ptp sync-mechanism store-forward Sets the forwarding method of Sync
packets to store-forward.
To switch the forwarding mode over to straight forwarding, run the following command in global configuration
mode:
Command Purpose
ptp sync-mechanism
straight-forward
Sets the forwarding method of Sync
packets to store-forward.
37.3.4 Configuring the Domain Filtration Function
PTP devices can be classified through their domains for only PTP clocks in the same domain can exchange
PTP synchronization packets and PTP devices in different domains cannot conduct time synchronization.
After the domain filtration function is enabled, the PTP packets in other domains are dropped; if domain
filtration is disabled, TC will not conduct the domain checkup.
Before domain filtration, you have to set the domain in which the PTP port is located. Run the following
command in port mode:
Command Purpose
ptp domain number
Sets the domain to which the PTP port belongs. The
default domain of this port is domain0.
To configure the authentication mode, you also can run the following command in interface configuration
mode:
Command Purpose
ptp domain-filter
Enables domain filtration, which is enabled by default.
Run the following command in global mode to shut down domain filtration:
Command Purpose
no ptp domain-filter
Closes domain filtration.
37.3.5 Setting the Transmission Interval of Pdelay_Req Packets
During the path-delay process, you can set the transmission interval of Pdelay_Req packets.
Run the following command to configure the transmission frequency.
Command Purpose
ptp pdelay-interval time time stands for the transmission interval, which
ranges from -4 to 4. The actual transmission interval is
time powers of 2. For example, if time is 0, the actual
transmission interval is 1 second.
