PTP IEEE1588 CRS326-24S+2Q+ Slave mode

RouterOS General
1

Hi,

I have CRS326-24S+2Q+, FW 7.11.3.
It has PTP GM Videotek VSG-4MTG on sfp-sfpplus9 port.
I do see incoming PTP from GM on this port via PacketSniffer streaming.

GM runs with IEEE1588 profile:
e2e, PTP over UDP
DomainNumber 1
Priority1 126
Priority2 112.

Whenever I create PTP and bind the port after a while CRS326 sets itself as GM instead of slave.

[admin@MikroTik] > /system ptp add name=ptp3 delay-mode=e2e transport=ipv4 priority1=247
[admin@MikroTik] > /system ptp port add interface=sfp-sfpplus9 ptp=ptp3

What am I doing wrong?

Thank you in advance,
rysiekg

After updating to 7.14RC works

Reply here because I read somewhere that you have an issue with IGMP & PTP enbled together.

I found a workaround

When IGMP is enabled, the dynamic MDB Entry 224.0.1.129 (the Multicast group related to PTP) does not include the bridge…
I tried to make a static MDB entry, including all my ports related to PTP and include the bridge. Bingo.. the PTP BC is locking to my GM and correctly acts as BC for my slaves devices… with IGMP enabled.
