Comments
The S132 can recognize up to 2 programmed Ethernet DAs.
TDMoP packets with the Broadcast DA: continue processing (0) or discard(1)
Non-TDMoP packets with the Broadcast DA: continue processing (0) or discard(1)
Packets with DA ≠ DA1, DA2 or Broadcast DA: send to CPU (0) or discard (1)
Packets with 1 or 2 VLAN Tags must use this TPID in the Inner Tag position.
Packets with 2 VLAN Tags must use this TPID in the Outer Tag position.
Packets with unknown Ethernet Type: send to CPU (0) or discard (1)
Select “Only IPv4” (0x1), “Only IPv6” (0x3) or “both IPv4 and IPv6” (0x0)
The S132 can recognize up to 3 CPU configured IPv4 DAs.
The S132 can recognize up to 2 CPU configured IPv6 DAs.
Send to CPU (0) or Discard (1).
Packets with unknown IP Protocol: send to CPU (0) or discard (1)
Ignore Bad Checksum and Forward pkt (0) or Discard pkt (1).
PW packets with unknown PW-ID: send to CPU (0) or discard (1)
Send to CPU (0) or Discard (1) MEF OAM, In-band VCCV and OAM BIDs
Identify pkt with this Ether Type as a MEF-8 TDMoP pkt. Default = 0x88D8.
Identify pkt with this Ether Type as a MEF-8 OAM (CPU) pkt.
Send to CPU (0) or Discard (1).
0 = Test UDP pkt for 16-bit BID based on UBIDLCE setting and test UDP pkt for
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
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
UDP BID/OAM BID bit Mask (0 = ignore bit; 1 = test bit; 0xFFFF = test all bits)
0 = Ignore UDP Protocol Type
1 = Process UDP pkt with BID but UDP Protocol ≠ UPVC1/2 according to DPS5
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
For UDP pkt with a checksum error: Ignore checksum (0) or Discard packet (1).
UDP Protocol Type values for when UPVCE is enabled (default 0x085E).
Send to CPU (0) or Discard (1) ARP packets with known IPv4 DA.
Send to CPU (0) or Discard (1) ARP packets with unknown IPv4 DA.
Identify pkt with this Ether Type as CPU Destination Ethernet Type.
Send to CPU (0) or Discard (1) packets with CPU Destination Ethernet Type
16-bit OAM BID in either UDP Source or Destination Port location
