value

01H

Half duplex control

Bit [0]: Drops the packet that encounters 16 successive collisions.

1: Drop; 0: Forward

Bit [1]: Collision back off.

1: Disable; 0: Enable

Bit [2]: Reserved and should be set to “0”.

Bit [3]: Broadcast BPDU packet.

1: Broadcast; 0: Drop

Bit [4]: Reserved and should be set to “0”.

Bit [15]~ Bit 5: Not used.

R/W

5’h0A

02H

Network configuration packet capture:

Bit [0]: Spanning tree.

1: Capture & forward to the CPU port.

0: Drop.

Bit[1]: In-band management packet(Destinatopn MAC Address

=This Switch MAC Address)

1: Capture & forward to the CPU port.

0: Drop

Note:

If this bit is set to “1”, the ARP will be sent to CPU port too.

Bit[2]: LACP

Only forward to the CPU port when register1 bit[3]= 0.

Braodcast to other ports when register1 bit[3]=1

0: Drop

Bit[3]: GVRP

1: Capture & forward to the CPU port only .

0: Broadcast

IP packet capture

Bit[5:4] : ICMP

Bit[7:6] : IGMP

Bit[9:8] : TCP

Bit[11:10] : UDP

Bit[13:12] : OSPF

Bit[15:14] : Others

00 : Send to port 1 ~ port 16 only

01 : Send to port 18(CPU) and port 1 ~ port 16

10 : Send to port 18(CPU) only

Note:

1. When the packet capture function is enabled, port 18 should be

set to as CPU port.

2. If only one CPU port is required, it’s recommedded to set port 18

as the CPU port.
