Pass flow
control
packet
R/W
= 1, switch will not filter 802.1x “flow control” packets
0x0
2
Buffer share
mode
R/W
= 1, buffer pool is shared by all ports. A port can use more buffer
when other ports are not busy.
= 0, a port is only allowed to use 1/3 of the buffer pool
0x1

Link change
age
R/W
= 1, link change from “l(fā)ink” to “no link” will cause fast aging
(<800us) to age address table faster. After an age cycle is
complete, the age logic will return to normal (about 200
seconds).
Note: If any port is unplugged, all addresses will be automatically aged
out.

Pass all
frames
R/W
= 1, switch all packets including bad ones. Used solely for
debugging purposes. Works in conjunction with Sniffer
mode only.

R/W
= 0, normal mode

IEEE 802.3x
Transmit
direction flow
control
enable
R/W
= 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.

IEEE 802.3x
Receive
direction flow
control
enable
R/W
= 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.
1
3
Frame
Length field
check
R/W
= 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).
0
2
Aging enable
R/W
= 1, enable age function in the chip
= 0, disable age function in the chip
1
Fast age
enable
R/W
= 1, turn on fast age (800 us)
0
Aggressive
back off
enable
R/W
= 1, enable more aggressive back off algorithm in half duplex
mode to enhance performance. This is not an IEEE
standard.
