10 - 6 Aironet 340 Series Bridge Controlling Associations With Static Entries (Autoassoc/Add/Remove) Use the auto-association parameter and the static association table entries to control associations. In its default configuration, the bridge will allow any radio node in range to associate to it. For a more secure installation you must add static entries to the association table for these nodes. This allows control over which radio nodes are allowed to associate with which bridge. If auto-association is “On”, any radio node will be allowed to associate. If the parameter is “Off”, only nodes whose address matches a static table entry will be allowed to associate. Static table entries are association table entries added manually by the operator and saved in the configuration memory. To add an entry, use “Add” on the Association Menu. “Add” supplies the address of the node that is to be controlled.

Setting Up the Association Table 10 - 7 For example, suppose there is a bridge on your accounting LAN and three end nodes (A, B, and C) within radio range of the bridge. Only End Node A should be allowed access to the LAN. 1. Disable auto-association. 2. Add End Node A as a static entry. End Node A is allowed to associate to the root unit. 3. End Nodes B and C are not allowed to associate. Figure 10.1 - Example of Using Static Entry to Restrict Association Root Unit End Node A Wired LAN End Node B End Node C As another example, suppose you only wanted to block End Node C and did not care about any other nodes. In this case you would leave autoassociation “On” and add a static entry for End Node C to block it.

Controlling Associations With Static Entries (Autoassoc/Add/Remove)<br />

Use the auto-association parameter and the static association table<br />

entries to control associations.<br />

In its <strong>de</strong>fault configuration, the bridge will allow any radio no<strong>de</strong> in<br />

range to associate to it. For a more secure installation you must add<br />

static entries to the association table for these no<strong>de</strong>s. This allows control<br />

over which radio no<strong>de</strong>s are allowed to associate with which bridge.<br />

If auto-association is “On”, any radio no<strong>de</strong> will be allowed to associate.<br />

If the parameter is “Off”, only no<strong>de</strong>s whose address matches a static<br />

table entry will be allowed to associate.<br />

Static table entries are association table entries ad<strong>de</strong>d manually by the<br />

operator and saved in the configuration memory. To add an entry, use<br />

“Add” on the Association Menu. “Add” supplies the address of the no<strong>de</strong><br />

that is to be controlled.
