1: Perform ‘local loopback’, i.e. loop back MAC’s RX back to TX
0: Normal operation

1: The switch will replace a NULL VID with a port VID (12 bits)
0: No replacement for a NULL VID
25.3
1: If the received packets are tagged, the switch will discard packets whose
VID does not match the ingress port’s PVID
0: No packets will be dropped

1: Disable 802.1p priority classification for ingress packets on port 1
0: Enable 802.1p priority classification
25.1
1: Disable Diffserv priority classification for ingress packets on port 1
0: Enable Diffserv priority classification
