernet packet) as the transport
method.
● layer2 address forwardable—Enables the forwardable destination address
(01:1B:19:00:00:00) for the layer2 transport method.
