Data from wireless end devices should not go through more than three
wireless hops before it gets to an access point on the primary LAN.
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 the 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 in the
section “Using One Access Point in a Simple Wireless Network” on
page 22.
2. Configure the LAN ID. For help, see “Configuring the Spanning Tree
3. (802.11g and 802.11b) Configure the station radio in the point-to-point
bridge on the secondary LAN:
a. From the main menu, click the link corresponding to the station
radio. The radio screen appears.
b. In the Primary service set Node Type field, choose Station.
c. In the Primary service set SSID (Network Name) field, type the
SSID. In this example, the SSID is Manufacturing.
d. Click Submit Changes. The screen updates.
