Description
Packet_classifier_cfg_reg6.
Relevant only for packets received from Ethernet port.
Packet_classifier_cfg_reg3 0x44
Bits Data Element Name R/W
Reset
Value
Description
[31:29] Reserved - 0x0 Must be set to zero
[28]
Discard_packet_length_
mismatch
R/W 0x0 Must be set to zero
[27] Ip_udp_bn_loc R/W 0x0
0 = Bundle identifier is located in the source UDP port
number field in IP/UDP packets
1 = Bundle identifier located in the destination UDP port
number field in IP/UDP packets
See section 10.6.13.2.
[26:25] TDMoIP_port_num_loc R/W 0x0
Used for UDP only:
00 =
3Packet_classifier_cfg_reg4.TDMoIP_port_num1/2 is
ignored (no checking is performed)
01 = TDMoIP_port_num1/2 should be compared to the
source UDP port number field in IP/UDP packets
10 = TDMoIP_port_num1/2 should be compared to the
destination UDP port number field in IP/UDP packets
11 = Reserved
See section 10.6.13.1.
[24] Discard_switch_8 R/W 0x0
Packets with Ethertype = CPU_dest_ether_type. See
section 10.6.13.
0 =
Forward to CPU
1 = Discard
[23] Discard_switch_7 R/W 0x0
TDMoP OAM packets. See section 10.6.13.
0 =
Forward to CPU
1 = Discard
[22] Discard_switch_6 R/W 0x0
TDMoP packets whose Rx_Bundle_Identifier doesn’t
match any of the chip’s assigned bundle numbers or OAM
bundle numbers. See section 10.6.13.
0 = Forward to CPU
1 = Discard
[21] Discard_switch_5 R/W 0x0
IP/UDP packets whose UDP destination/source port
number is different from 3Packet_classifier_cfg_reg4.
TDMoIP_Port_Num1 or 2. See section 10.6.13.
0 =
Forward to CPU
1 = Discard
See TDMoIP_port_num_loc abov
e.
[20] Discard_switch_4 R/W 0x0
IP packets whose IP protocol field is different from UDP or
L2TPv3. See section 10.6.13.
0 =
Forward to CPU
1 = Discard
[19] Discard_switch_3 R/W 0x0
ARP packets whose IP destination address matches one
of the chip’s IPv4 addresses. See section 10.6.13.
0 =
Forward to CPU
1 = Discard
[18] Discard_switch_2 R/W 0x0
Packets with Ethertype different from IP, MPLS or ARP.
See section 10.6.13.
0 =
Forward to CPU
1 = Discard
[17] Discard_switch_1 R/W 0x0
IP packets whose IP destination address does not match
chip’s IP addresses. See section 10.6.13.
0 =
Forward to CPU
1 = Discard
