UNH Mode
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.
R/W
0
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.

IEEE 802.3x Transmit
Flow Control Disable
0, will enable transmit flow control based on AN result.
1, will not enable transmit flow control regardless of AN result.
R/W
Pin PMRXD3
strap option.
Pull-down(0):
Enable Tx
flow control.
Pull-up(1):
Disable Tx/Rx
flow control.
Note:
PMRXD3 has
internal pull-
down.
4
IEEE 802.3x Receive
Flow Control Disable
0, will enable receive flow control based on AN result.
1, will not enable receive flow control regardless of AN result.
Note: Bit 5 and bit 4 default values are controlled by the same pin, but
they can be programmed independently.
R/W
Pin PMRXD3
strap option.
Pull-down (0):
Enable Rx
flow control.
Pull-up (1):
Disable Tx/Rx
flow control.
Note:
PMRXD3 has
internal pull-
down.
3
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) .
R/W
0
2
Aging Enable
1, Enable age function in the chip.
0, Disable aging function.
R/W
Pin LED[5][2]
strap option.
Pull-down (0):
Aging disable
Pull-up (1):
Aging enable.
Note:
LED[5][2] has
internal pull
up.
