Type Description
I
pu
Input upon reset = Disable Broadcast Storm Control.
1: Disable Broadcast Storm Control
0: Enable Broadcast Storm Control
Output after reset = used for LED.
I
pu
Input upon reset = Enable blinking of LEDs upon reset.
1: Enable power-on LED blinking for diagnosis
0: Disable power-on LED blinking
Output after reset = used for LED.
I
pu
Input upon reset = Enable Auto crossover detection.
1: Enable auto crossover detection
0: Disable auto crossover detection. MDI only
Output after reset = used for LED.
I
pu
Disable auto turn off of flow control ability.
1: Disable
0: Enable auto turn off flow control ability on the low priority queue
for 1~2 seconds whenever the port receives a high priority frame.
The flow control ability will be re-enabled if this port does not
receive another high priority frame during this 1~2 second duration
Output after reset = used for LED.
I
pu
Input upon reset = Enable forwarding of 802.1D specified reserved
group MAC address frames.
1: Forward reserved control packets with DID=01-80-C2-00-00-03
to 01-80-C2-00-00-0F
0: Filter reserved control packets with DID=01-80-C2-00-00-03 to
01-80-C2-00-00-0F
Output after reset = used for LED.
I
pu
Input upon reset = Enable carrier sense defering function.
1: Enable carrier sense deferring function for half duplex
backpressure
0: Disable carrier sense deferring function for half duplex
backpressure
Output after reset = used for LED.
I
pu
Enable 48 pass 1 mechanism.
1: 48 pass 1. Continuously collides 48 input packets then passes 1
packet to retain system resources and avoid repeater partition when
buffer is full
0: Continuously collides input packets to avoid packet loss when
buffer is full
Output after reset = used for LED.
I
pu
Input upon reset = Enable aggressive back-off mechanism.
1: Enable more aggressive back-off mechanism in half duplex mode
for performance enhancement. The back-off limitation will become 3
in this mode (default is 10)
0: Disable aggressive back-off mechanism in half duplex mode
Output after reset = used for LED.
