Bit 4-5: LAN No Priority Tag Detected Forwarding (LNPDF[2:1]). Enabled for each port with SU.LP1C.LP1PF
or SU.LP2C.LP2PF. Controls how frames are handled when the received frame does not contain DSCP, does not
contain a VLAN Tag, or the 13
action is applied to both Ethernet ports.
Bit 0-3: LAN No VLAN Tag Detected Forwarding (LNVDF[4:1]). Enabled for each port with SU.LP1C.LP1ETF or
SU.LP2C.LP2ETF. Controls how frames are handled when the received frame does not contain a VLAN tag or the
