asCapable is not being "seen" by the proxy

[christopher-s-hall]

You use this code to get the value of asCapable from PTP4L:

    case CMLDS_INFO_NP:
        if(pe.as_capable == ((CMLDS_INFO_NP_t *)data)->as_capable) {
            PrintDebug("Ignore unchanged as_capable");
            return;
        }
        pe.as_capable = \
            ((CMLDS_INFO_NP_t *)data)->as_capable > 0 ? true : false;
        //printf("as_capable = %d\n\n", pe.as_capable);
        break;

The problem is that PTP4L never pushes this notification. The result is that asCapable in the proxy/client is always false. There must be subscription option that includes this and the code in port.c needs to push this through port_notify_event() when asCapable changes

Hi @christopher-s-hall,

We subscribe the event through d.setEvent(NOTIFY_CMLDS), and we do see jclk_proxy is receiving CMLDS_INFO_NP notification message.

On ptp4l side, we set follow_up_info to 1 and keep asCapable as its default value, which is 'auto'.

This is the snapshot of result when master is present:

This is the snapshot of result when master is terminated:

Is this what you are asking for?

Looking on LinuxPTP port.c

After subscribing with d.setEvent(NOTIFY_CMLDS), I see the calling of port_notify_event(p, NOTIFY_CMLDS);
In int port_capable(struct port *p) which is called to update the asCapable with a CMLDS_INFO_NP message.
However if p->delayMechanism == DM_COMMON_P2P,
which is defined with setting delay_mechanism to COMMON_P2P in the configuration.
Then the updating accoutre in port_peer_delay(struct port *p) after receiving pdelay from peer.
@christopher-s-hall,
Did you use the COMMON_P2P configuration?
