LED[6][3]
Programs back-off aggressiveness for half-duplex mode.
D = Less aggressive back-off
F/U = More aggressive back-off (default
LED[6][2]
Programs retries for frames that encounter collisions.
LED[6][0]
Reserved – use float configuration
LED[7][3]
Programs flow control.
D = No flow control
F/U = Flow control enabled (default)
LED[7][2]
Programs broadcast storm protection.
D = 5% broadcast frames allowed
F/U = Unlimited broadcast frames (default)
LED[7][0]
Reserved – use float configuration
LED[8][3]
Programs address aging.
D = Aging disabled
F/U = Enable 5 minute aging (default)
LED[8][2]
Programs frame length enforcement.
D = Max length for VLAN is 1522 bytes and without VLAN is 1518 bytes
F/U = Max length is 1536 bytes (default)
LED[8][0]
Programs half-duplex back pressure.
D = No half-duplex back pressure
F/U = Half-suplex back pressure enabled (default)
EN1P
H
Enable 802.1p for all ports: this enables QoS based on the priority field in the
layer 2 header.
0 = 802.1p selected by port in EEPROM
1 = Use 802.1p priority field unless disabled in EEPROM
Note: This is also controlled by the EEPROM registers (registers 4-11 bit 4).
The values in the EEPROM supercede this pin. Also, if the priority selection is
unaltered in the EEPROM registers (register 3 bits 0-7) then values of ‘100’
and above are considered high priority and values of ‘011’ and below are low
priority.
X1
Clock
External crystal or clock input
X2
Clock
Used when other polarity of crystal is needed. This is unused for a normal
clock input.
SCL
Clock
Clock for EEPROM.
SDA
Serial data for EEPROM.
CTRL
RST#
L
System reset.
TEST
T[1], T[5]
Factory test inputs: leave open (float) for normal operation
RLPBK
H
Factory test input: tie low for normal operation
