Description
Stop SA learning 0: enable SA learn
→
blocking state, only do the forwarding to CPU, and no
learning, and no transmitting (except the packet from
CPU) 0: normal state, 1: block state
→
If in blocking state
→
to CPU, 0: forward all packets to CPU
Not Applicable
port aging:
1: enable aging,
0: disable aging that the MAC address is belong to
programmed port(s)
SA secured mode:
0: don't care SA match,
1: the pakcets' SA need match, otherwise discard the
packets
Note:
1. set Dis_Learn and SA_secured at the same
time, then only forward the packets with the
SA and port number matched.
2. 2. set SA_secured only, then no any secured
function
Description
MII port AN monitor enable:
1: enable MII AN monitor via MDIO (if in the dumb
mode, set to 1),
0: disable
Force MII port speed if AN monitor disable:
00: forced in 10M
01: forced in 100M
10: forced in giga
11: reserved
Force MII port duplex if AN monitor disable:
0: forced in half duplex
1: forced in full duplex.
Note: duplex is forced in full, if speed is forced in the
giga
disable:
