8.3.5 Configuring Encapsulation Types for PTP Packets

Prerequisite
Before configuring encapsulation modes for 1588v2 packets, check the link type for 1588v2
packet transmission:
l
l
Context
By default, the MAC encapsulation mode is used.
Procedure
l
Issue 01 (2010-12-15)
The default interval-value is 7, which means that the interval for sending PdelayReq
packets and DelayReq packets packets on the interface is 128 ms.
The Layer 2 link adopts the MAC encapsulation mode for 1588v2 packets.
The Layer 3 link adopts the UDP encapsulation mode for 1588v2 packets.
NOTE
The encapsulation modes of 1588v2 packets sent from interfaces of devices enabled with time
synchronization must be the same. If different encapsulation modes are used, devices cannot interwork.
Configuring the MAC encapsulation mode
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
3. (Optional) Run:
ptp mac-egress destination-mac destination-mac
The 1588v2 packets to be sent from the interface is encapsulated in MAC
encapsulation mode, and the destination MAC address is configured.
– For unicast MAC encapsulation
Specify the unicast destination MAC address encapsulated in the 1588v2 packet
in the interface view.
– For multicast MAC encapsulation
A default multicast destination MAC address is adopted, which means that
destination-MAC destination-MAC command does not need to be performed. The
default multicast destination MAC address varies with delay measurement
mechanisms as shown in the following table.
