Hi, I try use grand master clock working with ptpv2 G.8265.1 as clock source in my Linux using ptp4l. Unfortunately I cannot config it properly. Could you look into my configuration and logs and give me some advice where can I start? Information about Grand Master clock that I got: Grand master uses G8265.1 standard which is a L3 unicast frequency synchronization source. IP: 10.133.1.2 Doamin Number = 4. Announce interval = 1 every 2 sec Sync Interval = 128 sync messages per sec delay request interval = 128 request messages per sec My configuration file for ptp4l: [global] masterOnly 0 hybrid_e2e 1 inhibit_multicast_service 1 unicast_listen 1 unicast_req_duration 60 domainNumber 4 # [unicast_master_table] table_id 1 logQueryInterval 1 UDPv4 10.133.1.2 peer_address 10.133.1.2 [enp3s0f0]
