Description
Mode
Default
Buffer share mode
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 1/5 of the buffer pool.
1 = the switch will drop packets with 0x8808 in T/L
filed, or DA=01-80-C2-00-00-01.
0 = the switch will drop packets qualified as
“flow control” packets.
1 = link change from “l(fā)ink” to “no link” will cause fast
aging (<800
s) 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.

Pass all frames
1 = switch all packets including bad ones. Used solely
for debugging purpose. Works in conjunction with
sniffer mode.

Note: Bit 5 and bit 4 default values are controlled by
the same pin, but they can be programmed
independently.

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 L/T < 1500)

duplex mode to enhance performance. This is not an
IEEE standard.
