This along with the previous register determines how
many “64 byte blocks” of packet data are allowed on an
input port in a preset period. The period is 50ms for
100BT or 500ms for 10BT. The default is 1%.
N/A Don’t change.
Description
1, will do Rx AND Tx sniff (both source port and
destination port need to match).
0, will do Rx OR Tx sniff (Either source port or
destination port needs to match).
This is the mode used to implement Rx only sniff.
1, enable half-duplex back pressure on switch
MII/RMII interface.
0, disable back pressure on switch MII interface.
1, enable MII/RMII interface half-duplex mode.
0, enable MII/RMII interface full-duplex mode.
1, enable full-duplex flow control on switch MII/RMII
interface.
0, disable full-duplex flow control on switch MII/RMII
interface.
1, the switch SW5-MII/RMII is in 10Mbps mode.
0, the switch SW5-MII/RMII is in 100Mbps mode.
1, will replace null VID with port VID (12 bits).
0, no replacement for null VID.
This along with the next register determines how many
“64 byte blocks” of packet data allowed on an input
port in a preset period. The period is 50ms for 100BT
or 500ms for 10BT. The default is 1%.
