MobileLAN access System Manual
You need to set the root priorities and secondary LAN bridge priorities for
the bridge on the primary LAN and for the bridge on the secondary LAN:
• On the primary LAN bridge, set the root priority to a number that is
greater than the root priority of the secondary LAN bridge. The access
points will not form a point-to-point bridge if the primary LAN bridge
has a lower root priority than the secondary LAN bridge.
• On the secondary LAN bridge, set root priority to 0 and the secondary
LAN bridge priority to a number other than 0.
You may also need to adjust the flooding parameters. Here are some
recommendations:
• If there are no end devices on the secondary LAN, the bridge on the
secondary LAN can use the default flooding settings. The Secondary
LAN Flooding parameter is disabled.
• If there are end devices on the secondary LAN, the bridge on the
secondary LAN should have Secondary LAN Flooding parameter set to
Multicast. If you also want unicast flooding, you can set this parameter
to Enabled.
• If there are end devices on the secondary LAN and the end devices
communicate with end devices on another secondary LAN, the root
access point should have its Multicast Flooding parameter set to
Universal. This setting ensures that all ARP requests and multicast
traffic is distributed through a second or third hop.
To install a point-to-point or a point-to-multipoint bridge
1 Follow the instructions for installing a simple wireless network on page
12.
2 Configure the LAN ID. For help, see "Configuring the Spanning Tree
Parameters" in Chapter 5.
3 (802.11b, OpenAir) Configure the station radio in the point-to-point
bridge on the secondary LAN.
From the main menu, click the link corresponding to the station
a
radio. The radio screen appears.
