Description

0
RW
Pass all frames
1 = switch all packets including bad ones. Used solely for debugging
purposes. Works in conjunction with Sniffer mode only.
14
0
RW
Reserved.
For factory test purposes only. Always write 0.
13
1
RW
IEEE 802.3x Transmit direction flow control enable
1 = will enable transmit direction flow control feature.
0 = will not enable transmit direction flow control feature. Switch will not
generate any flow control packets.
12
1
RW
IEEE 802.3x Receive direction flow control enable
1 = will enable receive direction flow control feature.
0 = will not enable receive direction flow control feature. Switch will not
react to any received flow control packets.
11
1
RW
Frame Length field check
1 = will check frame length field in the IEEE packets. If the actual length
does not match, the packet will be dropped (for Length/Type field < 1500).
10
1
RW
Aging enable
1 = enable age function in the chip
0 = disable age function in the chip
9
0
RW
Fast age enable
1 = turn on fast age (800s)
8
0
RW
Aggressive back off enable
1 = enable more aggressive back off algorithm in half duplex mode to
enhance performance. This is not an IEEE standard.

Pass flow control packet
1 = switch will not filter 802.1x “flow control” packets.

Link change age
1 = link change from “l(fā)ink” to “no link” will cause fast aging (<800s) to
age address table faster. After an age cycle is complete, the age logic will
return to normal (300 + 75 seconds).
Note: If any port is unplugged, all addresses will be automatically aged
out.
