12.3.5 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 03 (2011-12-29)
The interval for sending Announce packets on an interface is set to the announce-
intervalth power of 2, in milliseconds.
The default value of announce-interval is 7, which means that the interval for sending
Announce packets on the interface is 128 ms.
4. (Optional) Run:
ptp announce-receipt-timeout timeout-value
The timeout period for receiving Announce packets on an interface is set to the nth
power of 2, in milliseconds, where n is specified by timeout-value.
The default timeout-time is 9, which means that the timeout period for receiving
Announce packets on the interface is 512 ms.
Configuring time attributes for Delay packets
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 min-req-interval interval-value
The interval for sending PdelayReq packets and DelayReq packets on an interface is
set to the interval-valueth power of 2, in milliseconds.
The default interval-value is 7, which means that the interval for sending PdelayReq
packets and DelayReq 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.
