Ethernet
CR17 - CR19
Ethernet DA1 and DA2
The S132 can recognize up to 2 programmed Ethernet DAs.
CR1.DBTP
Broadcast TDMoP Pkt Discard
TDMoP packets with the Broadcast DA: continue processing (0) or discard(1)
CR1.DBCP
Broadcast CPU Pkt Discard
Non-TDMoP packets with the Broadcast DA: continue processing (0) or discard(1)
CR1.DPS9
Unknown Ethernet DA Discard
Packets with DA ≠ DA1, DA2 or Broadcast DA: send to CPU (0) or discard (1)
CR3.VITPID
VLAN Inner Tag Protocol ID
Packets with 1 or 2 VLAN Tags must use this TPID in the Inner Tag position.
CR3.VOTPID
VLAN Outer Tag Protocol ID
Packets with 2 VLAN Tags must use this TPID in the Outer Tag position.
CR1.DPS2
Unknown Ethernet Type
Discard
Packets with unknown Ethernet Type: send to CPU (0) or discard (1)
IPv4 & IPv6
CR1.RXPIVS &
CR1.RXPDSD
IP Version
Select “Only IPv4” (0x1), “Only IPv6” (0x3) or “both IPv4 and IPv6” (0x0)
CR6 - CR8
IPv4 Destination Address 1 - 3
The S132 can recognize up to 3 CPU configured IPv4 DAs.
CR9 – CR16

MPLS
CR1.DPS10
>2 MPLS Outer Label Discard
Send to CPU (0) or Discard (1).
UDP1
CR1.UBIDLS
UDP BID Global Location
Select
0 = Test UDP pkt for 16-bit BID based on UBIDLCE setting and test UDP pkt for
16-bit OAM BID in either UDP Source or Destination Port location
1 = Test UDP pkt for 16-bit BID/OAM BID match in UDP Destination Port
2 = Test UDP pkt for 16-bit BID/OAM BID match in UDP Source Port
3 = Test UDP pkt for 32-bit BID/OAM BID match in Source and Dest. Port
CR1.UBIDLCE
UDP BID per-Bundle Location
Select (only for UBIDLS=0)
0 = Auto detect = Test UDP pkt for 16-bit BID match in UDP Source or Dest. Port
1 = Test UDP pkt for 16-bit BID in UDP Port selected by B.BCDR4.RXUBIDLS
CR20.UBIDM
UDP BID Mask
UDP BID/OAM BID bit Mask (0 = ignore bit; 1 = test bit; 0xFFFF = test all bits)
CR1.UPVCE
UDP Protocol Check En
(valid for UBIDLS ≠ 3)
0 = Ignore UDP Protocol Type
1 = Process UDP pkt with BID but UDP Protocol ≠ UPVC1/2 according to DPS5
CR1.DPS5
Unknown UDP Protocol Type
Discard (valid for UPVCE = 1)
0 = Send to CPU, UDP pkt with BID but UDP Protocol ≠ UPVC1/2
1 = Discard UDP pkt with BID match but UDP Protocol ≠ UPVC1/2
CR1.DUCPE
UDP Checksum Error
For UDP pkt with a checksum error: Ignore checksum (0) or Discard packet (1).
CR2.UPVC1 &
CR2.UPVC2
UDP Protocol Type 1 - 2
UDP Protocol Type values for when UPVCE is enabled (default 0x085E).

CR1.DPS3
ARP with Known IP DA
Send to CPU (0) or Discard (1) ARP packets with known IPv4 DA.
CR1.DPS0
ARP with Unknown IP DA
Send to CPU (0) or Discard (1) ARP packets with unknown IPv4 DA.
CPU Destination Ethernet Type
CR20.CDET
MEF OAM Ether Type
