Description
CR2.
A:0304h
Configuration Register 2. Default: 0x00.00.00.00
UPVC1
[31:16] rwc-_-_
UDP Protocol Value Constant 1 is used to compare against each received UDP
Protocol Type field when UPVCE = 1 (1 of 2 recognized UDP Protocol Types).
UPVC2
[15:0] rwc-_-_
UDP Protocol Value Constant 2 is used to compare against each received UDP
Protocol Type field when UPVCE = 1 (1 of 2 recognized UDP Protocol Types).
CR3.
A:0308h
Configuration Register 3. Default: 81.00.81.00h
VOTPID
[31:16] rwc-_-_
VLAN Outer Tag Protocol ID specifies the Outer VLAN TPID value that is
accepted when a packet header also includes an Inner VLAN Tag with TPID =
PC.CR3.VITPID.
VITPID
[15:0] rwc-_-_
VLAN Inner Tag Protocol ID specifies the Inner VLAN TPID value that is
accepted when a packet includes 1 or 2 VLAN Tags. The common VITPID value
that is used is 0x8100.
CR4.
A:030Ch
Configuration Register 4. Default: 0x00.00.00.00
MET
[31:16] rwc-_-_
MEF Ether Type programs the Ethernet Type field value for the MEF-8 protocol.
The IANA assigned Ethernet Type value for MEF is 0x88D8. Some systems may
otherwise use Ethernet Type = 0x8847.
MOET
[15:0] rwc-_-_
MEF OAM Ether Type programs the Ethernet Type field value for the MEF OAM
protocol.
CR5.
A:0310h
Configuration Register 5. Default: 0x00.00.00.00
VOM
[31:16] rwc-_-_
VCCV OAM Mask programs the mask of the 16 most significant bits of the
Control Word that is used to identify In-band VCCV OAM packets (“1” = VOV bit is
tested/enabled, one bit mask for each of the 16 VOV bits).
VOV
[15:0] rwc-_-_
VCCV OAM Value programs the value of the 16 most significant bits of the
Control Word that are used to identify an In-band VCCV OAM packet. The VOM
bits can be used to ignore any of these 16 bits. To use the most common In-band
VCCV identifier, program VOV = 0x1000 and VOM = 0xF000.
CR6.
A:0314h
Configuration Register 6. Default: 0x00.00.00.00
IV4A1
[31:0] rwc-_-_
IPv4 Address 1 programs the 32-bit value for the first IPv4 Destination Address.
CR7.
A:0318h
Configuration Register 7. Default: 0x00.00.00.00
IV4A2
[31:0] rwc-_-_
IPv4 Address 2 programs the 32-bit value for the 2nd IPv4 Destination Address.
CR8.
A:031Ch
Configuration Register 8. Default: 0x00.00.00.00
IV4A3
[31:0] rwc-_-_
IPv4 Address 3 programs the 32-bit value for the 3rd IPv4 Destination Address.
CR9.
A:0320h
Configuration Register 9. Default: 0x00.00.00.00
IV6A1A
[31:0] rwc-_-_
IPv6 Address 1 A-bits programs bits 0 to 31 of the 1st 128-bit IPv6 Destination
Address.
CR10.
A:0324h
Configuration Register 10. Default: 0x00.00.00.00
IV6A1B
[31:0] rwc-_-_
IPv6 Address 1 B-bits programs bits 32 to 63 of the 1st 128-bit IPv6 Destination
Address.
CR11.
A:0328h
Configuration Register 11. Default: 0x00.00.00.00
IV6A1C
[31:0] rwc-_-_
IPv6 Address 1 C-bits programs bits 64 to 95 of the 1st 128-bit IPv6 Destination
Address.
CR12.
A:032Ch
Configuration Register 12. Default: 0x00.00.00.00
IV6A1D
[31:0] rwc-_-_
IPv6 Address 1 D-bits programs bits 96 to 127 of the 1st 128-bit IPv6 Destination
Address.
CR13.
A:0330h
Configuration Register 13. Default: 0x00.00.00.00
IV6A2A
[31:0] rwc-_-_
IPv6 Address 2 A-bits programs bits 0 to 31 of the 2nd 128-bit IPv6 Destination
Address.
