Bit [5]:
Bit [6]:
Bit [7]:
(Group 2 Address) Port Trunking Groups
Bits [3:0]
Bits [7:4]
TRUNKn– Trunk Group 0~7
TRUNKn_HASH10 – Trunk group n hash result 1/0 destination port number
Disable IEEE multicast control frame (01-80-C2-00-00-00 to 01-80-C2-00-00-FF) to
CPU in managed mode. In unmanaged mode, frame is forwarded as multicast (except
PAUSE frame).
0: Frame is forwarded to CPU (Default)
1: Frame is forwarded as multicast (except PAUSE frame)
IP Multicast Enable
0: Disable (default)
1: Enable
In general, this bit is equal to ^FEN[4].
Enable logical port match in secure mode
0: Disable (Default)
1: Enable - When Well Known or User Define logical port force discard enabled, force
any IP packet with logical port number matching logical port numbers to CPU.
Hash result 0 destination port number (Default 0)
Hash result 1 destination port number (Default 0)
