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
Supported
Releases
10.5.1.0 or later
ptp transport
Configures the PTP transport method for an interface.
Syntax
ptp transport {ipv4 {multicast | unicast {master [negotiation-enable] |
slave [negotiation-enable]}} | ipv6 {multicast | unicast {master
[negotiation-enable] | slave [negotiation-enable]}} | layer2 [address
{forwardable | non-forwardable}]
Parameters
ipv4 multicastEnables IPv4 multicast as the transport method.
ipv4 unicast masterEnables IPv4 unicast master mode.
ipv4 unicast master negotiation-enableEnables unicast negotiation (signaling support)
on master to grant unicast transmission requests from slave.
ipv4 unicast slaveEnables IPv4 unicast slave mode.
ipv4 unicast slave negotiation-enableEnables unicast negotiation (signaling support)
on slave to request for unicast transmission to master.
ipv6 multicastEnables IPv6 multicast as the transport method.
ipv6 unicast masterEnables IPv6 unicast master mode.
ipv6 unicast master negotiation-enableEnables unicast negotiation (signaling support)
on master to grant unicast transmission requests from slave.
ipv6 unicast slaveEnables IPv6 unicast slave mode.
ipv6 unicast slave negotiation-enableEnables unicast negotiation (signaling support)
on slave to request for unicast transmission to master.
layer2Enables Layer2 protocol (untagged or 802.1Q tagged Ethernet packet) as the transport
method.
layer2 address forwardableEnables the forwardable destination address
(01:1B:19:00:00:00) for the layer2 transport method.
layer2 address non-forwardableEnables the non-forwardable destination address
(01:80:C2:00:00:0E) for the layer2 transport method.
Defaults
None for the transport method.
Unicast negotiation is disabled for the unicast transport method.
Forwardable destination address is enabled for the Layer 2 transport method.
Command Mode INTERFACE CONFIGURATION

Usage
Information
For unicast transport, you must configure an IP address in INTERFACE mode or a source IP address
(in UNICAST IP CONFIGURATION mode) to represent the interface.
NOTE: If you are configuring PTP on an OS10 switch that functions as a virtual router, configure
the local IP address as the source IP address for unicast transport mode. Do not configure the
virtual IP address as the source IP address.
If you enable the unicast master mode, it leads to a sub mode where you can configure the slave IP
addresses.
