this section so that all “send to CPU conditions” are described together in one section (e.g. OAM BIDs, In-band
VCCV, “CPU Debug RXP PW Bundle” and error condition Discard Switches).
9.3.2.3.1
When an Ethernet packet is received with the Ethernet Broadcast Destination Address (DA) and the packet
includes one of the PW Header Types, the
CPU (0) or Discarded (1).
When an Ethernet packet is received with the Ethernet Broadcast DA and the packet doe not include one of the PW
Header Types, the
9.3.2.3.2
When an Ethernet packet is received and the packet includes an Ethernet DA that is not recognized (not equal to
PC.CR7
to determine whether the packet is forwarded to the CPU (0) or Discarded (1). Packets with the Ethernet Broadcast
DA are regarded as having a “known” address and are not affected by the
If the Ethernet DA registers are not programmed
combined settings of PC.CR1.DPS9,
Ethernet packets that do not use the “0” DA value are forwarded to the CPU (0) or Discarded (1).
9.3.2.3.3
When a packet is received with a recognized PW Header (MEF-8, MFA-8, UDP or L2TPv3) but the received PW-ID
does not match any of the programmed BIDs or OAM BIDs, the
packet is forwarded to the CPU (0) or Discarded (1).
9.3.2.3.4
MEF OAM Ethernet Type packets are recognized when the received Ethernet Type field is equal to the
programmed PC.CR4.MOET. The

When an Ethernet packet is received with an Ethernet Type field that is equal to PC.CR20.CDET, the

9.3.2.3.7
When an ARP packet is received (Ethernet Type = 0x0806) with an IP Destination Address that is not equal to one
of the IPv4 addresses programmed at
packet is forwarded to the CPU (0) or Discarded (1).

When an Ethernet packet is received with an Ethernet Type field that is not recognized (not equal to ARP, Unicast
MPLS, Multicast MPLS, IPv4, IPv6, PC.CR20.CDET,
