Specifying The Protocol For Encapsulating Ptp Messages As Udp (Ipv4); Specifying The Source Ip Address For Udp Packets; Configuring The Delay Correction Value - HP 5920 Configuration Manual

Specifying the protocol for encapsulating PTP messages as UDP
(IPv4)
PTP messages can be encapsulated in IEEE 802.3/Ethernet packets or UDP packets.
To configure the protocol for encapsulating PTP messages as UDP (IPv4):
Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface view or Layer 3
Ethernet interface view.
3. Configure the protocol for
encapsulating PTP messages
as UDP (IPv4).

Specifying the source IP address for UDP packets

Step
1. Enter system view.
2. Enter interface view.

Configuring the delay correction value

PTP performs time synchronization based on the assumption that the delays in sending and receiving
messages are the same. However, this is not practical. If you know the offset between the delays in
sending and receiving messages, you can configure the delay correction value for more accurate time
synchronization.
To configure the delay correction value for every clock node:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface view or Layer 3
Ethernet interface view.
3. Configure delay correction
value.

Remarks
N/A
N/A
By default, PTP messages are
encapsulated in IEEE
802.3/Ethernet packets.
Remarks
N/A
By default, no source IP address is
specified for PTP messages
encapsulated in UDP packets.
Remarks
N/A
N/A
Optional.
The default is 0 nanoseconds,
which means delay correction is
not performed.
