Duplicate Packet Detect Enable.
0 = Duplicate Packet Detect function is disabled
1 = Discard duplicate packet for Bundle used for clock recovery (BCDR4.PCRE)
2 = reserved
3 = Discard duplicate packets for all SAT/CES/HDLC Bundle types
RSVD
[29:26]
Reserved.

Discard Packet Switch 10. Discard packets with too many MPLS Labels.
0 = Forward MPLS packets with > 3 MPLS labels to CPU (> 2 outer labels)
1 = Discard those packets.
DPS9
[24] rwc-_-_
Discard Packet Switch 9. Discard packets with unknown Ethernet DA.
0 = Forward packets with unknown Ethernet DA to CPU (PC.CR17 – PC.CR19)
1 = Discard those packets.
DPS8
[23] rwc-_-_
Discard Packet Switch 8. Discard packets with Ethernet type = CPU Destination.
0 = Forward packets with Ethernet type = PC.CR20.CDET to CPU (CPU Dest.)
1 = Discard those packets.
DPS7
[22] rwc-_-_
Discard Packet Switch 7. Discard OAM packets.
0 = Forward MEF OAM, OAM BID and enabled In-band VCCV packets to CPU.
1= Discard those packets.
DPS6
[21] rwc-_-_
Discard Packet Switch 6. Discard PW packets with Unknown PWID.
0 = Forward packets to CPU that have any PW header and includes a PWID
that does not match any of the programmed BIDs or OAM BIDs
1 = Discard those packets.
DPS5
[20] rwc-_-_
Discard Packet Switch 5. Discard UDP PW packets with wrong UDP Protocol.
0 = Forward UDP packets to CPU that have a recognized BID or OAM BID but
have an unexpected UDP Protocol Type (Protocol ≠ PC.CR2.UPVC1 or
PC.CR2.UPVC2, and PC.CR1.UPVCE = 1). The UDP Protocol Type may
be in the UDP Destination or Source Port position (set using
B.BCDR4.RXUBIDLS, PC.CR1.UBIDLS and PC.CR1.UBIDLCE).
1 = Discard those packets.
DPS4
[19] rwc-_-_
Discard Packet Switch 4. Discard IP packets that do not have PW headers.
0 = Forward IP packets with unknown IP Protocol to CPU (not UDP or L2TPv3)
1 = Discard those packets.
DPS3
[18] rwc-_-_
Discard Packet Switch 3. Discard ARP packets with a recognized IPv4 DA.
0 = Forward ARP packets with a recognized IPv4 DA to CPU (PC.CR6-PC.CR8)
1 = Discard those packets.
DPS2
[17] rwc-_-_
Discard Packet Switch 2. Discard packets with unknown Ethernet Type.
0 = Forward packets to CPU that have an unknown Ethernet Type (not IPv4,
IPv6, MPLS Unicast, MPLS Multi-cast, ARP, MEF = G.CR4.MOET, MEF
OAM G.CR4.MET or CPU Destination Ethernet Type = G.CR20.CDET).
1 = Discard those packets.
DPS1
[16] rwc-_-_
Discard Packet Switch 1. Discard IP packets with unknown IP DA.
0 = Forward IP packets with unknown IP DA to CPU (not PC.CR6 - PC.CR16)
1 = Discard those packets.
DPS0
[15] rwc-_-_
Discard Packet Switch 0. Discard ARP packets with an unknown IPv4 DA.
0 = Forward ARP packets with unknown IP DA to CPU (not PC.CR6 – PC.CR8)
1 = Discard those packets
