The stations must be configured to operate in Peer-to-Peer mode.
An advanced Bridge Setup parameter for Access Point RLM that
enables you to influence which port should be included in the
Spanning Tree, when concurrent bridge ports of a single bridge unit
are connected in a loop.
A lower value makes a port more likely to become selected in the
Spanning Tree than the concurrent one that has a higher numerical
value. Valid values: 0-255. Initial value: '128'
A security option that enables you to create a network management
level by means of a password.
For example, the 'Read Password' in combination with the correct IP
address will authorize a local LAN administrator to display only the
RLM Manager Monitor function for a specific access point, but not to
view or modify the access point configuration.
You can set the 'Read Password' using the SNMP tab in the
RLM Manager program.
