No drop16,
A port will drop the transmitting packet after 16 consecutive
collisions if this function is turned on.
1: do not drop
0: drop
AGETIME, enable aging of address table
An address tag in hashing table will be dropped if this function
is turned on and its aging timer expires (300 seconds).
TWOPART, Turn on twopartD
IP175 examine the carrier for 64 bits only during its back off
period if this function is enabled. It makes IP175 have higher
priority in a collision event.
1: turn on
0: turn off
MODBCK, Turn on modified back off algorithm
IP175 uses modified (aggressive) back off algorithm if this
function is enabled. The maximum back off period is limited to
8-slot time. It makes IP175 have higher priority in a collision
event.
1: turn on
0: turn off
