o For trunk ports, Ingress Filtering is not
allowed to be changed from enabled;
o For trunk ports, Ingress Acceptance is
not allowed to be changed from Tagged
and Untagged;
o Egress tagging should be chosen as
Untag Port VLAN;
o Allowed VLANs should be 1, 10, 20, 30;
o No forbidden VLANs should be
configured.
 Switch configuration where IED Receiving only GOOSE is connected
o Port where IED Receiving only GOOSE is connected:
This port will receive untagged and tagged frames and send untagged frames, only
used by management software communication. Thus, IED Receiving only GOOSE
configuration ports should have the following characteristics:
 VLAN Identifier Ingress process: untagged frames would
be forwarded to the Port VID VLAN, and tagged frames
are not expected. Thus, tagged frames can be if to be
forwarded to the VLAN that is embedded at the frame;
 Filtering ingress process: this port should accept both
untagged and tagged frames, but there is a critical point
on Sampled Values messages on that port. Thus, it is
desirable to set Sampled Values VLAN as forbidden;
 Egress process: egress process should be set to Untag all
frames, as this equipment cannot understand VLAN
information.
Thus, configuration of the port where the IED Receiving only GOOSE is connected
should be as follows.
o Port mode should be chosen as Hybrid
port;
o Port VLAN should be 1;
o Port Type should be chosen as C-Port;
o Ingress Filtering should be disabled;
o Ingress Acceptance should be chosen
as Tagged and Untagged;
o Egress tagging should be chosen as
Untag All;
o Allowed VLANs should be 1, 10;
o Forbidden VLANs should be 20.
