This port will receive untagged frames and send untagged and tagged frames from PTP VID, as Grandmaster Clock will
multicast PTP messages. In addition, management software will communicate with the equipment in that port. Thus, PTP
Grandmaster clock configuration ports should have the following characteristics:

Thus, configuration of the port where the PTP Grandmaster Clock is connected
should be as follows.
o
This port will receive untagged and tagged frames and send tagged and untagged
frames from many VID, as all traffic from switches should traffic at these ports. Thus,
configuration of these ports should have the following characteristics:

VLAN Identifier Ingress process: untagged
frames would be forwarded to the Port VID VLAN,
and tagged frames are forwarded to the VLAN
that is embedded at the frame;

Filtering ingress process: this port should
accept untagged frames;

Egress process: egress process should be set to
Untag only frames with Port VLAN identifier.
Port mode should be chosen as Trunk
