What were you trying to do that didn't work?
BC master port(ens2f1 in this case) and OC slave port(ens7f0 in this case) use different ptp_dst_ipv4 will let synchronize didn't work.
What is the impact of this issue to you?
bc clock won't synchronize with oc clock.
Please provide the package NVR for which the bug is seen:
linuxptp-4.2-3.el9.x86_64
How reproducible is this bug?: 100%
Steps to reproduce
1.
On GM clock the configuration as below
[root@dell-per740-51 ~]# cat gm.conf [global] clockClass 1 dataset_comparison G.8275.x G.8275.defaultDS.localPriority 128 logAnnounceInterval -3 logSyncInterval -4 logMinDelayReqInterval -4 summary_interval -4 network_transport UDPv4 [ens2f0] ptp_dst_ipv4 225.150.150.196 [root@dell-per740-51 ~]# ptp4l -E4Hmi ens2f0 --priority1=1 --domainNumber 22 -f gm.conf
2. On Bc site, the configuration as below
[root@dell-per750-11 ~]# cat bc.conf [global] clockClass 128 dataset_comparison G.8275.x G.8275.defaultDS.localPriority 128 logAnnounceInterval -3 logSyncInterval -4 logMinDelayReqInterval -4 summary_interval -4 network_transport UDPv4 [ens2f0] ptp_dst_ipv4 225.150.150.196 [ens2f1] ptp_dst_ipv4 225.149.149.197 [root@dell-per750-11 ~]# ptp4l -E4Hm -i ens2f0 -i ens2f1 --priority1=128 --domainNumber 22 -f bc.conf
3.On OC site, the configuration as below
[root@dell-per750-62 ~]# cat oc.conf [global] clockClass 254 dataset_comparison G.8275.x G.8275.defaultDS.localPriority 128 logAnnounceInterval -3 logSyncInterval -4 logMinDelayReqInterval -4 summary_interval -4 network_transport UDPv4 [ens7f0] ptp_dst_ipv4 225.149.149.197 [root@dell-per750-62 ~]# ptp4l -E4Hmi ens7f0 --priority1=254 --domainNumber 22 -f oc.conf
Expected results
On OC site, it can sync with BC master clock.
Actual results
OC clock still print sync timeout
