5 - Configuring the Spanning Tree

134

Example 1 The root (AP1), AP3, AP5, and AP6 service only wireless end devices.

These access points need to pass IP traffic, but not pass IPX traffic that

does not need to be forwarded to the primary or secondary LAN.

For this example, set these options on the Ethernet Frame Type Filters

screen. No subtype filters are needed.

Example 2 AP2 and AP4 (designated bridge) service end devices and the IP host

and IPX host on the secondary LAN. Also, these access points pass IPX

traffic.

The IPX router in this network periodically sends IPX RIP frames for

coordinating with other routers. These do not need to be forwarded to

the secondary LAN, because the secondary LAN does not contain a

router.

To filter the IPX RIP frames, you need to configure subtype filters. This

example sets filters for three different cases: DIX, 802.2, and 802.3 SNAP

frames. In many actual networks, only one type of filter is required,

because all stations are configured using one of the three options.
