Default
Register 2 (0x02): Global Control 0 (continued)
2
Buffer share mode
1 = buffer pool is shared by all ports. A port can use
R/W
0x1
more buffer when other ports are not busy.
0 = a port is only allowed to use 1/5 of the buffer pool.
1
UNH mode
1 = the switch will drop packets with 0x8808 in T/L
R/W
0
filed, or DA=01-80-C2-00-00-01.
0 = the switch will drop packets qualified as
“flow control” packets.
0
Link change age
1 = link change from “l(fā)ink” to “no link” will cause fast
R/W
0
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.
Register 3 (0x03): Global Control 1
7
Pass all frames
1 = switch all packets including bad ones. Used solely
R/W
0
for debugging purpose. Works in conjunction with
sniffer mode.

Frame length field
1 = will check frame length field in the IEEE packets.

If the actual length does not match, the packet will be
dropped. (for L/T < 1500)
