Hi Venkata,

That functionality isn’t available at this time. The ptp service-parameter values are only used to populate the global section of the ptp4l conf. The service-parameter values are system wide, but the ptp interface configurations are host specific, particularly in a multinode system.

Subject: [Starlingx-discuss] PTP4L configuration in StarlingX for custom sections

[Please note: This e-mail is from an EXTERNAL e-mail address]

Hi

We are running an STX4.0/Simplex load and like to understand how we can add custom sections for PTP related configurations

We leverage “system service-parameter-add” to modify the parameters of existing sections in /etc/ptp4l.conf (for e.g. global section which is already there) but how do we add a new section. We tried to use “system service-parameter-add” and use the ‘—resource’ field to update this but it doesn’t get reflected in ptp4l.conf (even after running the apply command)

For e.g. we want to add a section like below in bold below

global]
dataset_comparison G.8275.x
G.8275.defaultDS.localPriority 128
#maxStepsRemoved 255
logAnnounceInterval -3
logSyncInterval 0
logMinDelayReqInterval 0
masterOnly 0
slaveOnly 1
G.8275.portDS.localPriority 128
hybrid_e2e 1
inhibit_multicast_service 1
unicast_listen 1
unicast_req_duration 60
domainNumber 44
step_threshold 0.0
first_step_threshold 0.00002
#announceReceiptTimeout 8
tx_timestamp_timeout 50
#
# Customize the following for slave operation:
#
[unicast_master_table]
table_id 1
logQueryInterval 2
UDPv4 192.168.2.100
#
[enp134s0f1]
unicast_master_table 1

network_transport UDPv4

We tried this with no luck (although it gets added to system service-parameter-list)
