In general, Proxim recommends that you leave this parameter set
to Yes unless Stations only need to communicate with the Master
and will never need to communicate with each other.
You need only set the Peer to Peer parameter on a Station or
Alternate Master. Masters will ignore this parameter if it is set.
Node Override
The Node Override field allows you to change the MAC address
that the RangeLAN2 card will broadcast during the current
network session. If this field is not filled out or an illegal address
is entered, the MAC address burned in at the factory will be used.
Illegal addresses include multicast addresses and non-hexadecimal
characters in the address. A multicast address contains an odd
number in the second digit. For example, the address
010000000000, is a multicast address and an illegal value for a
node override.
When displayed on a network analyzer or the RangeLAN2
Utilities, the address displayed will be that entered by the user but
with bit 2 of the most significant byte set. For example, if you
entered 000000000000 as the node override address,
020000000000 will be displayed as the node address. If you
entered 040000000000, 060000000000 will be displayed as the
node address. This is best understood when the digits are con-
verted into binary. Each hexadecimal digit of a MAC address is
represented by 4 binary characters. The digit 2 is represented as
0010, i.e., bit 2 of the most significant byte is set to 1. The digit 4
is represented as 0100 in binary, so this would be converted to
0110 (or 6 in decimal) so that bit 2 of the most significant byte
could be set. Note that this only affects the second digit of the
MAC address.
