3 - 18 Aironet PCMCIA Wireless LAN Adapter

Setting System Identifier

The SID is a 4-byte, hexadecimal digit value that is attached to each

packet sent out over the radio. Establishing a SID allows you to group

nodes into a microcellular network and exclude those nodes that are

within radio range on other networks.

The SID value must be an even number, cannot exceed 8 digits and must

start with 00 or 02. An example of valid SID values are: 00000102,

0200AA14, 00013A18, 007F6380. The default SID is 00000002.

Since nodes will only receive packets from other nodes with a matching

SID, you must make sure that the Aironet Client Card is set with the

same SID as other nodes on your Radio Network.

The System Identifier option also allows you to have the system auto-

matically set a SID value for you. To generate an automatic SID value,

click once on AUTO with the mouse, or press F10.

NOTE: All other units in the system must be manually set to this value.

Setting the Radio Node ID

The Radio Node ID represents the last 2-bytes of the 6-byte Network

Identifier, and is used to customize the radio address for the Aironet

Client Card.

If your LAN addresses are locally administered, you may want to set the

2-byte Radio Node ID to match those used on your LAN. If not, you

should ignore this parameter and use the Network Identifier outlined

below.
